This mask from Unwash works similarly to Kyn's, in the sense that you apply it to dry or damp hair in the evening, then rinse in the morning with water and style however you prefer. While you sleep, it helps nourish your hair and repair damage, hydrates parched locks, and even protects your color. You can braid your hair to lock the product in or apply the hair wrap that's included with your purchase.
The next time you're meandering in the aisles of Target (as we all do...), head on over the hair care section and pick yourself up a tub of this overnight dry treatment mask from The Mane Choice. As the name implies, it's made with prickly pear extract, which is high in fatty acids that help hydrate and nourish your hair. It's also formulated with silk amino acids to further moisturize and repair. It's meant to be applied to dry hair, then can sit for up to 12 hours before rinsing and styling.
For our ultra-splurge-y pick, we nominate this overnight hair repair mask from luxury hair care brand Sachajuan. It's a water-based gel treatment loaded with trace elements that's meant to be applied before going to bed and then rinsed out in the morning. While you sleep, it helps restore elasticity and strength for shinier, healthier, more youthful-looking hair.
