Tipping is a custom that allows you to express appreciation for a job well done. But when it comes to salon, spa, and nail services, it can be hard to decide how much to tip. And while tipping is at your discretion, there are a few suggestions on amounts to give. For your body sugaring practitioner, hairstylist, colorist, aesthetician, massage therapist, nail tech, or any other main service provider, the standard tip is 15 to 20 percent of the bill before taxes. For more specialized services (like coloring or Brazilians) or if your beauty professional went above and beyond, think about tipping more than 20 percent as an added gesture. And for the holidays, you should never feel obligated to give something extra for the holidays, but a handwritten note, handmade gift, or additional cash tip is a meaningful expression of your gratitude.While it has been standard practice not to tip the salon owner, this "rule" has become a bit old-fashioned. For a job well done, it's always a kind gesture to tip. If you're using a coupon or online discount, tip based on what the bill would have been.
