Yeah you should be able to find a beauty supply store open today unless you live in a town of 200 people. Get the girls to help you. Tell them what your doing and if they look at you funny, don't worry. Who are the going to tell? Someone the other day said that the girls wouldn't help them because they didn't want them doing back to back treatments so get them to help you with the color match first then ask about bleaching. I give 85% chance of passing or higher.
