well with 2 friends who are great hairdresser/shop owners I am privvy to what the actual costs of their products are compared to what the charges are for the services i.e. a haircolor treatment. They also build into their cost a reasonable wage for their services. Tipping, as for ANY profession/job, is a courtesy, not a requirement. Wait staff is paid just over $3/hour. I know that that is not true for hairdressers. just mho. I don't want to see another tipping battle on the boards! lol
