Laser sources have established their potential effect in inducing hair regrowth. No large cohort study has evaluated the effect of ablative fractional 2940-nm erbium yttrium aluminum garnet (Er: YAG) laser in the treatment of androgenetic alopecia (AGA). To investigate the efficacy and safety of the ablative fractional 2940-nm Er: YAG laser in combination with medication therapy for the treatment of AGA. We performed a retrospective study between first July 2021 to 30th December 2021. All included patients received oral finasteride and topical minoxidil, or combined with six sessions of Er: YAG laser at 2-week intervals. Patients were divided into medication or combined therapy groups. The efficacy of the two therapies was evaluated by the investigator's Global Assessment (IGA) scores and the patient's Likert satisfaction scale at week 12 and week 24. Changes in total, terminal and villous hair count, total and terminal hair diameter, and AGA grade were also recorded. Adverse events were evaluated at each follow-up. A total of 192 male patients with AGA were included, including 67 receiving combination treatment, and 125 receiving medication treatment. At week 24, the combination treatment afforded superior outcomes in the IGA score, patient's global assessment, total and terminal hair counts, and diameters (all P<0.05). No severe adverse events were reported in both groups. The combined therapy of ablative fractional Er: YAG laser and medication was superior in treating male AGA than single medication therapy without serious adverse effects.

Although finasteride (FNS) tablets are considered the most effective drug for the treatment of androgenetic alopecia (AGA), their clinical applications are limited due to the associated side effects including decreased libido, breast enlargement, and liver dysfunction. In this study, we have developed a personalized microneedle (PMN) with a double-layer structure that incorporates FNS-loaded microspheres (MPs) to accommodate irregular skin surfaces. This design enables the sustained release of FNS, thereby reducing potential side effects. The needle body was synthesized with high-strength hyaluronic acid (HA) as the base material substrate. The backing layer utilized methacrylate gelatin (GelMA) with specific toughness, enabling PMN to penetrate the skin while adapting to various skin environments. The length of PMN needles (10 × 10) was approximately 600 µm, with the bottom of the needles measuring about 330 µm × 330 µm. The distance between adjacent tips was around 600 µm, allowing the drug to penetrate the stratum corneum of the skin. The results of the drug release investigation indicated the sustained and regulated release of FNS from PMN, as compared to that of pure FNS and FNS-MPs. Further, the cytotoxicity assay demonstrates that PMS displays good cytocompatibility. Altogether, this mode of administration has immense potential for the development of delivery of other drugs, as well as in the medical field.

Finasteride, a 5α-Reductase inhibitor, is used to treat male pattern baldness and benign prostatic hyperplasia. Several clinical studies show that chronic finasteride treatment induces persistent depression, suicidal thoughts and cognitive impairment and these symptoms are persistent even after its withdrawal. Previous results from our lab showed that repeated administration of finasteride for six days induces depression-like behavior. However, whether short-term finasteride administration induces anxiety-like behavior and memory impairment and alters synaptic plasticity are not known, which formed the basis of this study. Finasteride was administered to 2-2.5 months old male Wistar rats for six days and subjected to behavioral evaluation, biochemical estimation and synaptic plasticity assessment. Anxiety-like behavior was evaluated in the elevated plus maze (EPM), open field test (OFT), light/dark test (LDT), and novelty suppressed feeding test (NSFT), and learning and memory using novel object recognition test (NORT) and novel object location test (NOLT) and depression-like behavior in the sucrose preference test (SPT). Synaptic plasticity in the hippocampal Schaffer collateral-CA1 was evaluated using slice field potential recordings. Plasma corticosterone levels were estimated using ELISA. Finasteride administration induced anxiety-like behavior in the EPM, OFT, LDT and NSFT, and depression-like behavior in the SPT. Further, finasteride induced hippocampal dependent spatial learning and memory impairment in the NOLT. In addition, finasteride decreased basal synaptic plasticity and long-term potentiation (LTP) in the hippocampus. A trend of increased plasma corticosterone levels was observed following repeated finasteride administration. These results indicate the potential role of corticosterone and synaptic plasticity in finasteride-induced effects and further studies will pave way for the development of novel neurosteroid-based therapeutics in neuropsychiatric diseases.

