19 years old, hair loss (pictures included)

[Lawrence1]

Hi guys. So I'm 19 and I noticed I was losing hair/thinning a little over a month ago. I started finasteride around 3 weeks ago, and my hairline seems to continue receding. I have really long hair so I'm not always sure.

I know finasteride takes a while before you start to see results, but is it normal for hair loss to continue for some time after starting the medication? I'm wondering if I should also start using rogaine? Does anyone have a norwood estimate? The thinning is not great, I have always been able to see my hair part though, if that makes a difference.

My last concern is that I am starting finasteride too early, as my facial hair is still developing, and I don't want it to stop developing or existing hairs to grow in slower. Does anyone have experience with this?
