Defy Damage Sleepover is a leave-in treatment that nourishes and strengthens hair overnight, leaving hair softer, shinier and visibly healthier when you wake up. It preserves more than 85% of color vibrancy, reduces the appearance of split ends, and instantly softens and smooths while protecting against pollution.
Apply a few pumps evenly to dry or towel-dried hair before bed, avoiding the roots, then leave on overnight without rinsing. Repeat 2 to 3 times a week or as needed.
