Topical treatments question

[Dutch_Dude]

So I’ve been using Proscar since 2010 with pretty good success. I’ve been able to maintain most of my hair. However, I was wondering whether more could be done for the hairline region.

So is it a good idea to add a finasteride or dutasteride topical to oral finasteride? If so, should it also be Proscar? I’ve heard bad stories about people going on generics. Where do most people order theirs from? I’ve been seeing some commercials for it on social media but I don’t know whether these are trustworthy.

Any advice/suggestion would be appreciated.
