This topic has come again in recent posts, as it does from time to time.  I'm not a parent so it's a little hard for me to know how I'd react to a son who wanted to shave his head.  The recent post about the 7-year-old seemed way too young to me, although in all likelihood that boy is probably sporting a buzz cut and not a razor shaved head.

I really don't think I'd have an problem at all with a 15 or 16 year old son who wanted to shave his head.  It is, after all, just a haircut.  I might even be willing to allow it at a slightly younger age, if the young man was mature enough to realize that hair does not grow back overnight, and if he didn't like the shaved head he would have to live with it until it grew back out -- and it could take quite a while to reach its previous length.

I really don't know what the appropriate cut-off age is, or if there even is one.  Maybe these decisions just need to be made on a case by case basis.  I'm interested in hearing the opinions of others, particularly those of you who are parents.

My 2 cents.  I have a son who is almost 2.  I also shaved my head in high school for sports because I didn't like the feel of matted hair under my helmets. 

No razor shaving until they have a need for it to shave their face too.  High school they get to choose.  Before that, case by case.  I think it comes down to the reason (sports, thinking it would look better, wanting the join the skin heads, etc) and the emotional maturity of the kid to deal with the results, even if that's only for a few months.

My brother and I would use clippers without a guard to shave our heads when were about 7 years old.  Where we lived it was super hot and we played sports, so our parents let us.  If I had a son, I wouldn't let them use a razor until high school.
