The Joico Defy Damage Sleepover Overnight Nourishing Treatment is a bedtime bond-strengthener that gets to work as you sleep.

With a fortifying formula, the hair mask aims to deliver soft, shiny, healthy-looking hair come morning. Protective lipids act as a shield from damage, while antioxidant-rich moringa seed oil lends shine and softness.

The brand’s SmartRelease Technology provides continuous release of rosehip oil, arginine and keratin to help support strong, resilient strands. This leave-in treatment protects and nourishes hair, complete with a unique vanilla and lavender fragrance.

Before going to sleep, apply a small amount to dry or towel-dried hair, avoiding the root area. Do not rinse.
