DS was born with a lot of hair. He has lost the majority of it - especially where he has a big bald patch on the back of his head!! (very attractive!!) However, he has a strip of hair on top in the middle that would make for a superb moheican but is startin to look a bit silly - should I go over it with the clippers to make it the same legnth as the new hair growing in or is that just cruel??!!!