BACKGROUND: Currently, there is only one topical medication approved by the U.S. Food and Drug Administration for alopecia, minoxidil 2.5% and 5%. With limited options, dermatologists often turn to compounding pharmacies for customized topical alopecia medications. OBJECTIVES: (1) to investigate the pricing and availabilities of compounded topical alopecia medications and (2) to investigate the delivery/mail options available. METHODS: 103 dermatological compounding pharmacies in the tri-state area were contacted. Data were collected on the prices of 11 different compounded formulations for alopecia, the highest concentration of minoxidil available, compounding accreditation status, and delivery. RESULTS: The majority (76.7% [79/103]) of pharmacies surveyed were responsive. Mean prices for 60 g or mL of medication were $70.44 for minoxidil 5%, $86.95 for minoxidil 5%/finasteride 0.5%, $159.13 for minoxidil 5%/bimatoprost 0.03%, $141.91 for minoxidil 5%/latanoprost 0.02%, $75.31 for finasteride 0.5%, $204.41 for tacrolimus 0.3%, $220.11 for tacrolimus 0.3%/minoxidil 5%/clobetasol 0.05%, $71.44 for cetirizine 1%, $74.93 for metformin 10%, $4,273.20 for tofacitinib 2%, and $1,840.42 for ruxolitinib 2%. Nearly all (93.5% [72/77]) of the pharmacies reported being able to compound minoxidil higher than the commercially available 5%, while 67.6% (50/74) were able to customize minoxidil to be made with <10% alcohol. Just over half (56.4% [44/78]) of the pharmacies were able to deliver to all tri-state areas. The mean delivery fee of pharmacies was $5.93 (n=77). Almost all of the pharmacies (98.7% [76/77]) claimed to be able to process and deliver medications within a week. If pharmacies were not located in the local vicinity, 44.6% (29/65) used a mailing service. CONCLUSION: This survey serves to expand clinicians' and patients' knowledge of the options and prices of topical compounded medications for alopecia.

Finasteride is used in female-pattern hair loss, hirsutism, and polycystic ovarian syndrome. It inhibits 5α-reductase, which is an important enzyme in the biosynthesis of neurosteroids. The effects of finasteride treatment on mental health in female patients as well as the effects of repeated/chronic finasteride administration in female rodents are still unknown. Accordingly, in our study, we administered finasteride (10, 30, or 100 mg/Kg, s.c.) for 6 days in female rats and evaluated behavior, plasma steroid levels, and synaptic plasticity. Depression-like behavior was evaluated using forced swim test (FST) and splash test. Anxiety-like behavior was evaluated using novelty-suppressed feeding task (NSFT), elevated plus maze (EPM), open field test (OFT), and light-dark test (LDT). Plasma steroid levels were assessed using ELISA and synaptic plasticity by field potential recordings. We observed that finasteride decreased total immobility duration in FST, indicating antidepressant-like effect and decreased the latency to first bite in NSFT, showing anxiolytic-like effect. We also found a significant increase in plasma estradiol and a significant decrease in plasma corticosterone level. Furthermore, field potential recordings showed that finasteride increased hippocampal long-term potentiation. These results indicate that repeated finasteride administration in female rats may have antidepressant- and anxiolytic-like effect, which might be mediated by enhanced estradiol levels or decreased corticosterone levels. Further studies are required to validate the molecular mechanisms underlying the effects of finasteride in female rats. Understanding the mechanisms will help us in developing novel neurosteroid-based therapeutics in the treatment of neuropsychiatric disorders in women.

