How does minoxidil (Rogaine) work?

ANSWER

Minoxidil (Rogaine) is a liquid or foam that you rub into your scalp. Studies show it can help hair grow, but it may also help you hold on to the strands you already have.

The earlier you start using minoxidil, the more likely it is to help. You have to use it for at least 4 months, and possibly for up to a year, before you can see if it’s working.

You apply the medicine twice a day to dry hair. Applicators make the process less messy. The main side effect is scalp irritation.
