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.
With proper tipping etiquette, the percentages of your tips do not change because of the cost of the service. Let's take a hair salon, for example. Of course, you can always tip on the lower end of 10-20%. But if you are going to go to a more expensive salon, then it is assumed that you can afford $120 plus tip.
