I am having my 'trial run' hair appt tomorrow. The package that I selected included the trial, facial, brow wax, make up and hair all at one price. I expect to tip the esthetician for the wax/facial/makeup seperately, but the trial hair and final hair will be by the same person. Do I tip her twice? What price do I base the tip off of? Small tip now, larger one day of? Please advise. Thank you
