Platelet-Rich Plasma Growth Factor Concentrated Spray (Keratogrow®) as a Potential Treatment for Androgenic Alopecia.

Abstract

The objective is to investigate the safety and clinical efficacy of Autologous Platelet Rich Plasma Concentrated Spray (Keratogrow®), for hair loss. Autologous -PRP spray, prepared from a small volume of blood, was applied on the selected patients' scalps at least twice daily. Three months treatments were given for each patient. The effectiveness of the medication was measured by changes in hair regrowth after 3 months determined by physical exam and digital photography. At the end of the 3 cycles of treatment, the patients presented clinical improvement in the mean number of hairs, with a mean increase of hairs in the target area, and a mean increase in total hair density compared with baseline values.
