You realise that the majority of religions have women cover their hair to retain modesty. That's what that is about. The fact that women should have long hair and only let their husbands see it. This says they should do it only when praying, and that's why many orthodox Christians cover their hair when going to church. Jewish women, Hasidic Jews anyway, do it all the time as do Muslims.
On pubic hair, for me, it's a hygiene thing. I'm quite hairy, generally, and girls are juicy and stuff so it just seems cleaner to remove body hair. I like men to be a bit too hairy, but I like neat or shaven pubes.
