DH has grown his hair down below his shoulders, it is very thin, dry, straggly, greying with loads of split ends and it accentuates the bald patch on top so is very unflattering. Until growing it out he has always had extremely short hair and couldnt even go 2 months without a trim. Personally I dont judge by appearance but it looks such poor condition and unkempt (despite daily washing which is likely making it worse) which other people are judging. We have 4 teenagers and I am also concerned that they are embarrassed about his appearance (more so than is usual for teens). I have tried to discuss it and he said if they werent bullied about this then it would be something else and that wouldnt make him change his hairstyle. There appears to be no compromise.
