PRP Hair Restoration Many women suffer from hairloss, with androgenic alopecia being the most common cause. Conditions such as PCOS can exacerbate this. Unlike men who develop a receeding hair line, women start to notice a widening part and thinner hair as this condition progresses. Platelet-rich Plasma (PRP) is a fairly new, exciting, non-surgical option for natural hair restoration. PRP works by increasing cell proliferation, and promotes the transition from telogen to anagen phase in the hair cycle as well as prolongs anagen phase. To create thicker and more dense hair.
