When it comes to tipping your hairdresser, there is no definitive answer. Ultimately, it is up to you to decide how much you want to tip, based on the level of service you received. If you are happy with your haircut and the overall experience, then a standard 15-20% gratuity would be appropriate. However, if you feel that the hairdresser went above and beyond or provided exceptional service, you may want to consider giving a larger tip.
