how much to tip a hairdresser at christmas

*laughs* Well, that's a good question! In the US, the standard tip for a hairdresser is usually 15% of the total cost of the service. However, if you're really satisfied with your hairdresser, you can always tip a bit more to show your appreciation. During the holiday season, it's also common to tip a bit extra to show your gratitude for their work. So, to answer your question, I'd say a good tip for a hairdresser at Christmas would be around 20-25%.
