Nutrafol is one of those hair growth supplements that actually work. “I used to get highlights, and my hair incurred a ton of damage. It got to the point where I didn’t feel like my hair could grow any longer than my shoulders. I tried Nutrafol supplements as a sort of last-ditch effort, and I couldn’t believe how quickly my hair started growing—and how healthy it looked,” says ELLE beauty editor Katie Berohn. This set also includes the brand’s collagen powder, which features marine collagen peptides to provide hydration and other materials for strong, healthy hair.
