With hair treatments, you usually have to choose between aesthetic or function: A serum smooths; a leave-in conditioner treats. But hair oils can multitask, serving as a styler that tames frizz and boosts shine and as a repairing treatment — all at once. With summer here in its full glory, there’s no product more perfect than that. A good oil can be that effortless leave-in you need for gorgeous hair, whether you are hitting the beach, going to brunch, or bopping around running errands. Many are packed with highly concentrated botanical oils and rejuvenating ingredients, where a teensy drop makes air drying or styling easy breezy. From strengthening formulas that repair damaged strands to featherweight oils that make hair glossy and free of humidity frizzies, the hair oil you need all season long is right here.

For Frizz Control

K18 Molecular Repair Hair Oil

You know a hair oil is legit when it’s created by biotech engineers. Add very impressive third party clinical studies to the mix, and you have a formula that’s basically a smart oil. It reduces frizz at two levels of the hair fiber and adds shine so good that your mirror could never. It also reverses damage that results in breakage and split ends. That’s all thanks to the brand’s proprietary K18PEPTIDE that repairs hair from the inside out, making it visibly healthier and shinier.

For Strengthening Strands

Olaplex No. 7 Bonding Hair Oil

You probably know someone that swears by the reparative wonders of Olaplex treatments (maybe that’s you…) and their new hair oil lives up to the hype. Just like the treatments, this formula fixes broken bonds from heat, chemical, and physical damage with a special strengthening technology. At the same time, vitamin-rich grape seed oil nourishes, and nutritious fermented green tea softens, tames fuzz, and smooths.

For Moisturizing Medium To Thick Hair

Moroccanoil Treatment Hair Oil

This treatment made hair oils a thing way before their time, and it’s still going strong. Especially loved by those with medium and thick hair types, it deeply hydrates and leaves hair glossy and manageable with argan oil and hair-loving linseed oil. It’s as concentrated (a drop goes a loong way) as it’s fast absorbing and won’t grease up hair.

For High Shine On All Hair Types

Fine, wavy, curly, thick, straight — this hair oil leaves all hair types with the same brilliant, sleek finish. In addition to getting hair healthy with a trio of botanical oils, it also prevents color from fading and protects strands from heat damage. And with perfumer grade notes of gardenia, ylang ylang, and white musk, it smells more like a gorgeous fine fragrance than a hair product.

For Extra Hydration

Kérastase Elixir Ultime Hydrating Hair Oil Serum

For as featherweight as this hair oil is, it does a heck of a job at fighting dryness. Precious oils of camellia, procaxi, and argan leave hair supple and gleaming no matter how you choose to use it, and you can use this one multiple ways. In addition to a leave-in on wet or dry hair, it also serves as a conditioning pre-cleanse treatment or as a heat protector before styling.

For A Clean Sheen

Fable & Mane MahaMane Smooth & Shine Hair Oil

Like a supplement for your hair, this Ayurvedic elixir contains a harmony of oils, botanicals and herbs that help hair feel and look its best. Ashwagandha strengthens and conditions, shikakai adds instant shine, and antioxidant-loaded passionfruit oil nourishes and tames frizz on all hair types.

For Intense Nourishment

Gisou Honey Infused Hair Oil

Inspired by the humectant properties of honey, this treatment hydrates, conditions, tames flyaways and breakage and adds beautiful luster. The star ingredient, Mirsalehi honey, attracts and retains moisture for healthy, reflective hair while almond oil and coconut oil tame and strengthen. And yes, it leaves behind the subtly sweet, floral aroma of honey.

For Fine Hair That’s Easily Weighed Down

Briogeo Don't Despair, Repair! Strengthening Treatment Hair Oil

Lots of repair treatments contain heavy silicones that mask damage temporarily and also make it all weighed down and greasy. Briogeo’s uses hero skin-care ingredient ceramides to help reinforce and rejuvenate broken hair fibers on the surface while repairing deep down, too. (In a third party trial, it repaired up to 88% of damage after only two uses!) And you can’t forget about the rose flower and macadamia oils which add silky soft shine.

For The Most Glossy Curls

BREAD BEAUTY SUPPLY Hair Oil Everyday Gloss

Sometimes you just want a reliable gloss for your curls that you can use on the daily. This one works especially well on curly types, delivering all the goods without any grease, in just a couple of drops. Use it on wet or dry hair or before washing — whatever works best for your everyday hair regime. You get shine, nourishment, and scalp and hair health all in one for girlies with the curlies with the helpf of kakadu plum oil, safflower oil, and triglycerides.

For A Hydrated, Healthy Scalp

Adwoa Beauty Baomint Protect + Shine Oil Blend

Hair health starts with scalp health and this oil blend contains ingredients that support the scalp in addition to hair. Pomegranate oil soothes and calms skin while grape seed oil may help block the production of DHT, a hormone that causes hair loss. For hair strands, fractionated coconut oil moisturizes the hair shaft and illuminates hair. Massage a small amount into your scalp daily then use whatever’s left over to smooth over strands: The formula also provides UV protection perfect for summer, and is especially great for curly-hair types.
