I find the forced haircut scenario somewhat appealing especially if carried out by a female.
I've done enforced body hair removal before and found it to be fun but also humiliating and embarrassing (and a lot of work). Trying to keep my shaved body hidden takes some doing and concentrates my mind on how those areas might get exposed to others by accident and seeing it doesn't or seeing it does in the right circumstances.
I guess an enforced hair cut would much harder to hide and be far more embarrassing.
