Platelet-rich plasma for hair restoration¶

Abstract

Hair loss is treated with a wide range of clinical therapies including low-level laser light therapy as well as two FDA-approved medications: topical minoxidil and oral finasteride. Surgical options include follicular unit transplant (FUT) and follicular unit extraction (FUE) techniques, which are outpatient procedures with excellent outcomes. In addition to these existing medical and surgical options, platelet-rich plasma (PRP) is a relatively new, minimally invasive, office-based procedure used to treat hair loss, typically secondary to androgenic alopecia (AGA). PRP consists of growth factors extracted from autologous blood obtained by venipuncture. This concentrated mix of growth factors is injected into areas of hair loss, stimulating hair regrowth.
