Hair oil can be a bit intimidating. While we want our hair to look like it’s glistening, we certainly don’t want it to look (or feel) downright oily. While all hair types can benefit from using oil, the catch is finding one that works best for your strands in particular. For thicker hair types and some curlies, rich oils like cold-pressed castor or coconut oil can be used as a luxurious overnight nourishing treatment. Got fine hair with flyaways? Your locks might enjoy an ultra-light, almost invisible oil (yes, those exist) that won't weigh it down after styling, yet will add to its luster and keep errant strands in place.
And if you've been getting just a little too happy with curling irons and DIY hair-coloring kits (it happens to the best of us!), you might be left with too many broken strands to count. Going back to basics with a simple hair oil mask can bring your tresses back to life and repair damaged ends.
Below, we rounded up the best hair oils that’ll transform your locks.
Best Overall: Ouai Hair Oil
Contains nourishing oils
Created by celebrity hairstylist extraordinaire Jen Atkin, this lightweight oil can be applied to wet or dry hair. The formula—which contains a mix of African galanga, ama oil, and Asian borage oils—works to completely eliminate frizz and tame unruly hair while also preventing your color from fading and protecting against heat damage. It also doubles as a subtle hair perfume with notes of gardenia, violet, ylang-ylang, and white musk. Use one or two pumps and apply from midshaft to ends to smooth down any wayward strands and leave behind a gorgeous glossy sheen.

No matter when or how you use it, just know that the formula—rich in argan and camellia oils—is smoothing your strands and enhancing your shine. The best part of all? For how deeply nourishing it is, it's incredibly lightweight, so you can trust it'll bring life back to your hair rather than weigh it down or leave it greasy.

Best Budget: Hask Argan Oil Repairing Shine Hair Oil

Hair oil doesn’t have to be super pricey to work efficiently. Take this affordable little bottle, for example. Its argan oil-infused formula controls frizz and gently detangles hair while strengthening and adding some serious shine. It’s also safe to use on color-treated hair as it’s sulfate- and alcohol-free.

The formula is also pretty versatile, meaning you can apply it before or after styling or use it as an overnight leave-on treatment. What we love most is the brand’s signature scent, which is 100% naturally derived and infused with honey.
Active Ingredients: Mirsalehi honey, dimethicone | Dosage: 1-2 drops | Free of: Sulfates, parabens, phthalates | Size: 0.7 / 1.7 / 3.4 fl. oz | Cruelty-Free: Yes | Byrdie Clean: No

This restorative yet lightweight formula features ingredients that help repair broken bonds in strands to prevent further damage and breakage so you can nurse your hair back to its best state. It also contains hydrating grape seed and fermented green tea oils to improve the feel of your strands. Plus, it protects the hair from future heat styling up to 450 degrees. Impressive much?

Best for Sun Protection: Klorane Protective Oil with Ylang-Ylang Wax
Can be used on damp or dry hair
Not Byrdie Clean
You likely know how important it is to protect your skin from harmful UV rays, but protecting your hair is a real thing, too. That's why we love this product—it's basically sunscreen for your strands. The formula contains built-in UVA and UVB filters and nourishes the hair as it helps protect it against salt and chlorine. Also nice? The formula is waterproof, so it’ll keep hair protected while you swim. Plus, it smells like summer in a bottle, thanks to its warm sand, coconut milk, and ylang-ylang scent.

Nourishing, non-greasy formula
A little goes a long way
With each use of this deeply restorative treatment, argan oil (rich in vitamin E, antioxidants, and essential fatty acids) and linseed extract (also packed with fatty acids) nourish hair. However, the formula is also non-greasy and fast-absorbing, so you won't have to worry about weighing your hair down. It’s best used on clean, damp hair right before styling or as a touch-up throughout the day. Plus, one whiff of the spicy amber and warm floral scent, exclusive to Moroccanoil, will instantly transport you.

