Platelet Rich Plasma therapy, most commonly known as PRP, is an autologous therapy that has the potential to promote healing including hair loss. A small amount of the patient’s blood is processed to concentrate the platelets and reinjected in the areas affected by hair loss. The growth factors in PRP are thought to help with healing and promote the growth of hair follicles. PRP can be used to treat hair loss in both men and women.
Platelet-rich plasma (PRP) is an autologous preparation of platelets in concentrated plasma. The normal platelet count range is 150,000–350,000 per µL of blood. In platelet-rich plasma, the RBC count is lowered to 5 while the platelet count is increased to 94% (three to eight-fold greater than normal).
In addition, it contains platelet derived growth factor (PDGF),vascular endothelial growth factor (VEGF),transforming growth factor (TGF) and other bioactive proteins that aid in wound healing and possibly hair growth.
PRP is ‘autologous’, meaning that it comes from the patient’s own body.
Growth factors in platelet rich plasma (PRP) have been used to facilitate wound healing. Recently, studies have suggested that PRP may also serve as a safe and effective treatment option for male and female pattern hair loss.
After collection PRP is placed into a syringe and reintroduced into the treatment site i.e., either the surgical site or an area of hair loss.
PRP therapy typically consists of three treatments in a 4–6 week period, with maintenance treatments every 4–6 months.
PRP treatment requires maintenance sessions every six to twelve months to continue producing positive results. Although PRP treatment has been shown to encourage hair growth and thicken hair in areas that have been treated, it will not prevent new bald areas from forming in untreated areas of the scalp. Response to PRP will differ between patients and it is not known how long the benefits will persist.
There were no major adverse effects such as scarring, progressive worsening, or infections after PRP. Notably, mild headache, tolerable and temporary pain during treatment, mild itching and desquamation, and transient edema may ocur.
