Roles of Platelet-Rich Plasma in promation of hair follicle reconstitution
During the past several years, Platelet-Rich Plasma (PRP) has been introduced worldwide to medical treatment for its potential not only for speeding up the healing process both acute and chronic conditions such as in bone and joint injuries, but also for rejuvenating the skin.
Platelet-Rich Plasma (PRP) is from patient's own blood which contain 5-10 times greater of platelets and growth factors than normal. After a simple blood draw, blood will be spun down in a special centrifuge machine to separate and concentrate platelets and growth factors from other components.
A study from Nanfang Hospital, China, investigated the effects of Platelet-Rich Plasma (PRP) on hair follicle reconstitution in mice. The study has found that PRP shortened the time of hair formation from 20 days to 18 days and the number of new hair follicles was also significantly increased, in 10% PRP(344+/-27 hair follicles formed), compared with 0% PRP (288+/-35 hair follicles formed)
However, due to the inadequacy in evidence of PRP, further study is necessary. Therefore, current therapeutic treatments of androgenic-tic alopceia are still medication and hair transplantation.
