How I think about detectability goes up and down. Sometimes I don't care, if the hair looks awesome, I'm inlcined to not care if a girl feels something. If it boils down to it, I'll just tell her I have alopecia. If she doesn't like it, then screw her lol. Another part of me, fears that anxiety of her feeling something. So its a toss up, but showing insecuirty isn't a manly quality. In this context I mean, if she sees you are anxious about wearing...then its not attractive. Thats why bald guys, well all the ones I know HAVE to be confident, there are no ifs and buts...to attract women, even if they are faking it, they don't show it infront of women. There is no 100% chance of her not feeling something, so I dunno, maybe its better off me going for a larger size and having some awesome styles while I can get away with it for my age.
