TLDR PRP injections effectively improve hair growth in androgenic alopecia.

The study evaluated the effectiveness of platelet-rich plasma (PRP) injections in treating androgenic alopecia in 18 patients, consisting of 7 women and 9 men. Patients received three PRP injections at 21-day intervals, and results were assessed through clinical photographs, dermoscopy, and questionnaires. Women reported an average improvement of 42.85%, while external observers noted a 35.71% improvement. Men reported a 25.55% improvement, with observers noting an 18.88% improvement. Dermoscopy showed hair thickening, improved circulation, and increased follicle numbers. The study concluded that PRP injections provided an effective and satisfactory response in treating androgenic alopecia.
