Scalp Vascularization as a Marker of Topical Minoxidil Treatment Efficacy in Patients with Androgenetic Alopecia

The study investigated the impact of scalp vascularization on the efficacy of topical 5% minoxidil treatment in 76 patients with female pattern hair loss (FPHL). Patients were divided into groups with rich and poor scalp vasculature and treated with minoxidil for at least 6 months. Results showed a significant increase in total hair count and a decrease in single hair per follicle in 50.67% of patients. Overall, 57.33% of patients experienced an increase in total hair count, and 68% had no drops in total count. The study concluded that patients responded equally well to minoxidil treatment regardless of scalp vascularization.
