Minoxidil is a medication that is used to promote hair growth and treat hair loss. It is available in both topical and oral forms. How To apply minoxidil, first clean your scalp and dry it thoroughly. Then, take the prescribed amount of minoxidil and apply it directly to the scalp in the areas where hair growth is desired. Massage the minoxidil into the scalp until it is fully absorbed. It is important to use minoxidil as directed by a healthcare professional, as overuse or misuse can cause unwanted side effects. Additionally, it is important to continue using minoxidil for at least four months to see significant results. Additionally, it has received approval from the Food and Drug Administration for hair loss and the associated symptoms. Along with the dry scalp area where it is typically administered, minoxidil solution can also be used on wet hair.
