A NEW TREATMENT FOR ANDROGENETIC ALOPECIA: PLATELET-RICH PLASMA INJECTIONS

Androgenic alopecia is a genetically determined and leads to a progressive hair loss of the vertex, affecting both men and women. It is related to an important psychological and social distress. Medical therapies include topical minoxidil, oral 5α-reductase inhibitors and oestroprogestative drugs with anti-androgen effects for women. The surgical option is autograft hair transplantation. Recently, phototherapy with low-level energy lasers became available. All these treatments may present adverse effects and their effectiveness is questionable. Subcutaneous injections of autologous platelet-rich plasma into the scalp represent an interesting alternative treatment for androgenetic alopecia, as monotherapy or as an adjuvant treatment. The methodology, the possible mechanisms of action and some initial clinical results of this treatment are presented.
