$20 plus a $10 tip+ $30. That has actually come down over the years. I'd be curious to see what a $400 haircut on me looked like. The main element making it worth those sums is if the stylist not only looks at how your hair grows and lies, but also has a critical eye for what would work best with your head, make you look as good as you can (or better?). Federer has always had a bit of insecurity about his looks and he's right. For him, a good haircut really does make him look much better. It matters more for some than others. Still, I'd fork over $400 once and if I thought it looked terrific, I'd immediately get my $30 guy to look at it closely and photo it for future reference. Unless I earned $70 million/year. Like Federer.
