The use of Minoxidil can regrow hair. Minoxidil is primarily used to treat androgenetic alopecia and baldness. It is a peripheral vasodilator that stimulates hair growth in patients with androgenetic alopecia and pemphigus vulgaris when used topically for long periods of time. The exact mechanism of hair growth is not clear, and may be related to dilating subcutaneous blood vessels and improving microcirculation around hair follicles. Therefore, the use of Minoxidil can regrow hair. However, adverse reactions such as burning pain, neuritis, dizziness, syncope, vertigo, edema and chest pain may occur after the use of this drug, and it is recommended to stop the drug in time and seek medical attention. It is contraindicated for those who are allergic to Minoxidil or any of the other components of the product. Patients are advised to use Minoxidil under medical supervision and should not use it privately.
