Everyone's bangs seem grow faster than the rest of their hair, so I'll share some secrets to cutting a side bang.
Does anyone remember Nick Arojo from What Not To Wear? A few years back I took a class from him down in LA. What I'll be teaching you is similar to what he taught me. The only differences are the fact that he had us cut tiny sections at a time and we used a straight razor. The over all concept is the same though.
Step One: With dry hair, section out your bang area. You want your hair to be dry so you don't accidentally cut too much. Clip the rest of your hair out of the way.
