Few things give you the same instant confidence boost as a trip to the hairdresser’s. Even if it’s just a trim or a blow-dry, there’s something about that final flourish – when they rub a silky, gorgeously scented oil between their palms and glide it through your hair – that makes you feel like you’re stepping out of a magazine shoot.
But we all know London salon prices can make your bank account cry, especially if you’re a regular. The good news: you don’t actually need to fork out half your pay check for that just-left-the-salon shine. Your humble but mighty hair oil can help you achieve the same glow from the comfort of your own home.
And it’s not just about the looks: hair oils can hydrate and visibly strengthen your strands, particularly if you have damaged hair or splits. We’ve tested some of the newest and most popular ones from cult brands so you can skip the greasy mishaps and head straight to your dinner plans with flawless hair. Scroll down to see our findings.
What exactly is a hair oil and what can you use it for?
A hair oil is more than just a glossy finishing touch. Traditionally, oils were used in beauty rituals for centuries – argan in Morocco, coconut in South Asia, jojoba in Native American traditions – long before the modern blow-dry bar made them a salon essential.
What today’s formulas do is take that ancient idea of nourishment and repackage it in a way that fits into a five-minute routine, sitting somewhere between styling product and treatment.
A good oil has to be rich enough to smooth, hydrate, and seal the hair cuticle, but light enough to disappear once it’s in. Too heavy, and you’re back in the shower with limp, greasy roots; too light, and you’re wondering why you spent £30 for something that smells nice but does nothing.
That’s why you shouldn’t choose a hair oil based on branding alone. You want slip without slick, shine without weight, protection without residue. The right oil should behave almost invisibly, making your hair look like it just is that glossy, rather than looking like you’ve poured something on top of it.
How to buy the right hair oil for your hair
Not every oil will work for every kind of hair. Here’s what’s worth checking before you commit:
- Weight of the formula: Fine or thin hair does best with light, fast-absorbing oils (like argan, grapeseed or blends with silicones for slip). Thicker, coarser or curly hair can handle richer oils formulated with coconut, castor, shea-based blends. These actually sink in and soften.
- Finish: Some oils are high-shine for that polished, glossy look, while others are more matte or “invisible,” just to smooth frizz. Decide whether you want a mirror finish or a subtle, natural sheen.
- Multi-tasking vs. specialist: Do you want an all-rounder (heat protectant, frizz control, hydration in one) or a targeted treatment, like strengthening split ends or adding UV protection?
- Ingredients that matter: Look for nourishing natural oils (argan, jojoba, avocado) paired with lightweight silicones if you want styling benefits. Avoid anything overloaded with heavy mineral oil unless you’re treating very coarse hair types.
- Absorption: The best oils disappear after a few seconds of smoothing through – no residue on your hands or greasy roots. If it lingers, it’ll weigh you down.
- Packaging and pump: Sounds minor, but dosing matters. A good pump (or dropper) gives you control – one or two drops too many is the difference between glossy and greasy.
The 8 best hair oils for smooth, glossy hair
1. Gisou Honey Infused Hair Oil
20ml, £19.00, available at Cult Beauty
The Gisou Honey Infused Hair Oil has been on my radar for ages – it’s one of those cult products everyone seems to rave about. And I totally get why. From the first use, it feels indulgent but never heavy. The texture is silky and smooth, almost like a serum, and it disappears into the hair without leaving residue.
The hydration payoff is real. My ends, which normally look a bit frazzled after heat styling, instantly looked healthier and glossier. What surprised me most was how long it lasts – even the next day, my hair still felt soft and frizz-free, without me needing to reapply. It doubles beautifully as both a styling product and a treatment: I’ll run a few drops through damp hair before blow-drying for shine and protection, or use a richer amount overnight as a deep treatment.
The scent is half the magic. It’s delicately sweet, like warm honey, with a deliciousness that makes you want to breathe it in again and again. Not cloying, just subtle and addictive.
If you’re looking for a multi-tasking oil that hydrates, protects, and makes your hair look instantly polished, this one truly lives up to the hype.
2. Moroccanoil Treatment Original 100ml
£38.50, shop at LOOKFANTASTIC
The Moroccanoil Treatment Original is one of those products that truly deserves its cult status. From the first use, it makes styling easier and hair instantly sleeker – almost like I’ve pressed fast-forward to the “after” shot in a salon ad.
The texture is rich and silky, but it never feels sticky or heavy. I like to use it on towel-dried hair before blow-drying, and it noticeably cuts down drying time while making detangling effortless. My brush just glides through. On dry hair, it works just as well as a finishing oil -smoothing down flyaways, adding gloss, and giving ends that healthy, sealed look.
The argan oil and vitamin blend really do the heavy lifting here. With regular use, my hair has felt softer and looked shinier, but it also seems stronger and less prone to those little split-end snaps. And the scent is gorgeous – warm, slightly spicy, and very “salon,” but without being overpowering. If you want an oil that does it all – conditioning, frizz-taming, shine-boosting, and even speeding up your blow-dry – this one is a classic for a reason.
3. ARKIVE The Good Habit Hybrid Oil
50ml, £15.00, available at LOOKFANTASTIC
The ARKIVE Headcare Good Habit Hybrid Oil is your go-to everyday hair oil. The texture is light and silky, so it smooths through the hair effortlessly without leaving behind any greasy residue. Just a pump or two is enough to tame frizz, add moisture, and give hair a natural, healthy-looking shine.
The blend of baobab and jojoba oils works beautifully to nourish both the hair and scalp. My ends felt softer right away, yet my roots stayed light – it strikes that perfect balance of hydration without heaviness, which makes it ideal for everyday use.
