Topical liposomal finasteride vs oral finasteride

hello doc, is oral finasteride more effective than topical one? as i wanna switch from topical to oral and topical isn’t showing much results, also my doctor is saying as topical has various factors like skin ph humidity etc issues of absorption, oral is more reliable.  What do you think, should i start oral and be more optimistic about it?

I believe that it is more effective as the oral impacts all of the miniaturized hairs you don’t see while the topical only works where you apply it, that is, if it is the liposomal topical finasteride
