learn Platelet-Rich Plasma
growth factors taken from your blood and injected into your scalp to stimulate hair
- Are Platelet results permanent, or does hair loss return once treatment stops? Hair loss typically returns after stopping PRP treatment, as effects are not permanent.
- How many Platelet sessions are usually needed before noticeable hair growth begins? Noticeable hair growth typically begins after 2 to 3 PRP sessions.
- What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
