It's a fact that women pay more for haircuts and hairstyles than men do. That's understandable; for the main part, they have more hair! When you're an international pop celebrity and a style icon, you'll inevitably spend more money staying on-trend and well-presented than most people do. We're not sure most celebrities take things quite as far as Rihanna has over the years, though.
There isn't a hairstyle Rihanna hasn't had, other than shaving her head (and we won't rule that out as a future look). From weaves to perms to extensions, she's tried and discarded them all. Her most expensive look is believed to have cost her one million dollars. We're not immediately sure which style it was - or how it could possibly have cost her so much - but we know it happened, and that's pretty incredible.
