New in Sealed Tube. “We’d say this hair mask is magic, but its blend of keratin, algae, coconut oil, and shea butter is rooted in science. The mix of tried-and-true reparative and hydrating ingredients helps revive hair that’s been blow-dried, flatironed, or bleached. You could use it as a 15-minute treatment, but you’ll appreciate how it works fast too. After just three to five minutes in the shower, one of our editors lets her hair air-dry and it basically fakes a blowout that holds up for the rest of the day.”
