Brand new factory sealed. Why you'll love it: This innovative hair mask was made in collaboration with hairstylist Chris Appleton, who is known for creating his super-shiny signature "glass hair" for celebrities like J.Lo, Kim Kardashian, and Ariana Grande. The mask was dreamed up to deliver the same level of glossy shiny at home and "it does not disappoint," says Allure's Paige Stables, who tested the in-shower mask on her bleached blonde, heavily hot tool-damaged hair. "My hair was given new life and felt like it was spun into silk-shiny, smooth, and voluminous." How you'll use it: After shampooing, smooth a golf ball-size dollop of this gel-like mask from roots to ends and rinse it out after five minutes.
