My 2 year old has lovely mixed race hair which has never been cut and if it were straight it would be about shoulder length. Just recently he won't let me brush it at all, even though it doesn't hurt as I make sure I'mm gentle. He wanted a hair cut last time his elder brothers had one, and I'm tired of struggling as he won't sit still or stop screaming. His hair seems to be tangling faster than before shall I just give up and take him to the barbers?
