Topical Minoxidil Therapy for Hair Regrowth

The document reviewed the use of topical minoxidil for hair regrowth, focusing on its effects on hair follicles and scalp blood flow. Clinical trials showed varied results, with improved hair growth typically observed after 4 to 6 months of twice-daily application. Common side effects included mild scalp dryness and irritation. Minoxidil was recommended for patients with normal cardiovascular health, with monitoring of blood pressure and heart rate advised. While a new drug application was pending for treating androgenetic alopecia, no reliable treatment was found for alopecia areata, though minoxidil showed potential efficacy in some cases. The study highlighted the need for a better understanding of hair loss etiology to develop more effective treatments.
