I have been giving my DS (22) and DH hair cuts for a few years now without problems. Nothing fancy just a #2 all over. Did DS just now and noticed a few ends. I forgot to put the #2 guard back on he now has a patch at the front shorter than the rest.
Many years ago DH used to go to a barber who favoured the comb-over. I used to protest loudly that his receding hairline would look much better if all his hair was cut short like Sean Connery as he was beginning to look like Arthur Scargill
DH didn't agree with me so one night I waited until he was fast asleep and cut the dratted long bits off. DH refused to change barbers and hid his spiky new hairstyle under a tweed cap so instead of Arthur Scargill I ended up with Fred Dibnah.
Merlot Either very brave or very foolhardy of you!
Comb overs do look worse that bald patches. I don't mind bald patches at all. My DH used wear his hair the same style as his dad until I bullied him into having it close cropped. Its white now but he looks so much younger.
