Overnight Hair Treatment That Repairs and Strengthens While You Sleep
Joico Defy Damage Sleepover is a leave-in overnight treatment that turns your bedtime routine into a hair repair session. While you sleep, the formula gets to work strengthening, nourishing and protecting your hair so that by morning it feels noticeably softer, shinier and healthier. At 100ml it is a brilliant size for travel as well as everyday use on the bedside table, and the calming vanilla and lavender fragrance makes it a genuinely pleasant addition to a night-time routine.
Protective Lipids and Moringa Seed Oil for Overnight Repair
The formula works on two levels to protect and nourish the hair overnight. Protective lipids form a shield around each strand, defending against the friction and stress that can cause damage during sleep — something most people do not think about but which can genuinely weaken hair over time. Antioxidant-rich Moringa Seed Oil works alongside the lipids to enhance shine and smoothness, so you wake up with hair that looks polished and healthy rather than rough and tangled.
SmartRelease Technology Working Through the Night
Powered by Joico's SmartRelease Technology, the Sleepover treatment continuously releases Rosehip Oil, Arginine and Keratin into the hair throughout the night. Arginine and Keratin strengthen and rebuild the hair fibre from within, while Rosehip Oil delivers deep moisture and resilience. Because the product is left on overnight rather than rinsed away after a few minutes, the ingredients have far longer to absorb and work than a standard rinse-off treatment — meaning results you can actually feel the next morning.
How to Use Joico Defy Damage Sleepover
Apply a small amount to clean, dry or damp hair before bed, focusing on mid-lengths and ends. There is no need to rinse — simply leave it in overnight and style as normal in the morning. For best results, use as part of the wider Defy Damage routine alongside the Protective Shampoo and Conditioner.
