How to Use Our Overnight Leave-in Mask: Everything You Need to Know
An overnight leave-in mask is one of the easiest ways to upgrade your hair routine, because it works while you sleep. You put it on before bed, and you wake up to softer, more hydrated, easier-to-manage hair. No extra step in your morning, no time at the sink. Here's exactly how to use it, how much to reach for, and how often, so you get the most out of every night.
The short version: apply Overnight Leave-in Mask to damp or dry hair before bed, from mid-length to ends, and leave it in. There's no rinsing. In the morning, you just style as usual.
What is an overnight leave-in mask?
Think of it as skincare logic for your hair. Instead of a rinse-out treatment that gets a few minutes in the shower, an overnight mask is a leave-in, so it has all night to condition and hydrate. It's designed to stay in your hair while you sleep, then leave you with soft, hydrated, manageable hair by morning.
Ours is made for all hair types, and it's built around argan oil, supercharged hyaluronic acid, and vegan snail mucin, ingredients that help nourish, hydrate, and condition overnight.
Do you apply it to damp or dry hair?
Either works. You can apply Overnight Leave-in Mask to damp or dry hair before bedtime, whichever suits your routine. If you've just washed, work it through towel-dried hair before bed. If it's a non-wash night, dry hair is completely fine.
How much should you use?
This is where hair type comes in, and it's the one thing worth getting right. Use enough to coat your mid-lengths and ends without overloading finer hair:
- Fine hair: 1 to 2 pumps
- Medium hair: 2 to 3 pumps
- Thick or curly hair: 3 to 4 pumps
If you're not sure, start with less. You can always add a little more, and finer hair especially does better with a lighter hand.
Where do you apply it?
From mid-length to ends. That's where hair tends to be driest and most prone to tangles and split ends, and it keeps the product where it does the most good. There's no need to work it into your roots.
Do you rinse it out?
No. This is a leave-in mask, so it stays in overnight with no rinsing necessary. You just style as usual in the morning.
What about the morning after?
Style as you normally would. Because the mask helps condition and smooth overnight, hair is easier to manage and detangle when you wake up, which can make your morning routine simpler. Nothing extra required, just carry on with your usual styling.
How often should you use it?
You can use it as often as your hair likes. For very dry or dehydrated hair, a few nights a week is a good place to start; for hair that only needs an occasional boost, once a week may be plenty. Let how your hair feels guide you, and adjust up or down from there.
Can you actually sleep in it?
Yes, that's the whole idea. The mask is designed to be worn overnight and to work while you sleep. Apply before bed, let it do its thing, and style in the morning.
Bonus: it's not just for nighttime
Overnight Leave-in Mask can also be used as a daytime treatment, especially on second-day or third-day hair, for an instant boost of hydration. A small amount through mid-lengths and ends can refresh hair between washes.
