I was getting a trim at the local old school barbershop, with a twirling barber pole outside. The barbers there were deriding places like Fantastic Sam. They claimed that those people didn't know how to cut hair, because they were 'cosemotolgists.' What is the diff between the costemologists and barbers, and which one would be better? Is it even worthwhile to go to a salon if I have really thick, coarse hair? Think of a brillo brush. Can a better hair person make that big of a difference with hair like this?