PURPOSE: To compare the urological and sexual outcomes of using either tamsulosin/finateride or tadalafil/finasteride as combination therapies in patients with large prostate. PATIENTS AND METHODS: Selection criteria included prostate volume > 40 ml and IPSS > 7. Patients with severe erectile dysfunction (IIEF-erectile functions ≤ 10) were excluded. Patients were randomized into group I (tamsulosin/finasteride) and group II (tadalafil/finasteride). The primary endpoint was to define urinary and sexual function changes (IPSS, IPSS-quality of life, urinary flow rates and IIEF domains) within each group. The secondary endpoint was to compare the treatment induced changes between both groups. RESULTS: At 4th and 12th weeks, 131 and 127 patients were available in both groups, respectively. Both groups showed significant LUTS improvement (IPSS changes: - 4.9 ± 2.7 and - 4.3 ± 2.9 at 4th week and - 6.1 ± 3 and - 5.4 ± 2.8 points by the 12th week in both groups, respectively). Group I had better average flow rates at both follow-up visits. Meanwhile, maximum flow rates were comparable in both groups at 12th week (13.5 ± 3.9vs. 12.6 ± 3.7, p > 0.05). In group I, all IIEF domains were significantly lowered at both visits (p < 0.05). Group II showed significant increase in IIEF-erectile function scores (1.3 ± 1.1 and 1.8 ± 1.2 at the 4th and 12th weeks) with a transient significant reduction of IIEF-orgasm and sexual desire noted only by the 4th week (- 0.8 ± 0.4 and - 0.6 ± 0.4, respectively). CONCLUSION: Within three months, both combinations are comparably effective in improving BPH related LUTS. Tamsulosin/finasteride provided significantly better Qmax only at 4th week. Tadalafil/finasteride had the advantage of improving sexual performance over the other combination.

The objective of this study was to evaluate the impact of finasteride on the progression of prostate intraepithelial neoplasia and levels of prostate-specific antigen (PSA) in patients. A total of 120 patients with high-grade prostatic intraepithelial neoplasia were included in this study from January 2013 to January 2018. All patients underwent prostate biopsies. Among them, 60 patients were assigned to the observation group and received a daily dosage of 5 mg finasteride for 60 months, while the remaining 60 patients were assigned to the control group and did not receive finasteride. PSA levels were measured every six months, and imaging scans were conducted throughout the five-year study period. Additional biopsies were performed if PSA levels exceeded 10 ng/mL or imaging suggested the presence of prostate cancer. Statistical analysis was applied to the collected data. In total, 25 cases of prostate cancer were identified in this study. Of these cases, 7 patients belonged to the observation group, whereas the remaining 18 patients were from the control group. The observation group exhibited significantly lower levels of total serum PSA (p < 0.001) and Gleason scores (p < 0.001) compared to the control group. Our study, which involved 120 participants, demonstrated that finasteride effectively reduces serum PSA levels and mitigates the severity of prostate cancer. These findings suggest that finasteride holds potential as a treatment option for patients with -high-grade prostatic intraepithelial neoplasia.

INTRODUCTION: Treating alopecia can be challenging. The available treatments are topical minoxidil, low-dose oral minoxidil (LDOM), and 5-α reductase inhibitors like finasteride and dutasteride. Only topical minoxidil and finasteride 1 mg daily are FDA-approved, while the rest are used off-label. Recent research has suggested that oral minoxidil may be a safe and effective treatment for both female androgenetic alopecia (female AGA) and male androgenetic alopecia (male AGA). AREAS COVERED: In this review, we explore the pharmacokinetics, mechanism of action, safety, and efficacy of oral minoxidil. Additionally, we discuss its effectiveness compared to other treatments available for female AGA and male AGA. EXPERT OPINION: LDOM has demonstrated a favorable efficacy and safety profile in several trials. Subsequently, its use for the treatment of male AGA and female AGA is increasing. However, its use remains off-label, and through increased usage, we will get a better idea of the best dosage and monitoring guidelines. LDOM has also been used with some effectiveness in other forms of hair loss.

OBJECTIVE: To identify which medications are mostly associated with ejaculatory disorders through a disproportionality analysis. METHODS: The Food and Drug Administration Adverse Event Reporting System (FDA-FAERS) and the Eudra-Vigilance (EV) database were queried to identify medications more commonly associated to ejaculatory disorders from September 10, 2012 to June 1, 2023. Proportional Reported Ratios (PRRs) were computed for all the selected drugs. RESULTS: Overall, 7404 reports of ejaculatory disorders reports were identified, and of these, 6854 cases (92.6%) were attributed to ten specific medications. On FDA-FAERS and EV databases, Paroxetine and Tamsulosin were the main responsible of delayed ejaculation (103/448 events, 23.0%) and retrograde ejaculation (366/1033 events, 35.4%), respectively. Finasteride was mostly related to painful ejaculation and ejaculation failure, with 150 events (7.8%) and 735 events (38.4%) respectively. Within the group of high-risk medications, Sildenafil presented higher risk of ejaculatory disorders than Tadalafil (PRR=5.85 (95%CI 5.09-6.78), P < .01). CONCLUSION: Ten drugs were recognized to display significant reporting levels of ejaculatory disorders. Among them, Finasteride and Sildenafil were responsible for the most reports in FDA-FAERS and in EV databases, respectively. Physicians should thoroughly counsel patients treated with these drugs about the risk of ejaculatory disorders. Further integration into clinical trials is needed to enhance the applicability and significance of these results.

