16 Best Hair Oils of 2024 for Your Sleekest Strands Yet

Key Ingredients: Moringa oil, argan oil, bamboo extract | Who It’s For: People with frizz, flyaways, or fine hair

Best for Scalp: Mielle Organics Rosemary Mint Scalp & Hair Oil

Why It’s Worth It: The Mielle Organics Rosemary Mint Scalp & Hair Oil became super popular on TikTok for its effective, soothing, and conditioning natural oil blend. Along with rosemary oil (which may stimulate the hair follicles and support healthy hair growth), the key ingredients in this moisture-sealing cocktail are castor oil, antibacterial tea tree oil, and coconut oil to boost shine and softness while relieving the scalp of irritation and dryness.

Editor Tip: While it’s billed as a scalp treatment, you can use it to mend split ends.

Key Ingredients: Castor oil, tea tree oil, coconut oil | Who It’s For: Anyone seeking scalp benefits

Best for Heat-Styling: Olaplex No.7 Bonding Oil

Why It’s Worth It: Like its predecessors in the Olaplex line, the brand’s No. 7 Bonding Oil is designed to help hair that’s been through it all — heat-styling, chemical-styling, hair-coloring — you name it. Olaplex’s beloved hair oil contains grapeseed oil to infuse damaged hair with much-needed moisture, but its bond-repairing properties come from bis-aminopropyl diglycol dimaleate. This ingredient, found in all Olaplex products, works to repair broken disulfide bonds so your hair will feel stronger, healthier, and less prone to damage.

Editor Tip: The bottle dispenses a small, dosed amount at a time, but the formula is very concentrated so that’s all you should need.

Key Ingredients: Bis-aminopropyl diglycol dimaleate, sunflower seed oil, moringa seed oil | Who It’s For: People with weak or damaged hair

Best for Shine: Gisou Honey Infused Hair Oil

Why It’s Worth It: The delectable Gisou Honey Infused Hair Oil smells good enough to eat (please don’t), but that’s not the only reason we’re constantly repurchasing this 2023 Best of Beauty Award winner. The star ingredient, Mirsalehi honey, also acts as a humectant, which draws moisture to the hair shaft, creating a more lustrous head of hair and a frizz-free look in the process.

Editor Tip: JSYK, the honey is harvested from the founder’s very own bee garden.

Key Ingredients: Honey, coconut oil, sweet almond oil | Who It’s For: Those with dull, dry, or damaged hair

Best for Damaged Hair: K18 Molecular Repair Hair Oil

Why It’s Worth It: A winner in the Splurge category of the 2023 Best of Beauty Awards, K18’s Molecular Repair Hair Oil works to address frizz on two levels: First, by reversing structural damage caused by heat styling and salon treatments, and second, by nourishing hair with natural lipids, like avocado and sunflower oils. It also works to help prevent future damage, too, by giving heat protection up to 450 degrees.
