This mod slightly improves barbers by adding a hair clipper to their hands (yes, they will no longer cut with their bare hands), as well as animation while waiting, which makes them more lively.
Cool mod, I always asked how the hairdressers cut CJ's hair, it had the sound of a hair clipper but the hair clipper didn't exist, in GTA 5 the hairdressers appear with scissors in barbershops.