Hair loss, or alopecia, is a prevalent condition in modern society that imposes substantial mental and psychological burden on individuals. The types of hair loss, include androgenetic alopecia, alopecia areata, and telogen effluvium; of them, androgenetic alopecia is the most common condition. Traditional treatment modalities mainly involve medical options, such as minoxidil, finasteride and surgical interventions, such as hair transplantation. However, these treatments still have many limitations. Therefore, exploring the pathogenesis of hair loss, specifically focusing on the development and regeneration of hair follicles (HFs), and developing new strategies for promoting hair regrowth are essential. Some emerging therapies for hair loss have gained prominence; these therapies include low-level laser therapy, micro needling, fractional radio frequency, platelet-rich plasma, and stem cell therapy. The aforementioned therapeutic strategies appear promising for hair loss management. In this review, we investigated the mechanisms underlying HF development and regeneration. For this, we studied the structure, development, cycle, and cellular function of HFs. In addition, we analyzed the symptoms, types, and causes of hair loss as well as its current conventional treatments. Our study provides an overview of the most effective regenerative medicine-based therapies for hair loss.

A negative impact of finasteride on fertility has been reported, in which over production of reactive oxygen species and apoptosis were implicated. Hesperidin, a plant-derived bioflavonoid with antioxidant and anti-apoptotic effects, may mitigate these adverse effects. In order to investigate the possible protective role of hesperidin against finasteride-induced seminiferous tubules toxicity in adult male Wistar rats, 60 rats were randomized into five groups (I-V) receiving distilled water, 0.5% sodium carboxymethylcellulose solution, hesperidin, finasteride, and combined hesperidin and finasteride respectively. Testicular weight, sperm count and motility were determined. Testicular tissue homogenates were prepared to measure the level of malondialdehyde (MDA), total antioxidant capacity (TAC), reduced glutathione (GSH) and the gene expression of caspase-3 and B-cell lymphoma 2 (Bcl2). Testes were processed for light and electron microscopic evaluation. Johnsen score was calculated. Administration of finasteride resulted in significantly decreased testicular weights, sperm count and motility, Johnsen score, tissue levels of TAC and GSH together with significant increase in tissue MDA. Gene expression revealed significantly increased caspase-3 and decreased Bcl2. Furthermore, finasteride disrupted the seminiferous tubules, causing degenerative changes affecting Sertoli cells and spermatogenic cells. Co-administration of hesperidin with finasteride resulted in improvement in testicular weights, TAC, GSH, Bcl2, Johnsen score, sperm count and motility as well as preservation of the structure of the seminiferous tubules. To conclude, hesperidin was found to have a protective potential on finasteride-induced oxidative stress, apoptosis and testicular structural damage.

Finasteride is commonly used for androgenetic alopecia (AGA) treatment. The aim of this study was to assess the therapeutic maintenance effect of a finasteride every other month (EOM) regimen and analyze clinical and laboratory differences in patients with AGA according to their treatment response. One hundred males with AGA who received finasteride 1 mg daily treatment for a year were enrolled in the study. At 1 year follow-up, treatment responses of patients who completed the visit schedule were assessed using five scales. The patients were assigned to good or bad response groups according to their assessment. Further, they were randomly divided into two groups (daily vs. EOM) and treated with finasteride (1 mg) for 1 more year. At 2 years follow-up, treatment efficacy was assessed. At 1-year follow-up, 36 patients completed the schedule, including eight and three patients in the good and bad response groups, respectively. At the 2-year follow-up, 23 patients completed the schedule, with nine in the daily group and 14 in the EOM group. Changes in global photographic assessment in the second year were 1.33 and 1.29 for the daily and EOM groups, respectively. The daily group showed an elevated hair density and lower concentration of dihydrotestosterone (DHT) and the DHT to testosterone ratio (DHT/T). However, the EOM group showed decreased hair density and elevated DHT and DHT/T. Following treatment response assessment after 1 year of treatment, the good response group showed early onset which was associated with maternal AGA. Analysis of serum androgen hormone magnitude of DHT reduction was much greater (54.4% vs. 44.4%). DHT/T was higher in the bad response group (1.98 vs. 2.33). We concluded that the finasteride EOM regimen showed similar maintenance effects to the daily regimen.

