This may be a silly question but... When showering at the WG's place are you expected to wash your hair as well? I spend a good 20 mins in the morning combing and straightening my hair and I don't really wanna wreck it with a shower.
Absolutely mate.
I always wash it at least twice, then use conditioner. I make sure that I e-mail the girl first to ensure that she has my brand, otherwise I take my own, also it's important for a girl to state on her profile that she has a decent hair dryer, so many of them just don't bother.
A lot of girls will brush your hair and style it too if you ask them nicely, I find it a good prelude to sex.
