I think that salons are always offering hairdressing jobs because a great hairdresser could bring in a lot of income for a salon. Also a lot of hairdressers also come with their own clientle and have to pay rental fees for their station so the salon owner does not have to pay much money up front.
I think that it is important that the hairstylist know how to work with curly or courser hair because this type of hair has to be cut differently than straight hair. I have curly hair and always have to cut my hair in long layers because when my hair dries it will tend to shrink upward and look shorter.
The best hairstylist that I had was able to layer my hair in such a fashion that the excess weight was completely removed and my hair looked fantastic.
