Best overnight hair masks

There’s nothing quite like coating your hair in nourishing creams, dozing off and treating yourself to an #EverythingShower come morning to make you feel like you have your life together.

Overnight hair masks work their magic while you catch forty winks. The fuss-free beauty practice means that while you're getting your REM sleep, your strands are also getting a restorative treatment.

There are formulas designed to tackle every hair concern, from encouraging growth with scalp stimulators and counteracting dehydration with moisture-enriching ingredients, to rejuvenating dry, brittle strands with bond builders. These treatments may just be the secret to healthier hair and they require no time out of your busy schedule.

However, it is important to note that some caution must be heeded.

Younes Khassal, Director at Taylor Taylor London, Liberty Salon explains, “Hair is much more fragile when it is wet, so if you go to sleep with damp or wet hair the friction from moving your head against the pillow can cause more breakage”. For this reason, he suggests intensive formulations that can be applied to dry locks. He adds, “Hair is much more absorbent when it's dry so the ingredients are more effective”.

Another way to protect your mane is to cover it with a shower cap or better yet, a silk scarf, silk hair wrap or opt for a silk pillowcase. Not only will this protect your pillow, but this frizz-fighting material prevents friction by creating a smooth surface, reducing split ends, tangles and breakage in the process.

So, which overnight treatment is best? Khassal advises to “Look out for those that contain natural oils such as jojoba, macadamia, avocado or lavender as well as my golden ingredient - vitamin E, which is a non-negotiable for hair health”. He continues, “Always avoid anything with paragons, sulphates or silicones as they will dry out and weigh down the hair over time”.

Lore Originals Legend

The intensive Lore treatment can be applied to all hair types but, unlike many other formulas on the market, it is designed to slathered onto dry strands. This allows it to penetrate deeper into the hair shaft as the tresses are much more absorbent in this state.

In the cuticle, it gets to work repairing and restoring the strands with amino acids, vegetable proteins, plant oils and omega-rich acids. The deeply conditioning product uses natural ingredients like green tea extract, grapeseed oil and unusually, potato to strengthen from the inside out. It’s entirely vegan and PETA-approved.

Olaplex No.8 Bond Intense Moisture Mask

Best for: Bond-building technology

All of the ever-growing Olaplex range puts the brand’s proprietary complex at its heart as it has the scientifically proven ability to repair the hair cuticle. This is step eight in the routine and is designed to follow the shampoo.

The light texture is quickly absorbing and should be applied onto the mid and ends (not the roots) for 10 minutes before washing out. The bond-repairing product boosts shine, moisture and body, while also smoothing in spades. No matter your concerns - be it thermal damage, frizz, or the desire to define curls - this product has visible results.

Perhaps the only downside is that it needs to be kept on for 10 minutes - a fair amount of time to be waiting in the shower, so perhaps best saved for a bath. Alternatively, since you can’t overuse Olaplex products, apply before you doze to work its magic overnight.
