16 Products That Work Wonders on Dry, Damaged Hair

K18 Leave-In Repair Hair Mask Treatment ($29)

I hate to choose favorites, but K18 should truly be everyone's go-to brand for repairing damaged hair. The biotech treatment restores strength, softness, smoothness, and bounce with every application, so I use it every time I wash my hair after towel-drying. The vegan and cruelty-free formula is highly concentrated, so you really don't need a lot and it works in just four minutes. As our PS senior beauty editor writes in her K18 Hair Leave-In Molecular Repair Hair Mask review, "It gives me bounce and movement and miraculously doesn't weigh down my fine hair."
