platelet-rich plasma PRP androgenetic alopecia mechanical PRP injections controlled PRP injections medical injector gun

Studysummary In this study, 23 patients with androgenetic alopecia were treated with non-activated autologous platelet-rich plasma (A-PRP) administered through interfollicular injections, but the abstract provides no results of the treatment's effectiveness. Our plain-language summary of this paper — not a Tressless recommendation.

A study from 5 years ago found that both mechanical and controlled PRP injections can be effective in promoting hair growth in patients with androgenetic alopecia. The study involved injecting PRP at a depth of 5mm using a medical injector gun, with three treatment sessions performed for each patient at 30-day intervals. The study suggests that using a gun to inject PRP can effectively treat hair loss in patients who are sensitive to pain and do not require anesthesia. The authors recommend further clinical trials using mechanical injection systems.
