How does Rogaine make your hair start growing again?

Actually, no one’s really sure how Rogaine makes your hair start growing again.

What we do know is that it can’t make hair suddenly start growing after years of not growing.

Because of this, it’s most effective on people who have just begun to notice a little bit of thinning. On most people, after about two weeks some hair starts to grow.

But if the treatment is stopped, the hair stops, too.
