Never Know How Much to Tip?

The amounts are up to you, but here's a salon cheat sheet: Give $5 to the assistant who shampooed your hair and a tip equal to 15 percent to 20 percent of the total bill before tax to each person who worked on it, from the cutter and colorist to the person who did the blowout and styling. If the owner provided the service, "don't feel obligated to tip," says salon owner Paul Labrecque. Also handy: the Tipping Tips app ($1; iPhone) with a calculator, plus global gratuity information.