Finasteride is commonly prescribed to treat benign prostate hyperplasia and male-pattern baldness in cis men and, more recently, trans individuals. However, the effect of finasteride on cardiovascular disease remains elusive. We evaluated the role of finasteride on atherosclerosis using low-density lipoprotein (LDL) receptor-deficient (Ldlr-/-) mice. Next, we examined the relevance to humans by analyzing the data deposited between 2009 and 2016 in the National Health and Nutrition Examination Survey. We show that finasteride reduces total plasma cholesterol and delays the development of atherosclerosis in Ldlr-/- mice. Finasteride reduced monocytosis, monocyte recruitment to the lesion, macrophage lesion content, and necrotic core area, the latter of which is an indicator of plaque vulnerability in humans. RNA sequencing analysis revealed a downregulation of inflammatory pathways and an upregulation of bile acid metabolism, oxidative phosphorylation, and cholesterol pathways in the liver of mice taking finasteride. Men reporting the use of finasteride showed lower plasma levels of cholesterol and LDL-cholesterol than those not taking the drug. Our data unveil finasteride as a potential treatment to delay cardiovascular disease in people by improving the plasma lipid profile.

Post-finasteride syndrome and post-SSRI sexual dysfunction, are two poorly explored clinical conditions in which men treated for androgenetic alopecia with finasteride or for depression with SSRI antidepressants show persistent side effects despite drug suspension (e.g., sexual dysfunction, psychological complaints, sleep disorders). Because of some similarities in the symptoms, common pathological mechanisms are proposed here. Indeed, as discussed, clinical studies and preclinical data obtained so far suggest an important role for brain modulators (i.e., neuroactive steroids), neurotransmitters (i.e., serotonin, and cathecolamines), and gut microbiota in the context of the gut-brain axis. In particular, the observed interconnections of these signals in these two clinical conditions may suggest similar etiopathogenetic mechanisms, such as the involvement of the enzyme converting norepinephrine into epinephrine (i.e., phenylethanolamine N-methyltransferase). However, despite the current efforts, more work is still needed to advance the understanding of these clinical conditions in terms of diagnostic markers and therapeutic strategies.

Despite its efficacy for treating androgenetic alopecia, finasteride, an inhibitor of 5α-reductase (i.e., the enzyme converting testosterone, T, into dihydrotestosterone, DHT), is associated with several side effects including sexual dysfunction (e.g., erectile dysfunction). These side effects may persist after drug suspension, inducing the so-called post-finasteride syndrome (PFS). The effects of subchronic treatment with finasteride (i.e., 20 days) and its withdrawal (i.e., 1 month) in rat corpus cavernosum have been explored here. Data obtained show that the treatment was able to decrease the levels of the enzyme 5α-reductase type II in the rat corpus cavernosum with increased T and decreased DHT levels. This local change in T metabolism was linked to mechanisms associated with erectile dysfunction. Indeed, by targeted metabolomics, we reported a decrease in the nitric oxide synthase (NOS) activity, measured by the citrulline/arginine ratio and confirmed by the decrease in NO2 levels, and a decrease in ornithine transcarbamylase (OTC) activity, measured by citrulline/ornithine ratio. Interestingly, the T levels are negatively correlated with NOS activity, while those of DHT are positively correlated with OTC activity. Finasteride treatment also induced alterations in the levels of other molecules involved in the control of penile erection, such as norepinephrine and its metabolite, epinephrine. Indeed, plasma levels of norepinephrine and epinephrine were significantly increased and decreased, respectively, suggesting an impairment of these mediators. Interestingly, these modifications were restored by suspension of the drug. Altogether, the results reported here indicate that finasteride treatment, but not its withdrawal, affects T metabolism in the rat corpus cavernosum, and this alteration was linked to mechanisms associated with erectile dysfunction. Data here reported could also suggest that the PFS sexual side effects are more related to dysfunction in a sexual central control rather than peripheral compromised condition.

