PRP for Hair Loss in 2026: Who It Helps and Who It Doesn't

PRP for androgenetic alopecia has accumulated reasonable supportive data for early-stage thinning, particularly when follicles are miniaturizing rather than absent. The effect size in most studies is modest and requires maintenance.

Selection is what drives outcomes. Patients within the first few years of noticeable thinning, with visible vellus hairs in the affected zone, tend to respond. Patients with long-standing smooth scalp typically do not, and we say so rather than sell a series.

PRP is also not a replacement for standard therapy. Minoxidil, finasteride where appropriate, nutritional and thyroid workup, and surgical referral all remain part of the conversation.
