Follicular Unit Megasessions and Platelet Growth Factors

In a 2013 study, the document discussed the use of follicular unit megasessions in hair transplantation, where 500 to 1500 units were harvested and implanted, with results visible after 8 to 12 months for men and 12 to 14 months for women. The study also examined the effects of autologous platelet growth factors, with a specific study involving 20 male patients aged 22 to 54 years. This study found a 15.1% increase in follicular density in areas treated with platelet-rich plasma (PRP) compared to control areas, with improvements ranging from 3% to 52% among patients. The document concluded that autologous platelet growth factors could enhance capillary density and represent a significant advancement in hair transplantation, especially for patients with low density and fine hair in the donor area, and recommended further evaluation through a double-blind test.
