Does PRP actually work for hair loss?

PRP for hair loss has growing clinical evidence supporting its effectiveness, though it's not a miracle cure. Multiple studies show PRP can increase hair count, hair thickness, and the growth phase of the hair cycle. It works best for: androgenetic alopecia (male/female pattern hair loss) in early to moderate stages, where hair follicles are miniaturized but still alive. It's less effective for completely bald areas where follicles have died. A typical protocol involves 3 sessions spaced 4-6 weeks apart, then maintenance every 6-12 months. Results vary—about 70% of patients see measurable improvement. The best outcomes are in patients who combine PRP with other treatments like minoxidil or finasteride. For early thinning, PRP can be a worthwhile investment. For advanced hair loss with significant balding, a hair transplant will deliver more visible results. Set realistic expectations: PRP improves what you have rather than regrowing what's lost.
