Who can say no to waking up with hair that feels utterly fabulous?

Sleep is one of our favourite things on earth, and not just because it stops us from feeling tired (though that’s a great benefit). But whether or not you’re lucky enough to experience exciting things like lucid dreaming when you rest, it’s always a great time to allow your favourite beauty products to really get to work. Aside from the night serums you might apply as part of your evening skincare routine, another thing you can put on before bed to make you feel gorgeous in the morning is an overnight mask or treatment for your hair.

Fortunately, there are lots of treatments to choose from that can benefit your hair by being left on for longer. And as well as dealing with dryness, dehydration and even damage, they can help with lack of shine and flat roots to help you wake up to healthier and stronger hair that’s also bouncier, glossier and more manageable.

How to use a hair mask or treatment overnight

Can you leave a hair mask in overnight? Of course. Just don’t forget to shampoo yours out twice the following morning if you’re prone to greasy hair (and to wear a shower cap to protect your bedding). There are leave-in options too, meaning that there’s no need to rinse (perfect if you’re a little time-short!). Instructions as to how often you should apply your hair mask will vary from product to product, but usually once a week suffices.


Now that you’ve realised that an overnight hair mask is actually a wonderful idea for all sorts of reasons, one thing remains: which one to get! From those for dry hair to those specifically for your hair AND scalp, here’s a selection of our favourite hair masks and treatments for all hair types and concerns. Frankly, they’ll leave your hair looking and feeling as fantastic as a celebrity’s.

If you don’t find anything to suit you here, we have even more great overnight hair treatments available to buy here.

Best overnight hair treatment for bouncy hair

Try: Philip Kingsley Elasticizer Extreme Rich Deep-Conditioning Treatment (£19.50)

• Size: 75ml

There’s something about having beautifully bouncy hair that just screams health and happiness. So, how do you get beautifully bouncy hair without necessarily having to spend a few hours in a salon chair? This treatment moisturises hair without weighing it down while reducing the likelihood of breakage, ultimately leaving you with locks that are shiny, silky and – of course – bouncy. It’s ideal for curly hair types that are feeling dry and damaged. Another great thing about it? An overnight application isn’t your only option. You might prefer to wear it at the gym and wash it out post-exercise or, as a styling cream.

Best overnight hair treatment for strengthening hair

Try: Fable & Mane HoliRoots Hair Oil (£29)

• Size: 55ml

• Silicone-free

• Vegan

Infused with notes of jasmine sambac and red champaca flowers, one sniff of this treatment is a joy in itself, but the benefits it has for your hair are even better. Its strengthening ingredient of ashwagandha will leave you with locks that look considerably healthier and shiner from root to tip, for a start!

Best overnight hair treatment for the scalp

Try: The Inkey List Caffeine Stimulating Scalp Treatment (£14.99)

• Size: 50ml

It’s easy to forget the importance of your scalp when it comes to haircare. You may be missing a trick to ignore it, though, because a healthy scalp = healthy hair and it therefore should be treated with the utmost care and attention.

Best overnight hair treatment for bleached hair

Try: Revolution Haircare Plex 3 Bond Restore Treatment (£10)

• Size: 100ml

• Vegan

Bleached hair looks fabulous, but it can also cause a lot of damage. Because of this, investing in a suitable treatment to restore the bonds of your hair is a very wise idea! This one in particular has a lot going for it: a protein system made from three different types of plant protein to target different parts of the hair fibre; a combination of phytantriol and provitamin B5 to keep hair hydrated and in good health; and a mix of conditioning agents to smooth everything over. Blondes have more fun indeed.

Best overnight hair treatment for split ends

Try: Philip Kingsley Bond Builder Restructuring Treatment (£28)

• Size: 150ml

• Vegan

Although picking at your split ends can be a bit of a guilty pleasure, it’s really not the best thing for your hair health overall. Instead, we recommend using a treatment which works beneath the surface of the hair to repair and prevent breakage. Regular use should leave you with stronger hair that’s satisfyingly smooth to the touch.