BACKGROUND: Minoxidil and the 5-alpha reductase inhibitors (5-ARIs), specifically, dutasteride and finasteride, are usually used to treat pattern hair loss (PHL), but evidence on the relative effectiveness of these drugs is far less for women than men. AIMS: We performed an age-adjusted network meta-analysis (NMA) to determine the comparative efficacy of monotherapy with the three agents-in any dosage and administrative route-on PHL in adult women. METHODS: The peer-reviewed literature was systematically reviewed to obtain data for our NMA. The outcome measure for our NMA was "change in total hair density." We referred to "regimen" as an "agent and its dosage;" our Bayesian NMA estimated regimens' surface under the cumulative ranking curve (SUCRA) values and pairwise relative effects. RESULTS: Our NMA used data from 13 trials-across which the following 10 regimens were identified (in decreasing order of SUCRA): 5 mg/day finasteride for 24 weeks (SUCRA = 95.7%), 5% topical minoxidil solution twice daily for 24 weeks (SUCRA = 89.5%), 1 mg/day minoxidil for 24 weeks (SUCRA = 78.1%), 5% topical minoxidil foam 1 half capful/day for 24 weeks (SUCRA = 66.5%), 3% topical minoxidil solution 1 mL twice daily for 24 weeks (SUCRA = 45.1%), 2% topical minoxidil solution 1 mL twice daily for 24 weeks (SUCRA = 44.6%), 5% topical minoxidil solution 1 mL/day for 24 weeks (SUCRA = 41.7%), 0.25 mg/day minoxidil for 24 weeks (SUCRA = 35.5%), 1.25 mg/day finasteride for 24 weeks (SUCRA = 24.8%) and 1 mg/day finasteride for 24 weeks (SUCRA = 4.3%). CONCLUSION: Our findings can improve clinical guidelines and help dermatologists manage female PHL more optimally with the available options.

INTRODUCTION: Androgenic alopecia (AGA) is the most common cause of hair loss in women, affecting their quality of life. The present study was conducted with the aim of comparing the combined effect of topical minoxidil and oral spironolactone with the combined effect of topical minoxidil and oral finasteride in women with AGA, female and male hair loss patterns. METHOD: This clinical study was performed on 60 women suffering from AGA. The patients were divided into two groups receiving spironolactone 100 mg/day and finasteride 5 mg/day. In addition, a 2% minoxidil solution was used in all patients in addition to treatment with finasteride or spironolactone. At 2 months after initiation and at the end of treatment, patients were evaluated using the Ludwig/Norwood-Hamilton scale and the degree of physician and patient satisfaction. RESULTS: After 2 months, hair density, hair thickness, and hair loss had improved in both groups; however, statistically, there was no significant difference between the two groups with respect to these parameters (p > 0.05). After 4 months, a significant difference was found between the two groups in terms of treatment response (physician satisfaction), hair density, and hair loss severity. So that, the drugs used were ineffective in 6.7% of cases in the minoxidil-spironolactone group and in 16.7% of cases in the minoxidil-finasteride group. In addition, 43.3% of cases in the minoxidil-spironolactone group and 53% in the minoxidil-finasteride group responded well to treatment. The treatment effect was excellent in 56.7% and 0% of the mentioned groups, respectively, and the mentioned difference was statistically significant (p: 0.01). The response to treatment in female pattern hair loss (FPHL) was not statistically significant (p: 0.52), but there was a significant difference in the response to both treatments in male pattern hair loss (MPHL; p: 0.007). In terms of patient satisfaction, minoxidil-spironolactone treatment was significantly better than minoxidil-finasteride regarding hair density and severity of hair loss (p: 0.01). Finally, in terms of treatment complications, the patients in two groups did not have any serious adverse effects. CONCLUSION: The combination of minoxidil and spironolactone could be considered a more effective treatment than the combination of minoxidil and finasteride in women with AGA, FPHL, and MPHL.