The fragrance is another highlight. ARKIVE’s Future Bloom scent is uplifting and modern, with bright mandarin and rhubarb softened by vanilla and white florals. It lingers gently, giving your hair that just-washed freshness throughout the day.
Overall, this is a clever hybrid: nourishing enough to act like a treatment but light enough to use as a daily finishing oil. If you’re after shine, smoothness, and a beautiful scent in one step, this ticks all the boxes.
4. Aveda Miraculous Oil High Shine Hair Concentrate 50ml
£34.00, available at Cult Beauty
I’ve tried a lot of hair oils over the years, and most of them either sit on top of my hair making it look greasy or disappear without doing much at all. Aveda’s Miraculous Oil feels different from the very first drop. The texture is silky and lightweight, so when you rub it between your palms it feels almost like liquid satin. As soon as I worked it through my mid-lengths and ends, my hair looked smoother, shinier, and somehow “finished” — like I’d just stepped out of a salon blow-dry.
What I love most is how balanced it feels: rich enough to tame frizz and flyaways, but light enough that it doesn’t weigh my hair down. For context, I have fine hair that can get oily fast, and this still left me with that glossy, reflective shine without residue. The scent is another bonus – a calming, spa-like blend of botanicals that turns a quick styling step into a mini ritual.
I’ve used it both before blow-drying for heat protection and as a finishing touch on dry hair, and in both cases it made a visible difference. Think sleeker ponytails, softer ends, and that subtle “who just did your hair?” kind of shine. It also keeps frizz under control for hours, even on humid days, which is a big win.
In short: if you’re after an oil that feels luxurious but actually works, this one nails it. It gives you the glossy finish without the heavy, greasy trade-off and a little really does go a long way.
5. Aussie Mega Smooth Hair Oil
£9.99, available in Amazon
Sometimes you just need a simple product that does the job, and Aussie’s Mega Smooth Hair Oil is exactly that. It’s lightweight, budget-friendly, and makes an instant difference when your hair needs a little extra care.
The texture is silky but not greasy, and just a couple of pumps are enough to tame frizz, boost shine, and soften your hair straight away. It’s also great for everyday protection, whether from heat styling, brushing, or just battling unpredictable weather.
The blend of macadamia, safflower, and coconut oils works really well together – nourishing and smoothing without ever feeling heavy. The result is hair that looks healthier, shinier, and easier to manage.
It may not be a luxury treatment, but as an everyday staple for keeping your hair soft, smooth, and frizz-free, it delivers exactly what you need, with the fun, unfussy vibe Aussie is known for.
6. Curlsmith Bonding Oil 60ml
£25.00, shop at Curlsmith
I’ll be honest – I’ve always been a little nervous about using oils on my curls. They usually either sit on top of my hair like grease or leave behind a film that builds up over time. Curlsmith’s Bonding Oil completely changed my mind. It’s weightless, almost like a serum, and disappears the second I smooth it through my hair. No heaviness or residue – just soft, silky curls that look instantly healthier.
What stood out for me is how quickly it seals down frizz and rough cuticles. I can scrunch a few drops into damp hair before diffusing, and it gives me that glossy, defined finish without flattening my curls. On dry hair, it’s perfect for reviving ends that are starting to split or look a little tired. My curls feel smoother, stronger, and so much shinier – I actually had someone ask if I’d had a fresh cut after using it.
If you’ve avoided oils in the past because of build-up or heaviness, this one really is different. It gives you all the nourishing, strengthening benefits without weighing your hair down. Think of it as a repair treatment and finishing touch rolled into one.
7. Goldwell Stylesign Weightless Shine Oil 100ml
£17.00, available at LOOKFANTASTIC
This is one of those products that instantly makes styling easier. Unlike most oils, it comes in a spray format, which makes application quick, even, and mess-free – no more accidentally over-pouring and ending up with greasy roots.
True to its name, it really is weightless. A few spritzes leave hair sleek, smooth, and noticeably shinier without flattening volume or texture. I love that it works just as well on my naturally wavy hair as it does when I straighten it – the finish is glossy, not greasy, and it helps colour look brighter and more luminous.
The frizz resistance is impressive too. I tested it on a humid day, and my hair stayed smooth and polished far longer than it usually does. It’s also versatile: spray it on towel-dried hair before styling for softness and moisture, or mist it lightly on dry hair as a finishing touch for that just-left-the-salon shine.
If you want a fuss-free oil that delivers high-shine results without any heaviness, this one is a great everyday option, especially if you’re prone to frizz.
8. Oribe Gold Lust Nourishing Hair Oil 100 ML
£54.00, available at SpaceNK
The Oribe Gold Lust Nourishing Hair Oil feels like pure luxury in a bottle. From the first pump, you can tell it’s a cut above. The texture is featherlight yet rich, and it sinks into the hair almost instantly without leaving any residue.
I’ve used it on both damp and dry hair, and it delivers every time. On damp hair before blow-drying, it adds a layer of protection while leaving my strands sleek and shiny. On dry hair, it smooths frizz and gives that polished, salon-finish gloss. What I appreciate most is that it never feels heavy – just healthy, nourished, and soft.
The formula is packed with argan oil plus notes of bergamot and cassis, which makes it smell as good as it looks. Over time, I’ve noticed my hair feels stronger and less prone to breakage, especially at the ends where I usually see damage first. The added UV and heat protection is a big bonus, making it a true multi-tasker for colour-treated or stressed-out hair.
It’s definitely a splurge, but if you’re looking for a hair oil that treats and protects while making your hair look instantly glossy, this one earns its place on the top shelf.
