I am finally going to get a hair cut, and also decided to go for highlights. I made an appointment at a "higher end" salon in my area that has really good reviews. I am going with second level stylists (out of 4 levels) and the color and cut is going to cost about $240 (maybe a little more). I use to always leave a 20% tip for my highlights/color...but that was when I went to the same girl for a long time and it was $120 for highlights/cut/style (this was in another state-a few years ago). Honestly, I feel uncomfortable leaving a $50+ tip, even if they do a great job. What is an acceptable amount to leave as a tip? Would something like $20/$30 be completely offensive?
