Rapunzel may have had magic, but these oils rely on science
Forget waiting around for Prince Charming—if you want long, strong, healthy hair, the secret isn’t in a fairytale. It’s in the right oils. Whether your ends feel drier than a group chat left on read or you’re trying to grow out that questionable impulse haircut (we’ve all been there), we’ve rounded up the best oils for hair growth to get you one step closer to your dream locks.
Best oils for hair growth
When it comes to growing longer, stronger hair, patience isn’t the only thing you need. The right oils can make all the difference by nourishing your scalp, strengthening strands, and preventing breakage before it starts. From antioxidant-packed argan oil to the TikTok-famous rosemary oil, here are the best science-backed options to help your hair thrive.
Argan oil
Nicknamed "liquid gold" for a reason, argan oil is packed with vitamin E, fatty acids, and antioxidants that help repair damage and reduce breakage. This Moroccan treasure doesn’t just coat your hair; it actually penetrates the hair shaft to restore moisture and elasticity. A 2013 study we found on Healthline highlights argan oil’s ability to protect against oxidative stress from the sun, a key factor in hair thinning. Plus, its lightweight texture won’t weigh hair down, making it perfect for all hair types, from fine to coarse.
Rosemary oil
If TikTok has taught us anything, it’s that rosemary oil is the reigning champion of hair growth. But this isn’t just internet hype—science backs it up. A 2015 study in Skinmed found that rosemary oil was just as effective as minoxidil (the active ingredient in Rogaine) for stimulating hair growth over six months, without the scalp irritation. Rich in carnosic acid, this essential oil boosts circulation to the scalp, delivering oxygen and nutrients to hair follicles for stronger, healthier strands. Bonus: It also has antimicrobial properties, keeping your scalp balanced and flake-free.
Castor oil
Thick, glossy hair? Castor oil is your go-to. This powerhouse is loaded with ricinoleic acid, a fatty acid known for its anti-inflammatory and scalp-stimulating benefits. A 2022 review in the Journal of Cosmetic Dermatology found that castor oil enhances blood flow to the scalp, which can encourage faster hair growth. Its natural humectant properties also lock in moisture, preventing dryness and breakage. However, castor oil is thick, so diluting it with a lighter oil (like coconut or jojoba) can make the application easier.
Coconut oil
Few oils are as deeply penetrating as coconut oil. Thanks to its rich concentration of lauric acid, it binds to hair proteins, strengthening the hair shaft from within and reducing protein loss. A Journal of Cosmetic Science study found that coconut oil outperformed both mineral oil and sunflower oil in preventing hair damage. Plus, it’s antibacterial and antifungal, helping to keep your scalp healthy. If you struggle with split ends or heat damage, coconut oil is a must-have in your routine.
Olive oil
More than just a kitchen staple, olive oil is packed with antioxidants, fatty acids, and vitamin E, making it a powerhouse for hair health. It deeply moisturizes the scalp, reduces inflammation, and strengthens hair strands to prevent breakage. A body of research suggests that olive oil helps protect hair from damage caused by oxidative stress, a major culprit behind hair thinning. Rich in oleic acid, it also enhances blood circulation in the scalp, creating the perfect environment for hair growth. Plus, its natural emollient properties help smooth frizz and seal in moisture.
Almond oil
Lightweight yet deeply nourishing, almond oil is a go-to for strengthening weak, brittle strands. It’s packed with biotin (aka vitamin B7), magnesium, and essential fatty acids, all of which support healthy hair growth. Research points to a lack of biotin leading to hair thinning, making almond oil an ideal choice for promoting strong, resilient strands. Its anti-inflammatory properties also help soothe an irritated scalp, reducing conditions like dandruff that can hinder growth. Plus, it acts as a natural sealant, locking in hydration without leaving hair greasy.
