Also recommend Aveda, for girls. NOT for guys, unless it's special event, then pay 200 for a top notch professional.
Grad student who did mine divulged that she mostly practiced on girls. Pretty sure she had no idea what to do with my hair at all as every step was first instructed by the educator, who is very good. I'm probably her first.
Unfortunately...
the other mistakes (all male hair related) were insignificant.
all the girls getting their hair cut seem to have expert treatment and stylists who knows what they were doing.
if you are a guy, MUST go with a full head of hair, or you may end up bald, at least on the sides. The longer the hair, the more mistakes to recover from.
Aveda needs to provide their students more practice on doing guy hair. Hair work for girls looked fabulous to me from the many that came and went while I was there. Perhaps a volunteer program for free haircut for guys will give the students there the needed practice.
