"Nobody has time to sleep," hairstylist Anh Co Tran jokes. (He's the celeb hairstylist behind some of our favorite trends cuts , and techniques; L'Oréal Professionnel ambassador; and co-owner of L.A. "It" salon Ramirez|Tran .) "There are so many shows in such a short amount of time, there's hardly any down time.
