Abstract

BACKGROUND:

Recently, platelet-rich plasma (PRP) injection has been proposed as a potential adjuvant therapy to treat androgenetic alopecia.

AIMS:

Investigate the efficacy, tolerability, and clinical improvement of PRP for the treatment of female AGA.

PATIENTS/METHODS:

A total of 10 female patients affected by AGA and not responding to treatment with minoxidil and/or oral antiandrogens were enrolled. The clinical improvement was evaluated by pull test, global photographs, and Trichoscan at weeks 9, 12, and 24, and hair measurements were performed at baseline and 12 and 24 weeks after the first session.

RESULTS:

After 24 weeks, the median relative percentage change (%RC) for all the parameters of hair density was mostly positive. After 12 weeks, the medium hair diameter in frontal area showed a significant increase (%RD = 12.5, with P-value < .05), and after 24 weeks (%RD = 14.6, P-value < .05), the vellus relative change instead showed a decrease, especially in the front and the central area, while for the vertex, the decrease was mainly visible at the end (-6.6%). No adverse events were reported.

CONCLUSION:

Platelet-rich plasma injections have a positive therapeutic effect on hair density and hair diameter improvement.
