More girlie input needed here.
No, actually I don't think there is, sorry to say. Why? because it's the blokes that will notice (And believe me, they WILL notice) and laugh at him behind his back.
The rules are this
Bald(ing)? Cut it short. The balder you get, the shorter you cut it. Nobody laughs at a bald bloke with a grade 1, but EVERYONE laughs at a comb over, or other attemps to cover it up.
Grey(ing)? Women can cover it because they can get away with it and everyone loves a new hair doo on a lady. Men can't get away with it becuse it smacks of desperation and mid-life crisis. EVERYONE notices. People WILL take the piss. I would!
I think if you're worried about the grey, the treatment is the same as for a bald bloke. Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Dems da rulz. 🙂
