Topical finasteride with oral finasteride

[Dutch_Dude]

So I was reading about many different types of topical finasteride. Is there a preference among forum members for a particular formula? Also, is it important to use the brand name? I know that some people are still a little skeptical about generic oral finasteride. And last but not least, is it effective to use in conjunction with oral finasteride, especially for the hairline?
