The verdict spread
Across 25 gurus, the overall verdict is 74% “mixed.”
What the gurus are saying
PRP has a loyal following for the under-eye area, where a few dermatologists say it plumps and refreshes thin skin without the filler look. The hair-loss picture is murkier: several gurus note real evidence for scalp use, but they warn results are hard to predict, sometimes do nothing, and the injections sting. Expect a short, mildly uncomfortable session, and treat any promised hair regrowth as a maybe rather than a guarantee.
