Question: How Much Should I Tip When I Get My Haircut?
Answer: You tip a hairstylist and colorist just as you would a server in a restaurant: If the service is excellent, then you tip 20%, if the service is good 15%, and so on.
If there are several different people involved from assistants to the shampooer, it's standard to pay $3 to $5 to each individual who shampoos and/or blows out your hair. You may also ask your stylist who you should tip. After years of tipping everyone who touched my hair in my fancy NYC salon, I learned that my hairstylist actually tips her assistants from her own large tip that she gets because her prices are so high.
As for other beauty professions -- the same rule applies to your manicurist, your aesthetician and anyone who spends time making you look beautiful (at a cost). They get 15-20 percent as well.
