If you have some gel or something in your hair or if it is styled really nice (or both) women tend to stay away.

If you are pre sex sitting on the couch and she starts to touch your hair and you move your head away from her touch they usually get the picture and steer clear of your locks.

If you continue with her, sooner or later she is going to know - sometimes it takes a few months, sometimes they don't admit they've figured it out.

When "busted" I say, "Oh, I thought you knew, it's somewhat obvious but I don't really talk about it", I play it down BUT I still make it clear that it's not something I like to make public or make a big deal about it - you don't want her telling everyone publicly, "Hey look at Bob's hair it's fake it looks so real doesn't it?"

When asked "why wear?" you can always bring up makeup or boob jobs or whatever women do but tread lightly. I usually stay away from that and just say "I have most of my hair but it was a little thin so with this I get thicker hair, more flexibility I just really like it"

Lastly I never, ever, ever let anyone see me without hair except other TL wearers at a convention or the girl that takes my videos. I just don't want anyone to have that image of me, hairless in their minds - it's not necessary.
