Association between alopecia areata, anxiety, and depression: A systematic review and meta-analysis.

BACKGROUND: To date, there is no comprehensive meta-analysis analyzing the association between alopecia areata, anxiety, and depression. OBJECTIVE: We sought to analyze the existing literature to examine the association between alopecia areata, anxiety, and depression. METHODS: We extracted literature from 4 databases including MEDLINE, Embase, PsychINFO, and Web of Science. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (ie, PRISMA) reporting guidelines to finalize a list of relevant articles to be included in our systematic review and meta-analysis. There were no restrictions placed on publication year or age of participants. RESULTS: Eight studies that included 6010 patients with AA and 20 961 control individuals were included in the quantitative analysis. These included 4 cross-sectional studies and 4 case-control studies. Analysis of these studies showed a positive association with anxiety (pooled odds ratio, 2.50; 95% confidence interval, 1.54-4.06) and depression (pooled odds ratio, 2.71; 95% confidence interval, 1.52-4.82). LIMITATIONS: Publication bias may be a limitation of the study. CONCLUSION: This study suggests that patients with AA are at higher risk of both anxiety and depression. Health care professionals must be cognizant of this higher risk and consider routine assessment of these conditions and referral to appropriate providers when indicated.

Excess hair, hair removal methods, and barriers to care in gender minority patients: A survey study.

BACKGROUND: In gender minority patients, electrolysis and laser hair removal may be necessary to reduce facial and body hair in individuals seeking a more feminine appearance and/or modified gender expression. These procedures may also be required preoperatively for some gender-affirming surgeries. AIMS: To identify (a) the frequency of unwanted facial and body hair, (b) the use of various hair removal methods, and (c) associated barriers to care in gender minority patients. METHODS: An online-based patient survey was distributed via social media on Facebook® , YouTube® , and Instagram® in fall 2018. Respondents were at least 18 years old and self-identified as a gender minority. RESULTS: In total, 991 responses were recorded with a completion rate of 77%. Considering excess hair, 84% of transwomen on feminizing hormone therapy (FHT: estrogen and anti-androgen therapy), 100% of transwomen not on FHT, and 100% of nonbinary individuals on FHT reported excess facial/body hair. Laser hair removal (18%) and electrolysis (17%) had similar rates of use in this cohort and were more commonly reported for nonsurgical gender-affirming purposes than preoperative preparation. Cost was the most frequently cited barrier to care. CONCLUSION: As the majority of transwomen and nonbinary people on feminizing hormone therapy had persistent excess facial/body hair, routine use of gender-affirming hormones is not sufficient to fully eliminate unwanted hair. There remains a critical need to advocate for more comprehensive insurance coverage for laser hair removal and electrolysis in gender minority patients.

Development of Lichen Planopilaris-Like Alopecia following Occupational Exposure to Trichloroethylene and Tetrachloroethylene.

BACKGROUND: We report a case of acute and severe lichen planopilaris (LPP)-like alopecia in a 35-year-old male construction worker following occupational exposure to trichloroethylene (TCE) and tetrachloroethylene (PCE). CASE REPORT: Two weeks after initiating ground-intrusive construction at a previous dry-cleaning facility site, the patient developed sudden scalp pruritus and associated patchy hair loss. As subsequent scalp biopsies revealed LPP, he was started on hydroxychloroquine at 200 mg twice daily and clobetasol solution once daily. Despite treatment, the patient's hair loss rapidly progressed to involve >95% of his scalp within 3 years. An official "work clean" policy report revealed high-concentration exposure to TCE and PCE. CONCLUSION: Although causation cannot be proven, the close temporal relationship and rapid progression of LPP-like alopecia in an atypical patient demographic support a strong correlation between chemical exposure to TCE/PCE and scarring hair loss.

Gender-related cost discrepancies in a cohort of 110 facial moisturizers.

