What Does Overnight Leave-in Mask Do?

Most intensive hair masks need to be rinsed out, limiting how long the active ingredients can actually work on your hair. This mask flips that: applied before bed, it's left on all night, giving Argan Oil, Hyaluronic Acid and Vegan Snail Mucin hours to hydrate and condition rather than minutes.

Seven molecular weights of hyaluronic acid work at different depths to hydrate and boost elasticity, while vegan snail mucin conditions and helps lock in that moisture through the night. By morning, hair feels noticeably softer, smoother and easier to detangle.

Who Is It For?

Ideal for:

• Dry or dehydrated hair
• Hair that tangles easily
• Frizz-prone hair
• Hair with visible split ends
• Anyone who wants an intensive treatment without a rinse-out step
• Second or third-day hair needing a quick hydration boost

Do I Need to Rinse This Out in the Morning?

No — that's the point of an overnight leave-in mask. Apply it before bed and simply style as normal in the morning; there's no rinsing step, and MOROCCANOIL confirms it won't leave residue on your hair or pillow.

How Many Pumps Should I Use?

It depends on your hair thickness: 1-2 pumps for fine hair, 2-3 pumps for medium hair, and 3-4 pumps for thick or curly hair, applied from mid-lengths to ends on damp or dry hair.
