From anti-aging haircare to the perfect hair cut, Hollywood divas are always in on the latest ways to have healthy, youthful-looking locks.

And now a hair color effect called OMBRE is steadily becoming a celebrity and city girl favorite. "Ombre" literally means gradation in French, which refers to the dark-to-light fade of color that is used in the technique. Instead of color that starts at the root, darker roots blend into a lightened mid-shaft and end.

It's a beachier, more natural looking version of the enduring "visible root" trend.
