Injectable platelet-rich fibrin for treatment of female pattern hair loss.

This case series evaluated use of injectable platelet rich fibrin (termed i-PRF+) for the treatment of female pattern hair loss (FPHL). Eleven individuals underwent 3-monthly intradermal injections of i-PRF+ using a mesotherapy gun. The mean number of hair follicles containing hairs per unit area improved at 3- and 6-months follow-up (p <.001), and all participants had a negative hair pull test. Hair volume and thickness, and patient-reported outcome scores also improved at follow-up (p <.001). Adverse effects were minor and self-limited. A series of three i-PRF+ injection sessions were effective for the treatment of FPHL, as shown by improved hair analysis parameters and patient self-assessment scores. [ABSTRACT FROM AUTHOR]
