the toothy thinning razor/scissor "texturizes" your hair towards the ends of the hairs. when your barber does a razor cut, he "texturizes" or thins your hairs out from the roots and upwards. overall the razor cut is superior because your hair gets thinned out more. any real barber that is advertised as a barber should know what you're talking about. plus, you shouldn't be getting your haircut at a salon anyway. you're a man. go to a barber.
I was under the impression that you had to go to a salon if you wanted anything other than a regular cut?
