It depends on how it looks on them. Some men look fine with thinning hair ....
I don't think every man who is balding would look better with a shaved head.
With hair, without hair, a little hair -- never made a difference to me.
No to comb overs. I don't mind close cut balding, kinda sexy ;) As JustPlainBarb says, not everyone look good completely shaven.
roots are strong..
Bald looks way better. The second that hairline starts receding they should just off it.
Billy Zane got it right.
