Comparison of Efficacy of Platelet-Rich Plasma With and Without Topical Minoxidil for Hair Growth in Patients With Androgenetic Alopecia: A Prospective Study

The study conducted at Saveetha Dental College and Hospital involved 40 participants with androgenetic alopecia, divided into two groups. One group received platelet-rich plasma (PRP) therapy alone, while the other received PRP therapy combined with topical minoxidil. The results showed that the group receiving PRP with minoxidil had a significantly higher mean hair shaft diameter and hair quantity at the two and three-month postoperative periods compared to the PRP-only group. The study concluded that PRP therapy combined with topical minoxidil is a better treatment option for improving both hair quality and quantity compared to PRP therapy alone. The study acknowledges a short follow-up period as a limitation and recommends further studies with a larger sample size and longer follow-up period for more accurate results.
