The Moroccanoil Overnight Hydrating Leave-In Hair Mask Treatment Serum is a brand new overnight hair mask featuring supercharged hyaluronic acid and vegan snail mucin that leaves hair four times more hydrated. Keep on reading to find out more…
Moroccanoil Overnight Hydrating Leave-In Hair Mask claims to increase your hair’s hydration by 4 x overnight, and your hair will keep the hydration for up to three washes, so it doesn’t like a treatment you use and lose the benefits as soon as you wash your hair.
When applied, the leave-in hair mask makes your hair 3 x easier to detangle the following morning, as well as reducing frizz, minimizing the appearance of split ends, and helps to prevent your hair tangling while you sleep.
Moroccanoil carried out a consumer study in which 98% of the people that participated loved how easy it was to use, 96% of them agreed their hair looked and felt healthy, 94% noticed lasting smoothness and 94% agreed it was comfortable to sleep in.
Although it’s a deeply nourishing leave-in hair mask, it doesn’t leave any greasy residue behind or feel heavy.

- Argan Oil: Rich in vitamin E and antioxidants, this natural oil nourishes.
