Best oil for hair extensions for smooth, nourished lengths

The clue’s in the name: this Healing Oil smooths and protects dry, damaged hair in an instant as the first-and-only hair oil built with a powerful healing protein, giving hair its healthiest shine.

Virtue’s formula is a unique blend of pure, hydrating super oils and the brand’s hair-healing Alpha Keratin 60ku in one bottle. Use this shake-to-activate formula to encourage ingredients like Kalahari melon seed oil and Tahitian tiare flower to start working their magic, infusing each strand with healing proteins for a nourished, healthy glow.

Extensions can start to look a little tired after a while and lose their glossiness. If that’s the case, you’ll want to apply a few drops of JVN Hair Complete Nourishing Shine Drops. A silicone-free, weightless, multi-tasking hair oil that reduces frizz, hydrates and protects from damage while instantly leaving a high-shine finish, these magic drops enhance hair’s shine thanks to hibiscus extract.

This ingredient gives a prismatic effect in the blink of an eye while providing deep nourishment. Bonus: a little goes a long way so you can use this bottle sparingly.

Argan oil is a top choice for nourishing damaged or dry hair and Moroccanoil Treatment Original pulls together everything you need to restore your hair to its best condition. Instantly absorbing, this hair oil eliminates frizz, easily detangles and volumises to give hair a new lease of life.

Moroccanoil works perfectly alongside coloured or over-styled hair as well as extensions, to inject vibrancy and vitality into your strands. The unique absorption properties mean the product is non-oily, blends with other styling products and speeds up drying time.

Crafted for people with dry, damaged hair - whether that’s growing from their head or bonded artificially - this fast-absorbing oil utilises wheat germ to deeply hydrate.

L’Oréal’s Professionnel Serie Expert Absolut Repair 10 in 1 offers a boost of enviable shine and gloss, working to reduce the look of split ends and flyaways and lessening knots and tangles, while its lightweight formulation avoids leaving a heavy, sticky build-up behind.

An ancient Indian hair secret, this cult-favourite HoliRoots Pre-Wash Strengthening Treatment Hair Oil includes strengthening ashwagandha and an active blend of holistic plant roots to nourish your lengths.

Vegan, cruelty-free and formulated without silicones, this gorgeous hair oil smells incredible when applied and comes formulated with castor oil, which thickens, nourishes and hydrates hair all at once. Massage into your scalp and coat your strands, leaving for at least five minutes or ideally overnight to maximise the smoothing, softening and conditioning ingredients.

A must-have in your haircare routine if your extensions are starting to look a little frazzled, the Kérastase Elixir Ultime L’Original Hair Oil works as a primer, finisher or refresher, smoothing the appearance of split ends, while providing heat protection up to 230°C.

Its leave-in formula nourishes and visibly smooths hair for a soft, sleek finish. It also comes infused with a floral-woody scent of violet leaf, freesia, mandarin and musk, ensuring your hair doesn’t just look radiant but smells it too.

Wella Deluxe Rich Oil utilises avocado, coconut and camellia seed oil to ensure a formula that’s just as rich as its name suggests. Infused with a blend of nourishing oils, this budget-friendly elixir offers 10 benefits to your hair: anti-breakage, nourishment, smoothness, UV protection, soft touch, easier brushing, detangling, frizz control, shine and manageability.

Dermatologically tested, it’s one of the best options for those struggling with a sensitive scalp as a result of hair extensions.

Heading off on holiday soon? You’ll want to bring along a bottle of System Professional Solar Sun Oil if you’re hoping to keep your hair looking and feeling good. The rich formula combines UV Filters and a blend of luxurious oils, which protect and deeply condition locks, whilst a generous dose of keratin promotes long-lasting smoothness.

While it’s a thicker oil, it still feels lightweight on the hair, promising not to weigh it down. Designed to restore life to hair that’s been exposed to sun, salt and chlorine, it works wonders on extensions too.

Formulated with a hydrating blend of rich cold-pressed Moroccan argan oil, the Ogx Argan Oil of Morocco Penetrating Hair Oil helps revive locks to leave them nourished and silky smooth.  Ideal for all hair types and textures but especially ticking the boxes for hair extensions, this rich hair oil helps penetrate the hair shaft while renewing and softening hair.

Despite its core focus on argan oil, expect a gorgeous, soft citrus-fresh, floral-green and woody scent when you use this bottle.
