Topical minoxidil therapy for hair regrowth.

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