Given substantial advances in hair regrowth research and platelet-rich plasma (PRP) science, a review of currently used systems and results is informative for physicians using a biologics approach to hair restoration. Overall positive clinical response to the use of PRP in androgenetic and alopecia areata patients is observed. The effects on hair density, count, and thickness were demonstrated through multiple clinical trials. Use as an adjunct to hair transplantation and with other technologies is also described. When compared with traditional oral/topical treatments, the lack of identifiable complications and convenience of treatment provide a positive outlook for future use and investigation.
