Platelet-Rich Plasma as a Treatment for Androgenetic Alopecia.

BACKGROUND: Platelet-rich plasma (PRP) treatment may encourage hair growth by promoting cellular maturation, differentiation, and proliferation. OBJECTIVE: The objective of this study was to evaluate the effectiveness of PRP as a treatment for androgenetic alopecia (AGA). MATERIALS AND METHODS: A literature search combined with meta-analysis was used to calculate the overall standardized mean difference (SMD) in hair density in patients treated with PRP injections in comparison with baseline and placebo treatment. Chi squared analysis and Fisher exact test were used to investigate variation in protocols. RESULTS: The overall SMD in hair density was 0.58 (95% confidence interval [CI]: 0.35-0.80) and 0.51 (95% CI: 0.23-0.80, p < .0004) in favor of PRP treatment when compared with baseline and placebo treatment, respectively. CONCLUSION: Platelet-rich plasma is beneficial in the treatment of AGA. It is recommended that 3 monthly sessions of PRP (once monthly ×3 treatments) be used followed by a 3- to 6-month maintenance period.

Double-Blind, Placebo-Controlled Pilot Study on the Use of Platelet-Rich Plasma in Women With Female Androgenetic Alopecia.

BACKGROUND: Platelet-rich plasma (PRP) has been suggested as a therapeutic intervention for female androgenetic alopecia. OBJECTIVE: To perform a pilot study on the effect of PRP scalp injections in women with female androgenetic alopecia. MATERIALS AND METHODS: This double-blind, multicenter, placebo-controlled study compared the effect of PRP with that of saline placebo as scalp injection. The endpoints were hair count and hair mass index (HMI), along with patient-opinion survey responses. Platelet-rich plasma was manufactured from patients' blood using the Angel PRP system. RESULTS: Hair mass index or hair count did not statistically significantly differ between the study and placebo groups. However, 13.3% of the treatment subjects (vs 0% of the placebo subjects) experienced substantial improvement in hair loss, rate of hair loss, hair thickness, and ease of managing/styling hair, and 26.7% (vs 18.2% of the placebo group) reported that their hair felt coarser or heavier after the treatment. CONCLUSION: Platelet-rich plasma failed to demonstrate any statistically significant improvement in HMI or hair count in women with congenital female pattern hair loss. The patient survey results suggest a therapeutic advantage of PRP as perceived by patients but not according to hair count or HMI.

Core competencies for hair restoration surgeons recommended by the International Society of Hair Restoration Surgery.

BACKGROUND: Because hair restoration surgery has changed so significantly, the International Society of Hair Restoration Surgery (ISHRS) recently developed and published a Core Curriculum for Hair Restoration Surgery (CCHRS). The ISHRS organized a task force to develop training programs that would not only present the CCHRS but also provide the practical experience necessary to allow a physician to practice safe, aesthetically sound hair restoration surgery. The task force recognized early on that identification of core competencies for hair restoration surgeons was essential to guiding the development of these training experiences. This article presents the competencies that have been identified. OBJECTIVE: The intent of the Core Competencies for Hair Restoration Surgery is to outline the knowledge and skills that are essential to accurately diagnose and treat hair loss, to ensure patient safety, and to optimize aesthetic results. The ISHRS hopes that all existing surgery and dermatology training programs teaching hair restoration surgery procedures will find the Core Competencies useful in developing their curriculums. METHODS: The Core Competencies were developed through an organized review of the CCHRS by a team of experienced hair restoration surgeons and educators and reviewed and approved by the ISHRS Board of Governors. RESULTS: The diversity of these competencies demonstrate that contemporary hair restoration surgery is a specialty requiring knowledge of several medical disciplines, including genetics, endocrinology, dermatology, tissue preservation, and surgery. CONCLUSION: The International Society of Hair Restoration Surgery believes identification of these Core Competencies is an important contribution to physician education in hair restoration surgery, and physicians who demonstrate competency in these skills will satisfy patients with contemporary results in a safe environment.

Incorporating hair replacement into your practice.

The author defines the essential management skills that are unique to building a successful hair restoration surgery team and contrasts these skills with those needed to manage a general cosmetic surgery practice. Strategies for hair technician selection, training, supervision, and management are discussed, emphasizing the management skill areas that are different from those of general medical office or cosmetic surgery practices. Attention is given to the components of a contemporary hair restoration surgery operating suite: size, specialized equipment and tools, and essential support systems.

Core curriculum for hair restoration surgery, recommended by the International Society of Hair Restoration Surgery (ISHRS).

BACKGROUND: Because hair restoration surgery (HRS) has changed so significantly, the International Society of Hair Restoration Surgery (ISHRS) presents the recently developed Core Curriculum for Hair Restoration Surgery (CCHRS). Physician competence in HRS demands a sound understanding of all of the alternate pathologic causes of hair loss, as well as their risks and treatments. OBJECTIVE: The CCHRS defines the knowledge, didactic information, medical insights, and surgical techniques that are essential to physician competence in the correct diagnoses and treatment of hair loss problems, in a manner consistent with patient safety and sound esthetic results. The ISHRS hopes that all existing surgical and dermatology training programs that teach HRS procedures will find the CCHRS useful in developing their curriculum relative to HRS and that this will facilitate the development of a new standard of training within the profession. METHODS: Developed and reviewed by a committee of experienced hair restoration surgeons. RESULTS: The CCHRS clearly defines the diagnosis and treatment of hair loss as a multidimensional specialty requiring knowledge of several medical disciplines, including genetics, endocrinology, dermatology, and surgery. CONCLUSION: The ISHRS believes that the CCHRS is an important contribution to physician education in HRS and that a clearly defined core curriculum will facilitate achieving contemporary results and higher patient satisfaction.

The potential role of minoxidil in the hair transplantation setting.

BACKGROUND: Over the last decade surgical management of hair loss has become an increasingly popular and satisfying procedure for both men and women, as innovations in donor harvesting, graft size, and hairline design have resulted in consistently natural-appearing hair restoration. OBJECTIVE: In addition, a better understanding of the regulation of the hair-growth cycle has led to advances in the pharmacologic treatment of androgenetic alopecia. METHODS: Currently there are two U.S. Food and Drug Administration (FDA)-approved agents that promote hair regrowth: over-the-counter topical minoxidil solution for men and women and prescription oral finasteride tablets for men. In October 2001, a group of 11 international experts on hair loss and hair transplantation convened to review the physiology and effects of pharmacologic treatments of hair loss and to discuss the value of administering topical minoxidil therapy as an adjunct to hair transplantation. RESULTS: This article presents the key findings and consensus points among the participants, including their current use of pharmacologic treatments, strategies for optimal results both pre- and postsurgery, and the importance of realistic patient expectations and compliance. CONCLUSIONS: Based on the surgeons' clinical experience, the use of approved hair regrowth agents in hair transplant patients with viable but suboptimally functioning follicles in the region to be transplanted can increase hair density, speed regrowth in transplanted follicles, and complement the surgical result by slowing down or stopping further hair loss.
