Will finasteride reverse my miniaturizing hairline?

Hey I’m 19 and In thinning around the hairline I’m now on 0.5g finasteride since 2 weeks and me question is will finasteride thicken these fine hairs on the hairline or do I need to Derma roll?

Provided you are not talking about the loss of your juvenile hairline in developing a maturing hairline, a 19 year old with early genetic Class 3 type hair loss may reverse the process on finasteride. Finasteride will not help you hold on to a juvenile hairline or bring it back.
