15 Seconds to Beautiful Hair

We got Hollywood hair guru Robert Vetica (Mariah and J. Lo sing his praises) to share—in his own words—his best advice on everything from cuts to color. Follow his words of wisdom for spotlight-stealing strands!

1. Don't over-wash your hair
Ever wonder why women in Europe or Asia, or for that matter anywhere outside the United States, have such amazingly healthy-looking hair? They do not, I repeat, do not wash their hair every day. They go at least two or three days between washes, letting their natural scalp oils coat and nourish their strands. Now I know there are some women out there saying, "You're absolutely nuts. I go to the gym, run, do yoga, and sweat, so my hair has to be washed every day." Take it from me, it doesn't. Instead, just give your hair a good rinse with water and follow with minimal product to avoid buildup. I promise, soon you'll find that you have a head full of lustrous, healthy hair.

2. Learn to love leave-ins
If you give your hair a break from shampoo, it will dry out less and won't require much conditioner. That said, I am sort of addicted to leavein conditioner and recommend massaging one into damp hair on days you do wash. It gives your do just the right amount of moisture it needs to stay soft and adds a bit of texture and hold too.

3. Stock up on dry shampoo
This is a permanent fixture in my styling case because it has so many uses. For example, you can dust it on to absorb excess oil when you've gone too long between washes. Or you can use it to give fine hair some oomph—just apply it at your roots all over your head and brush through.
