Wake up to softer, smoother, more manageable hair. Moroccanoil Overnight Leave-In Hair Mask is a weightless overnight treatment for dry, dehydrated hair, enriched with argan oil, hyaluronic acid and vegan snail mucin. Applied before bed, it works while you sleep to deliver intense hydration, leaving hair feeling softer, smoother and easier to manage by morning, all with no rinsing required. This 120ml size is the full-size bottle for regular use.

What it does for your hair

Dry, dehydrated hair loses moisture overnight and can feel rough and tangly by morning. This leave-in mask helps by delivering a concentrated dose of hydration that works as you sleep: argan oil and hyaluronic acid help replenish and hold moisture, while the vegan snail mucin adds slip and smoothness. The result is hair that feels more hydrated, detangles more easily, has less frizz and looks smoother, and because the formula is weightless and fast-absorbing, it does all that without leaving residue on your hair or your pillow.

How to use it

Apply to damp or dry hair before bed, working from the mid-lengths to the ends. No rinsing needed, simply sleep on it and style as usual in the morning. Use 1 to 2 pumps for fine hair, 2 to 3 for medium hair, and 3 to 4 for thick or curly hair. It can also be used during the day for an instant hydration boost.

Who it's for

This one's for anyone with dry, dehydrated hair who wants an easy, no-rinse way to boost hydration and manageability overnight. We've been perfecting colour, blow-dries and styling for clients in Codsall for years, and an overnight leave-in is one of the simplest ways to wake up with hair that's easier to style.