Brittle hair, beware. This repairing oil is coming for you—but in a good way. Certified organic buriti oil, harvested from the “tree of life” in Brazil, instantly quenches and restores thirsty, weak hair. You’ll also find that there’s no silicone in this formula, so just a few drops are all it takes to revive dull tangled strands with no greasy or sticky residue left behind. Plus, the whole formula is 90% natural (sourced from plants, non-petroleum minerals, and water), and doesn't contain any sulfates, parabens, or phthalates.

A little pricey
Using a blend of six nourishing oils such as coconut, argan, and macadamia, this hair oil has a super non-greasy texture that's immediately absorbed, adding needed hydration and softness and removing any pesky frizz. It's formulated with UV filters that protect strands from the damaging effects of the sun while also protecting against breakage and heat styling.

Best for Color-Treated Hair: Leonor Greyl l'Huile de Leonor Greyl Pre-Shampoo Treatment
Product may solidify in cold temperatures
Our former editorial director, Faith Xue, calls this oil a life-saver for her platinum blonde hair. Considered a protective pre-shampoo, it’s best applied on dry hair—either right before you hit the beach or pool, or before you spend the day out in the sun. Let the product, which contains a powerhouse blend of botanical oils, sit for a few hours so the product can completely coat each strand, essentially creating a barrier to guard your hair from outside forces (like chlorine and salt water). At the end of the day, rinse it out.
Active Ingredients: Vegetable oils | Dosage: Dime-size amount | Free of: Sulfates, parabens | Size: 3.2 fl. oz | Cruelty-Free: Yes | Byrdie Clean: No

Formulated to work for all hair textures and types, it's great for locking in moisture, combatting frizz, and reducing blow-dry time. It also moonlights as a heat protectant, preventing any future damage from your blow dryer or hot tools. The formula is weightless, so it won't leave your hair feeling sticky or weighed down. Plus, it has the most incredible fresh orange and rose scent.
Active Ingredients: Cyclopentasiloxane | Free of: Sulfates, parabens | Size: 3.4 fl. oz | Cruelty-Free: No | Byrdie Clean: No
What Our Editors Say
"My bleached, fragile hair drinks up oil like it's water, and this one from Redken is a newfound favorite. Whenever my ends are looking parched or thirsty, I add a dime-sized amount to my palms and smooth it through my hair. The result is instant—my hair looks shinier and healthier (and feels softer) immediately afterward. Plus, I like that I can use as much as I want without it feeling greasy or heavy." —Faith Xue, former Byrdie Editorial Director
Best Argan Oil: Josie Maran 100 Percent Pure Argan Oil
Also for skin and nails
Pure argan oil
A little pricey
This best-selling argan oil checks all the boxes: hydrating, nourishing, clinically tested, and it has no added ingredients. Tame frizz effectively by applying a small amount from midshaft down, focusing on the ends as you spread out the product. What we love about this versatile oil is that you can literally use it anywhere—your hair, scalp, face, and body. Not only is it multifaceted, but it shortens your routine, too.