Best overnight hair mask for frizz

Try: Bumble and Bumble Hairdresser's Invisible Oil Mask (£32)

• Size: 200ml

Boosted with a moisturising blend of moringa oil and pomegranate seed extract and infused with the brand’s signature blend of six lightweight oils, this hair mask for dry hair offers nourishment and a reduction of frizz for all hair textures.

Best overnight hair treatment for damaged hair

Try: The Hair Lab by Mark Hill Bond Repair Bond Building Treatment (£19.99)

• Size: 150ml

• Sulphate-free

• Vegan

If your hair’s damaged or brittle for whatever reason, it’s time to take action. This super concentrated treatment reduces breakage and leaves hair literally stronger and healthier. A strong contender for the best hair treatment for damaged hair.

Best overnight hair treatment for coarse, dry hair

Try: Lee Stafford Argan Oil from Morocco Deep Nourishing Treatment (£12.99)

• Size: 200ml

• Vegan

Formulated with argan oil from Morocco, this overnight hair treatment will give you the intense boost of moisture you need to fall back in love with your locks. And it smells divine!

Best overnight hair mask for shiny hair

Try: Grow Gorgeous Balance Hair and Scalp Mask (£25)

• Size: 200ml

• Vegan

So, you want incredibly soft and shiny hair – look no further! We adore this hair and scalp mask for the wealth of superior skincare (for the good of your scalp, naturally) and haircare ingredients: an oat lipids complex to protect the scalp’s natural barrier and lock in moisture; hyaluronic acid to smooth hair and guarantee silkiness; tung wood and rapeseed oil to fight frizz and heat damage; pataua, acai and sweet almond oils to nourish every single strand; and blended green tea extract and fruit acid to smooth hair cuticles and reveal a glorious shine.

Best overnight hair treatment for dry hair

Try: Bumble and Bumble Hairdresser's Invisible Oil Hot Oil treatment (£24)

• 4 pack

Putting this hot (or warm, rather) oil treatment on your hair doesn’t just feel luxurious, it also nourishes and smooths your locks making them quite the opposite of dry. A must if you and your mane are in need of some urgent TLC.

Best overnight hair treatment for hair growth

Try: Umberto Giannini Grow Mask Hair and Scalp Treatment (£9.25)

• Size: 230ml

• Vegan

This treatment could be worth adding to your routine if you’re looking to reach new lengths. It contains caffeine and black coffee seed extract to stimulate circulation at the scalp, as well as organic pea sprout extract and marine nutrients to promote overall hair health.

Best overnight hair mask for thinning hair

Try: Bondi Boost Miracle Mask (£25.95)

• Size: 250ml

• Vegan

If you’re suffering from thinning hair, it can sometimes feel like the only thing to help matters would be a miracle – like this one, which contains procapil to fight the follicle ageing process and prevent hair loss, Redensyl to promote healthy hair growth and argan oil to nourish.

Best overnight hair mask for curly hair

Try: Umberto Giannini Curl Jelly Intensive Mask (£9.25)

• Size: 200ml

• Vegan

A wonder product for anyone blessed with curls, this intensive mask banishes frizz and leaves your hair enviably shiny and bouncy.

Best sleep accessories for when you’re not wearing an overnight hair treatment

You only really need to apply an overnight hair mask or treatment about twice a week, but there are other ways to protect and care for your hair while you sleep.

Try: Kitsch Satin Pillowcase Blush (£15)

The silky surface of this satin pillowcase doesn’t just stop frizz from forming, it’s also considerably smoother on your face than your standard pillowcase material. It won’t soak up as much moisture either, which means more of that good stuff for your skin.

Try: Kitsch Satin Sleep Scrunchies - Blush (£6.50)

• Pack of 5

These satin scrunchies won’t pull at your hair or crimp it while you sleep, meaning less breakage and frizz. And, actually, they’re so pretty that you’ll want to wear them during the day too.
