I always cut the boys hair and don't get to crazy because:
A. I'm not a professional
2. The boys, mostly Vince hates getting his haircut
D. The boys could careless what their hair looks like at their age
I usually just go with the buzz because it's great for summers and it's quick and easy. Like I said, Vince usually hates getting his haircut but he did so much better this time! He even smiled beforehand.
Full disclosure: They always get to watch a show and get a treat after, but it works!