Best for Protective Styles: Taliah Waajid Ditch The Itch Anti-Itch Serum
Soothes an itchy scalp
Could be more moisturizing
If you're wearing braids, extensions, or other protective styles, it's important that you keep both your hair and your scalp healthy. This hydrating oil helps tackle itch and other issues from the root (literally) with an easy-to-use applicator that goes straight to your scalp. The formula is super calming to stop itch on contact and seal in moisture. Plus, it contains biotin to protect hair elasticity and promote thicker, fuller growth.
Active Ingredients: Sesame seed and basil oils, menthol | Free of: Sulfates, parabens | Size: 2 fl. oz | Cruelty-Free: Yes | Byrdie Clean: No
Hands down, the Ouai Hair Oil is an absolute must. Formulated with a blend of African galanga root extract and ama, borage, and baobab oils, this lightweight hair oil works to completely eliminate frizz and tame unruly hair. Plus, it doubles as a hair perfume with the prettiest gardenia and violet scent. We’re also big fans of the L'Oréal Paris Elvive Extraordinary Oil Deep Nourishing Treatment, a rich, multitasking hair treatment formulated with argan and camellia oils. It can be used as a pre-shampoo treatment, a styling treatment, and a finishing oil to lock in moisture and keep frizz at bay. Looking for something weightless? The VERB Ghost Oil literally disappears into the hair upon application, helping to smooth and detangle it. The results? Shiny, frizz-free hair with no heavy residue.
What to Look for in a Hair Oil
Nutrient-Rich Plant Oils
When it comes to the very best oils for your hair, hairstylist Shelly Aguirre recommends a handful of natural, plant-based oils. “Coconut oil is very conditioning and is rich in vitamins and minerals that help heal the hair,” she says. She explains that it's also great for protecting against heat damage, making it a top choice for drier textures. In addition to coconut, she recommends nut-derived argan and almond oils, both of which are rich in protein and antioxidants. Castor oil is another favorite for thicker, curly hair and is great used as a pre-shampoo treatment.
Avoid Mineral Oil
While the above oils are all great choices for deeply nourishing the hair, there are some oils that shouldn't be slathered all over your scalp. Case in point? Mineral oil. Already considered to be an iffy ingredient in the beauty world, it’s known to cause excess buildup, which will not only lead to scalp issues down the road but will leave the hair feeling heavy and weighed down.
Some hair oils smell heavenly, but if your scalp is particularly sensitive and prone to itchiness, it's best to avoid formulas with any added fragrance—even natural ingredients like essential oils. This can lead to irritation, inflammation, and more serious scalp breakouts. If you’re loving the scent of a particular hair oil but you aren't sure how your scalp will react, be sure to only apply it your ends, keeping it as far away from the roots as possible.
Can you use a hair oil on oily hair?
Aguirre says that experts have pretty mixed opinions when it comes to applying hair oil to oily hair. “There are a lot of conflicting views on oil for oily hair,” she says. “Most dermatologists won’t recommend applying oil on oily scalps, while some haircare companies do."
She goes on to explain that oil can clog pores, which isn’t good long-term, especially if you're prone to scalp blemishes and breakouts. At the same time, the cause behind an oily scalp will vary from case to case, and it can sometimes be hard to diagnose. “I would recommend asking your professional stylist what steps to take and which products to use if you're dealing with an oily scalp,” she says.
Do hair oils cause scalp acne?
Scalp acne occurs when hair follicles get clogged with oil, dead skin cells, or product buildup, and several different factors can cause it. “If you’re experiencing occasional scalp acne, that’s totally normal—it may just be hormonal,” says Aguirre. However, she mentions that more frequent breakouts can be caused by something internal, like stress, or they can be triggered by the products you’re using—hair oils included. Hair oils and other products that contain a lot of oil can contribute to scalp buildup, causing acne or exacerbating an existing breakout. If your scalp is already prone to breakouts, be sure to avoid applying any oil-based products too close to the scalp or roots.
How do you apply hair oil?
Hair oils can be used in a multitude of ways depending on the formula, weight, and your hair’s specific needs. Hair can be soaked in oil as a deep-conditioning pre-shampoo treatment, or it can be applied to wet hair pre-blowout as a shine-boosting styling treatment. Lightweight formulas can also be used on freshly styled hair to tame frizz and lock in shine.
If you’re not using hair oil as a pre-shampoo treatment that you'll be washing out, Aguirre recommends avoiding applying it too close to your roots and scalp—especially if your hair is already on the oilier side.
When should you apply hair oil?
Hair oil can be applied at any time to wet or dry hair, again, depending on the formula, weight, and your hair's needs. Aguirre prefers to apply hair oil on damp hair before a blowout. “Depending on the density, less might be more,” she adds. “Your brush will glide through the hair easier, and it will act as a protectant from the heat of your dryer. It also adds shine and body."
