I know one thing. When I leave western (or lebanese male) hairdresser and when I leave asian hairdresser I look completely different .
Yes, they do "the same job" and even same movements: they shampoo my hair, they take scissors, they make haircut, then they style my hair with the blow dryer... but the result is dramatically different..
And yes, to have a great look, I have to pay twice as much to the western hairdresser, which i don't mind..
I think it explains a lot..
