I'm curious about who is recommended for hair loss treatments.

Hello. I visited my boyfriend's house last weekend and found out that he is taking hair loss medication. When I asked him about it, he said that he doesn't actually have hair loss, but he is taking it along with his younger sibling as a preventative measure. I'm worried too, so I looked up some information on the subject and decided to leave a post on Maypure.

First of all, my boyfriend naturally has thin hair with low density. In this case, would getting hair loss treatment be helpful? He has a rather broad forehead, so I am wondering if the treatment would also help with his hairline. Would it actually be beneficial to get the treatment before he starts losing a lot of hair? I suppose it would be difficult to see a hair growth effect, right?
