If you've ever given your hair a little extra TLC, you've probably tried some variation of a hair mask, whether a DIY version or one off the drugstore shelf. Nothing against those hair masks—they work, for certain—but just like a traditional face mask, they're only left on for 10-20 minutes before they're removed. That's usually enough time to tackle a wide range of hair concerns, but if you really want to up the ante, reach for an overnight hair mask.
Think of an overnight hair mask as your routine hair mask, but slightly upgraded to give your hair what it really needs as you snooze. These formulas are meant to be worn for hours on end, all the while delivering the nutrients your hair needs to combat damage, excess frizz, dryness, split ends, and more. That's right, with the best overnight hair masks you are one eight-hour sleep away from a healthier, stronger, and shinier mane.

This pick earns the top spot on our list because it truly works for any hair type. Just one night of this overnight mask leaves you with shinier, silkier, and more manageable hair, all thanks to its impressive blend of amino acids, time-release conditioners, and Living Proof’s very own Healthy Hair Molecule-infused formula. It keeps a lust-worthy sheen on your hair for days (a full week or after five shampoos, in fact), and it’s safe enough for even color-treated strands to enjoy. Just apply to your hair (damp or dry) before bed, catch some Zzz’s, and wash (or don’t wash, it’s up to you) for fabulous hair. Seriously, it’s that easy.
Have extremely brittle and dry locks? Get acquainted with this quenching and fortifying mask. The formula is enriched with superfood extracts, silk amino acids, and leaves out harmful ingredients like mineral oils, petrolatum, parabens, and sulfates to give your hair the TLC it deserves. The results? Quenched, nourished hair with way less breakage.
Split ends are never fun to deal with and seem much harder to repair than other hairy situations (pun intended). But, when there’s a will, there’s a way, and this mask is the way to seal the deal on split ends. It includes hair heavy-hitters like argan oil, coconut oil, and shea butter to tame frizz, repair split ends and condition from root to tip to bring back a “virgin”-like feel to your mane.
Whether you dyed your hair a little too much or went haywire with your heated tools, this hair mask is here to provide some support.

You also won’t find additives like parabens, phthalates, mineral oils, and formaldehyde in this hair mask, so your hair will look and feel better by morning.
If frizz has gotten you down, then this nourishing hair mask will do just the trick. It includes smoothening and hydrating properties like shea butter and shea oil, wheat microproteins, and phospholipids to strengthen, hydrate, and soften strands for a sleeker and frizz-free look. Plus, you don’t have to rinse this mask out in the morning—just slather it on, go to bed, and wake up without any morning frizz.
If you have greasy strands by morning time without fail, then chances are you need some oil control. Enter this overnight mask. What makes this one so great for oily strands is that it contains tea tree oil, a known skincare favorite for oil control. Monoi, pequi, and jojoba oils are also introduced to the mix to give your hair the nourishment and conditioning it needs to stay soft (but never greasy) by the A.M.
If you have color-treated hair, then you have to be a little pickier about what you put on it, which is why we’re recommending this dry hair mask for all of you colorphiles. It’s not only gentle enough for color-treated strands, but it also works to repair and soften hair overnight in a lightweight, airy spray formula. This formula includes a vegan silk extract that makes your hair shinier by morning time and assists in softening and detangling hair, so you can say goodbye to intense knots and dry post-color texture.
Since thin hair is very prone to looking greasy and weighed down, it requires a more lightweight formula. Enter this all-natural pick, which has a low ingredient list that will nourish hair without leaving excess residue behind. Key ingredients include coconut oil, castor oil, and rose extract to give thin hair moisture, strength, and nourishment without a greasy or oily feeling after washing it out.
Thick hair is all about the heavy hydration, and this overnight mask will provide exactly that. This rich treatment is perfect for thick hair because of its dimethicone-infused formula, which is a great ingredient for creating a straighter, silkier look. This strengthening formula also works to prevent breakage and make hair look healthier, sleeker, and softer.
Every curly-haired person knows the struggle of dehydrated, frizzy locks. So, if that sounds like your hair, then grab this ultra-hydrating hair mask.

It’s safe enough for color-treated hair, keratin-treated hair, and extensions.
