BACKGROUND: Alopecia significantly affects the mental health and social relationship of women since childbearing age, highlighting the need for a safe, effective, and convenient treatment.
METHODS: The authors have conducted a prospective self-controlled trial involving 15 female patients at childbearing age with alopecia. These patients received a subcutaneous scalp injection of platelet-rich plasma once every 4 weeks for 3 treatments in total. Outcome measurements were included below: changes in hair density (hair/cm 2 ), hair follicle density (hair follicle/cm 2 ), and overall photographic assessment (improved or not) at 4, 12, and 24 weeks right after the first treatment.
RESULTS: Comparing the photographs taken before and after the intervention, 67% of patients' hair density increased from 151 ± 39.82 hairs/cm 2 (preintervention) to 170.96 ± 37.14 hairs/cm 2 (at 24-week follow-up), representing an approximate increase of 19 hairs/cm 2 . Meanwhile, hair follicle density increased by approximately 15 follicles/cm 2 after 24 weeks since the first treatment, rising from 151.04 ± 41.99 follicles/cm 2 to 166.72 ± 37.13 follicles/cm 2 . The primary adverse reactions observed were local swelling and pain due to injections.
CONCLUSION: Local injection of nonactivated platelet-rich plasma with low leukocytes concentration could be an effective strategy to alleviate alopecia symptoms in female patients.
