Minoxidil（Cat No.:A000597）, is a medication primarily used to treat male and female pattern baldness (androgenetic alopecia). It is available in topical form as a solution or foam and is applied directly to the scalp. Minoxidil works by promoting hair growth and preventing hair loss by dilating blood vessels, increasing blood flow to hair follicles, and potentially prolonging the anagen (growth) phase of hair. While it can slow hair loss and promote regrowth in some individuals, its effectiveness varies from person to person. Minoxidil has been a popular over-the-counter treatment for hair loss and is available in various brand-name products.
