It took me a long time to figure out hair oil (not to be confused with scalp oil). My hair is fine, colored, and damaged. All it took was a few overzealous pumps on wet hair, and the greasy finish would make it seem like I hadn’t bothered washing my hair at all. I know now that all that product wasn’t necessary: If you’re using good hair oil, a pump or two will do the trick.
But how do you spot good hair oil? Beyond an ingredients list stacked with moisturizing oils, there’s also consistency to consider — do you want something thick to quench your ends before blow drying, or something thin to smooth down flyaways before washday? Either way, I tried dozens and spoke to experts to find a list of eight options; each oil featured has different strengths, but each one is a solid, expert-recommended option for hair in need of either a little TLC or a helping, smoothing hand in these windier months. If you’re new to hair oiling, my recommendation is to start out with one of the more affordable options: Our experts love them, and they very well may do the trick. I’ve also included some more heavy-duty options at a higher price point that I’ve personally tested on my dry, split-prone hair and loved.
Update on February 5, 2025: Updated prices and checked stock for all products.
What we’re looking for
Ingredients
Most hair oils are made up of other oils, from argan and moringa to jojoba and sunflower oils. Argan oil is a popular hair-oil ingredient: It’s been used for centuries to smooth and soften hair, and you’ll find it in the ingredients list of several options here. It’s also a smaller molecule, which is another thing I’m looking for: Heavier oils such as coconut can weigh the hair down and make it appear greasy.
Elsewhere, I’ve also looked for hair-strengthening ingredients: Vitamins like biotin and tocopherol can improve the strength of hair over time.
Price per ounce
I will say upfront that hair oil is not at all cheap — some of these options even go as high as $30 per ounce. What’s worth noting, though, is that you only need to use them very, very sparingly. In most cases, one pump or a pea-size amount is enough. So while the upfront cost may seem a little steep compared to, say, a shampoo, your hair oil is going to last you a whole lot longer. For clarity, I’ve listed prices per ounce.
Best hair oil overall
Ingredients: Moringa oil, argan oil, bamboo extract | $10 per oz.
Strategist senior editor Jen Trolio told me about Verb’s Ghost Oil. (I was already familiar with the line, and crowned its conditioner as my favorite of all time but hadn’t got my hands on its oil.) It contains common hair-oil favorites such as moringa and argan oil and the less-common bamboo extract. As bamboo is rich in silica, an ingredient known for its hair-strengthening properties, it’s a great addition. I was drawn to a few things in Trolio’s recommendation. First, it can be applied to wet or dry hair: This means it can be used to add moisture to freshly washed hair and also seal in and prolong that moisture in second- and third-day hair. Crucially, Trolio told me the product doesn’t build up when used on consecutive days, which is key to avoid that greasy look and feel you can get if you overdo it with a hair oil. “It’ll feel slick on your fingers, has a good slip to it, but it doesn’t make the hair greasy or oily looking, just does a great job of smoothing,” says Trolio. She uses the oil on both her and her daughters; they all have fine hair so can be sparing with the application. Those with thicker hair need only add a pump or two extra to get those same results. Since it’s suitable for all hair types (and not too heavy for fine hair), imperceptible, both sealing and moisturizing, and a very reasonable price, I’m naming it my top pick overall.
Best less-expensive hair oil
Ingredients: Argan oil | $2.60 per oz.
I was thrilled to hear one of my experts — stylist and salon owner Rogerio Cavalcante — recommend argan oil. In Morocco its benefits for the hair have been known for centuries, and since my trip to Marrakech as a teenager, I’ve always kept a bottle on my nightstand. You’ll find it in the ingredients list of several other oils on this list (it’s a hair-oil backbone), but it also works pretty well as a main ingredient. It’s packed full of moisturizing oleic acid and linoleic acid, it’s been proven to protect against free-radical damage plus improve elasticity, and anyone who’s swiped some on their ends will know it smooths even the most split of ends. Argan oil is a smaller molecule than other oils (such as coconut), meaning it can penetrate the hair easily; that’s what makes it so effective. Cavalcante recommends this specific oil from Hask for its rich consistency that “distributes really easily throughout the hair, making it both soft and shiny.” He also says that the ingredients argan and grape-seed oils make it “ideal for thicker hair types and dry ends as it instantly adds nourishment and reduces frizz.” If your hair is super thin like mine, though, a standard drugstore bottle of argan oil will also do the trick.
Best hair oil for curly hair
Ingredients: Almond, sunflower, castor, and jojoba-seed oils | $13 per oz.
To give some smoothing shine to curls without weighing them down, lightweight oils such as jojoba and almond are the way to go. This Freewill oil has both as well as stimulating castor and sunflower oil (both moisturizing hair oils with some evidence to suggest they promote hair growth). Stylist Gregory Patterson is so fond of the oil as it “fortifies the delicate curls and edge hairs that are weaker and more prone to breakage and dehydration,” all while remaining lightweight. “I love it because it’s nourishing and targets a specific hair zone for a more tailored care solution for your hair at those delicate edges.”