BACKGROUND: Gender-related price inequalities for over-the-counter dermatologic products such as shampoos and conditioners, razors, deodorants, and lotions remain prevalent in the marketplace. This trend has also been found to apply to topical minoxidil, a common treatment for male and female pattern hair loss. OBJECTIVE: We sought to identify the gender-related price discrepancies of facial moisturizers, which are routinely recommended by dermatologists. METHODS: Three online retailers (Amazon, Target, and Walmart) were surveyed for available facial moisturizers in October 2018. Facial moisturizers were classified as men's, women's, or gender-neutral based on three specific marketing variables: language, container color/graphics, and container curvature/shape. RESULTS: In total, 110 facial moisturizers were included in this analysis. Of the 54 facial moisturizers evaluated for men, 47 (87%) contained the word "men" within the marketing language, while only three of 56 (5.4%) facial moisturizers targeted at women were explicitly labeled "for women." No statistically significant difference was found between the number of facial moisturizers listed as fragrance-free, SPF-containing, anti-aging, or those labeled as sensitive, hypoallergenic, or dermatologist recommended between the two groups. However, facial moisturizers marketed to women were on average $3.09 more per ounce than those marketed to men. A two-tailed t test revealed a statistically significant difference between the price per ounce of facial moisturizers for men ($6.20) and those for women ($9.29) (P = 0.013). CONCLUSION: Facial moisturizers marketed to women were found to be significantly more expensive than comparable facial moisturizers marketed to men.

The effect of scalp cooling on CIA-related quality of life in breast cancer patients: a systematic review.

PURPOSE: Chemotherapy-induced alopecia (CIA) remains a distressing adverse event of cancer treatment but may be prevented by scalp cooling. The effectiveness of scalp cooling, however, is dependent on the chemotherapy regimen with successful hair preservation (i.e., < 50% hair loss) in 41-59% of women on taxane-based therapies in comparison to 16-36% on anthracycline-based therapies. Despite the potential utility, use of scalp cooling has shown a more equivocal impact on quality of life (QoL). In this review, we aim to evaluate the use of scalp cooling for CIA and quantitative QoL measures. METHODS: A systematic review of PubMed, Embase, Web of Science, and Cochrane databases for clinical studies on scalp cooling to prevent CIA published before October 29, 2018 was performed. Clinical studies with 5 or more patients that reported on a quantitative QoL measure were included and graded according to a modified five-point scale from the Oxford Centre for Evidence-Based Medicine. RESULTS: Studies meeting inclusion criteria included 4 randomized clinical trials (RCT), 8 cohort studies, and 1 cross-sectional study with 1282 unique patients. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (QLQ-C30: 46%) and Breast Cancer Module (QLQ-BR23: 46%) represented the most commonly used QoL assessments. Overall, 4 (31%) of the 13 studies concluded that scalp cooling was associated with significant improvements in QoL measures; 8 (62%) determined that there was either non-significant or no improvements; and 1 (7.7%) provided a mixed conclusion. Although 2 (50%) RCT demonstrated that scalp cooling can effectively prevent CIA depending on the chemotherapy regimen, these studies did not show that successful hair preservation was associated with improved QoL measures. CONCLUSIONS: This review demonstrates that scalp cooling is not consistently associated with significant QoL improvements as assessed by EORTC QLQ-C30 and -BR23. Representing a critical limitation, more than one-third of the studies did not subcategorize QoL outcomes for successfully or unsuccessfully scalp-cooled patients but rather reported on QoL measures for all scalp-cooled patients in general. Failure to prevent hair loss in patients undergoing an expensive and potentially uncomfortable treatment likely contributes to decreased well-being, impacting the overall distribution of QoL measures in scalp cooling patients compared to controls. Future studies should incorporate validated QoL instruments specific to hair disease and classify QoL outcomes for scalp-cooled patients based on the degree of hair preservation.

The Medical and Psychosocial Associations of Alopecia: Recognizing Hair Loss as More Than a Cosmetic Concern.

Alopecia encompasses a broad range of hair loss disorders, generally categorized into scarring and non-scarring forms. Depending on the specific pathogenesis of hair loss and geographic location, a number of psychiatric and medical comorbidities, including but not limited to thyroid disease, lupus erythematosus, diabetes mellitus, atopic dermatitis, sinusitis, coronary artery disease, anxiety, depression, and suicidality, have been identified in association with alopecia. In addition to the numerous associated comorbid conditions, patients with alopecia report decreased quality-of-life measures across symptomatic, functional, and global domains. While alopecia can affect patients of all ages, genders, and ethnicities, hair loss may more significantly impact women as hair represents an essential element of femininity, fertility, and female attractiveness in society. Individuals of lower socioeconomic status may also face health disparities in the context of alopecia as a majority of hair loss treatments are considered cosmetic in nature and accordingly are not covered by third-party insurance providers. Although traditionally thought of as a merely aesthetic concern, alopecia encompasses a significant burden of disease with well-defined comorbid associations and genuine psychosocial implications, and thus should be assessed and managed within a proper medical paradigm.
