Remember the golden rule: "You should tip 20% on the entire service cost, not per individual," says Schweitzer.

Generally, you should tip a hairdresser 20 percent if you're happy with all aspects of your service, says Hodges. So whether you get a basic trim, a blowout, or a major color change (like the super-trendy blue hair you've been saving on IG), 20 percent is a rule of thumb.

How much should you tip your hairdresser? We asked three etiquette experts, two salon professionals and a certified financial planner. Most of these experts suggest leaving 15% to 20%, depending on the service and your satisfaction. Going with 20% is nice for the stylist and you because that math is pretty simple.

Average haircut price The average cost of a haircut is $15 to $75, depending on the location, salon type, and the stylist's experience. Your hair's length and texture may also affect the haircut price. The average price for a women's haircut is $45 to $75, while men's haircut prices range from $25 to $50.
