Minoxidil dilates blood vessels, and is sometimes called a "potassium channel opener." In the brand name Rogaine, it is FDA approved to stimulate regrowth and thicken hairs. Minoxidil is applied topically to the scalp, and has been shown to promote hair growth in about 25% of men and women, though it may take several months to work. New hair is usually thinner and lighter, like baby hair, and grows mostly on the top of the head, not at the hairline. Its effects may fade with time. Skin irritation is the most commonly reported side effect. Dizziness and increased heart rate have also been reported, but rarely.