Best hair oil for breakage
Ingredients: Moringa and bixa-orellana-seed oils, tocopherol (vitamin E) | $18.50 per oz.
Like the Verb Ghost Oil, this R+Co oil has ingredients to both moisturize and protect. Moringa and bixa-orellana oils moisturize, while tocopherol (which is a type of vitamin E) protects against free-radical damage. The result is smooth, shiny, and eventually healthy hair. It’s the go-to oil of Strategist junior writer Brenley Goertzen, who experienced extreme breakage as her hair began falling out during college. “I use it as a finishing oil to tame down breakage on freshly clean and dry hair,” she says (I will just add that you can use the oil on wet hair, too). “I put one-to-two pumps in my hands and then use it just on the top layer of my bangs and hair to smooth and add shine — I’m not a natural blonde so I do get damage sometimes from highlighting my roots” adds Goertzen.
Best for really damaged hair
Ingredients: ‘K18 peptide,’ avocado, sunflower oil, squalene | $79.41 per ounce
This is eye-wateringly expensive. Ridiculously expensive, even. But for truly damaged, frizzy, split hair, it’s worth it. If you’re new to hair oiling, you don’t need to jump straight to K18. But if nothing else is working, in my experience, this will.
As our beauty columnist Rio Viera-Newton puts it, “K18 works by delivering a patented amino-acid chain to the inner structure of your hair, replacing missing amino acids and regenerating the bond to repair your hair.” This oil contains that amino-acid chain (what the brand refers to as K18PEPTIDE) as well as some other oils, but is entirely silicone free. That makes it a rarity — quite heavy-duty and restorative, but also entirely lightweight. I’ve noticed a real difference with respect to shine and smoothness since I added it into my routine in November (it’s also the product that I missed most sorely when I visited my parents over the holiday). As with all K18 products, you don’t need much of it, and I’ve managed to make a little vial of it last for almost three months. I’m not planning on repurchasing, but that’s just because thanks to an effective routine, my hair is no longer splitting or frizzy or altogether in dire straits. If it ever gets back to that point, though, I’ll order another bottle straight away. Because it works. (If you pair it with the mask, it’s even better, and K18 has a mini essentials set that’s a good, slightly more affordable introduction for a newbie.)
Best for smoothing
Ingredients: Annatto, argan, and pumpkin-seed oils | $14.16 per oz.
It took two recommendations for our beauty columnist Rio Viera-Newton to invest in this hair oil, but at roughly $14 per ounce, it actually sits in the cheaper to mid-range of the hair oil shelf. For the price, you get an ingredients list containing argan (my favorite), pumpkin-seed, and annatto oils. There’s been a lot of clinical studies to suggest that pumpkin-seed oil can stimulate hair growth, and it’s known to be kind to the scalp. Annatto oil is popular particularly in K-beauty products: It can moisturize, soften, add shine, and even improve the vibrancy of hair colors. Overall, both Viera-Newton and I argue that makes it worth the slightly steep initial investment above the $60 mark. “This is the best hair oil I’ve ever tried in my life. The texture is thick, which makes it really easy to work it into your hair evenly. And it works like an actual dream,” she says.
Best for dehydrated hair
Ingredients: Jojoba, coconut, sunflower and sesame oil | $18.75 per oz
This is heavy-duty stuff. It’s actually a pre-shampoo treatment; you apply it anywhere from ten minutes before to the night before you shampoo. And I understand why: On fine hair like mine, it shows up very visibly as oil and therefore needs to be washed off before styling (but it does wash away easily; I’ve never noticed any residue after a shower). But all that grease pays off: I always notice that my hair holds onto far more moisture post-wash when I use this oil. I’ve been on a pretty intensive, SOS hair regime the last few months, so I will sleep in a layer of this, wash my hair, then apply K18 hair oil. And like with the K18 oil, I’ll echo the same advice: You don’t need to jump straight to this oil, but if your hair is truly dehydrated and nothing seems to be doing the trick, it could give you the hydration boost you need. It also smells divine, like jasmine and magnolias, which I love.
I do have a gripe, though: Below room temperature, the oil congeals, and you have to run it under hot water to liquefy it again. That’s annoying, but at least it’s not an everyday oil — so you just have to remember to do that on washdays.
Best hair and scalp oil
Ingredients: Biotin, rosemary oil, peppermint oil | $5 per oz.
This is one of those bottles you find in your mom’s cupboard that truly does the trick. The ingredients list is simple — essential oils like rosemary and peppermint, plus biotin, a hair-care staple — which makes it effective and suitable for all hair types, says Patterson. It’s also an all-rounder: It can be used as a hair oil for split ends, a leave-in treatment, a pre-shampoo treatment, and a detangler. The mixture of nourishing oils is also kind to scalps, and oils like peppermint are believed to boost blood circulation in that area, which stimulates healthy hair growth.
