Why our stylists rate it
From the Partners Hair team
Joico Defy Damage Sleepover is a no-rinse overnight nourishing treatment for all hair types, especially damaged, over-processed and colour-treated hair. Part of the Joico Defy Damage range. SmartRelease Technology works while you sleep — continuously releasing rosehip oil, arginine and keratin to rebuild bonds, soften, reduce split ends and wake up to visibly healthier hair.

Best for: all hair types needing an effortless overnight bond-building and nourishing treatment; damaged or colour-treated hair wanting morning softness and shine without additional effort.
Less suited to: a styling hold product; a pre-styling heat protectant (use Defy Damage Protective Shield); immediate daytime conditioning.

Key actives:
- SmartRelease Technology (Rosehip Oil, Arginine & Keratin) — liposome delivery system that continuously releases bond-repairing, strengthening and protective ingredients overnight
- Arginine — smart-bonding amino acid; rebuilds broken bonds while you sleep
- Moringa Seed Oil — antioxidants, Vitamins A and E; nourishes and adds softness
- Rosehip Oil — essential fatty acids; conditions and adds shine

Benefits:
- Nourishes, strengthens and rebuilds bonds while you sleep
- Reduces appearance of split ends
- Wakes up to softer, shinier, visibly healthier hair
- No rinse — apply before bed, style in the morning
