If i'm tipping my hairdresser for the holidays, would the amount be the usual tip amount plus gift amount, or just gift amount?

tomorrow i’m going to hairdresser. usually for some reason my recent years’ appointments have not been in december so i have not done the holiday tip thing with her. i am wondering, if my haircolor costs $50, and i usually tip her $10 when she does it, should i tip her only gift amount (and i don’t know what that amount should be) or should i tip her the usual $10 plus gift amount on top of that?
