PRP สำหรับผมร่วง (Platelet-Rich Plasma)

PRP (Platelet-Rich Plasma) for hair loss involves drawing the patient's blood, centrifuging it to concentrate platelets and growth factors, then injecting the resulting plasma into thinning areas of the scalp. The growth factors (PDGF, VEGF, EGF, and others) signal dormant hair follicles to re-enter the active growth phase, increase blood supply, and prolong the active hair cycle.

Treatment requires 3-4 initial sessions spaced 4 weeks apart, followed by quarterly maintenance. Best results are in patients with early androgenetic alopecia (male or female pattern hair loss) where follicles are miniaturized but not yet permanently lost. PRP works synergistically with finasteride (men) or spironolactone (women) and topical minoxidil — combination therapy outperforms PRP alone. Once hair follicles are completely lost (advanced Norwood VI-VII or Ludwig III), PRP cannot reverse the loss; hair transplant is the only option.
