You can pile on all the anti-aging skin care products you want, but when it comes to looking 10 years younger than your actual age, it's your hair that makes all the difference.  Your hair is one of the first things people notice when they meet you. 

 

And I'm not just talking about grays. In fact, gray hair can be youthful when cut and styled the right way. Meanwhile, even if you have really pretty brown, blonde, or red color, a bad haircut will age you.
