1 Get your hair cut at a salon? Tipping 15%-20% of the haircut cost is good, and maybe a little more around the holidays.  If I ever have to valet my car, I usually tip $2 to the valet driver when he or she brings my car back around.
Personally I find that the more work is done on my hair and the more it will cost me, the more tips I will leave. A simple haircut might lead to 10-12% (e.g. for a $40 haircut I usually leave $5 extra). On the other hand when my hairdresser has spent several hours on color, highlights and styling, I do tip her better because I know that she deserves it.
