Ecaille has been buzzing in the haircolor world as of late, and it's not hard to see why.

Bold, bright and unnatural colors are starting to decrease in popularity as more natural hues resurface. The color has been worn by Blake Lively, Jessica Alba, Chrissy Teigen and Khloe Kardashian, among others.
"This is a technique that really has to be customized for each specific client, and that includes the formulas as well as the placement pattern," Madame Claude says. "The accent pieces and punctuation of light are crucial to making this tortoiseshell effect flattering."