BACKGROUND: Frontal fibrosing alopecia (FFA) is a cicatricial alopecia with rapid epidemic growth. However, there is no agreement on the best therapeutic approach. AIMS: To compare the therapeutic effects of finasteride as a first-line systemic treatment of FFA versus hydroxychloroquine as a relatively safe and effective immunosuppressive drug. METHODS: Thirty-four female FFA patients were randomly assigned to receive either 400 mg/day of hydroxychloroquine or 2.5 mg/day of finasteride for 6 months. Topical treatments in both groups include pimecrolimus, mometasone, and minoxidil. Treatment efficacy was evaluated using the Frontal Fibrosing Alopecia Severity Score (FFASS), photography, and trichoscopy after 3 and 6 months. RESULTS: Both the finasteride and hydroxychloroquine groups showed significant improvements in FFASS and trichoscopic scores (p < 0.01). However, there was no significant difference between the two groups during the study. Photographic assessment showed that more than 60% of patients in both groups had improved without statistically significant differences between the two groups. CONCLUSIONS: Both finasteride and hydroxychloroquine are equally effective, safe, and well-tolerable for treating FFA patients.

Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization.1 It can cause cosmetic problems leading to psychological distress among affected men and women. Effective standard medical treatments available are topical minoxidil 2 to 5%, oral finasteride, oral dutasteride, and hair transplantation.1 However, some patients do not achieve favorable results with standard treatments. For these reasons, other novel treatments have been developed, including new medications, regenerative medicines (autologous platelet-rich plasma, adipose-derived stem cells, micrograft generation, and exosome), and low-level laser therapy.

PURPOSE: Topical minoxidil (MNX) 2%-5% and oral finasteride (F) 1 mg/day are the only two pharmacological treatments authorized for androgenetic alopecia (AGA). Recently, a 2.2 mg/mL topical formulation of F was developed to minimize the systemic adverse effects associated with the oral formula. MNX and F act through different mechanisms; therefore, their association could improve clinical efficacy. To evaluate the efficacy of the association of 5% MNX and 0.25% topical F compared to their use in monotherapy, a 6-month, prospective, randomized, assessor-blinded trial was conducted. PATIENTS AND METHODS: Forty-two males, mean age 24 ± 3 years, with AGA (I-VII of Norwood-Hamilton Grading Scale), treatment naive or free from any therapy for at least 6 months, were enrolled and randomly assigned to three arm treatment groups (2:1:1): group A (n = 19, the subjects applied 5% MNX in the morning and F spray in the evening), group B (n = 12, the subjects applied F spray in the evening), and group C (n = 11, the subjects applied 5% MNX twice daily). The efficacy of treatments was evaluated at baseline and after 3 and 6 months using a global photography score (GPAS; from -3 to +3) and trichoscopy evaluation and assessed by an investigator unaware of treatment allocation. At baseline and after treatments, the serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEA-S), and testosterone were also evaluated. RESULTS: All treatments resulted in an increase in hair density compared to baseline. However, this improvement was significant only for group A (MNX + F), both at three (+56 density/cm2 , p < 0.05) and six (+81 density/cm2 , p < 0.001) months. The mean change from baseline in hair density was higher for group A compared to other groups and statistically different compared to group B (F) (p < 0.01), both after 3 and 6 months. Group A showed a global photographic assessment score (GPAS) significantly higher compared to group B (p < 0.001) and group C (p < 0.05) both at 3 and 6 months (2.0 ± 0.7 vs. 0.6 ± 0.8 and 1.3 ± 0.6; respectively). A significantly greater percentage of subjects in Group A achieved a GPAS score of ≥2 in comparison with Groups B and C both after 3 and 6 months (79% vs. 8% and 41%, respectively). No significant differences were observed in mean hair diameter and hormonal levels between the three groups. Good tolerability was observed in all treated groups. CONCLUSION: The association of 5% MNX lotion and 0.25% F in spray formulation in patients with AGA showed a significantly higher clinical and instrumental efficacy compared to the monotherapies, with comparable tolerability and safety profile.