Jojoba oil
Jojoba oil is unique—it closely mimics the scalp’s natural sebum, making it one of the best oils for maintaining a balanced, healthy scalp. This liquid wax is rich in vitamins B, C, and E, as well as zinc and copper, all essential for hair growth. A 2022 study found that jojoba oil has strong conditioning properties that help repair damaged strands while preventing breakage. Its antimicrobial and anti-inflammatory benefits also keep the scalp clear and hydrated, ensuring optimal conditions for healthy hair follicles to thrive.
Tea tree oil
Tea tree oil is the ultimate scalp detox, making it a key player in hair growth. Known for its antimicrobial and antifungal properties, this essential oil clears blocked hair follicles, reduces dandruff, and helps combat scalp conditions like seborrheic dermatitis. A Journal of the American Academy of Dermatology study found that tea tree oil significantly improves scalp health and reduces itchiness, which can contribute to hair loss. By keeping the scalp free of buildup and irritation, it creates the perfect foundation for stronger, fuller hair. Just remember—since tea tree oil is potent, always dilute it before applying it to your scalp.
Grapeseed oil
Lightweight yet nutrient-dense, grapeseed oil is a hidden gem for hair growth. It’s rich in linoleic acid, vitamin E, and antioxidants, all of which help strengthen hair follicles and improve scalp circulation. Unlike heavier oils, grapeseed oil absorbs quickly without leaving a greasy residue, making it ideal for fine or oily hair types. A study in the Journal of Investigative Dermatology found that procyanidins—antioxidants found in grapeseed extract—can stimulate hair growth by promoting the anagen (growth) phase of the hair cycle. Plus, its anti-inflammatory properties help soothe scalp irritation, reducing flaking and dryness that can hinder healthy growth.
How to use the best oils for hair growth
Using hair oils isn’t just about slathering them on and hoping for the best—there’s a method to the magic. Nourishing your scalp, strengthening your strands, or adding shine to your finished style, the right application makes all the difference. Here’s how to get the most out of these growth-boosting oils.
On your scalp as a treatment
Applying oil directly to your scalp helps stimulate circulation, nourish hair follicles, and create the perfect environment for growth. To use, warm a few drops of your chosen oil (like rosemary or castor oil) between your fingertips and massage it into your scalp using gentle, circular motions. A 5–10 minute scalp massage not only feels amazing but also increases blood flow, encouraging hair growth. Leave it on for at least 30 minutes—or overnight for deeper penetration—before washing it out with a gentle shampoo.
On your strands as a treatment
Oils don’t just work at the roots—applying them to your strands helps prevent breakage, reduce split ends, and boost hydration. For best results, apply a lightweight oil like argan or almond oil to damp hair, focusing on the mid-lengths and ends. If your hair is thick or dry, you can use a richer oil like coconut or olive oil. Let it sit for at least 30 minutes (or even overnight) before rinsing it out. This helps reinforce the hair shaft, keeping it smooth, soft, and less prone to snapping.
In your shampoo
For a low-maintenance way to reap the benefits of hair oils, try adding a few drops to your shampoo. This helps cleanse your hair without stripping away natural moisture—especially useful if you have a dry or sensitive scalp. Choose a lightweight oil like jojoba or grapeseed oil and mix 3–4 drops into your shampoo right before lathering up. Avoid adding oil directly to the entire shampoo bottle, as this can alter the formula over time. This method means your hair gets the moisture it needs without feeling weighed down.
Added to a deep conditioning mask
Boost the power of your favorite deep conditioner by mixing in a few drops of oil for extra nourishment. Oils like olive, almond, or coconut oil enhance hydration, helping your hair absorb even more moisture. Simply add 3–5 drops to your deep conditioning mask, mix it well, and apply it evenly throughout your hair. Let it sit for at least 20 minutes before rinsing. This method is perfect for anyone dealing with dryness, frizz, or damage from heat styling and chemical treatments.
As a stand-alone oil treatment
A pure oil treatment is the ultimate way to give your hair a deep, restorative boost. To do this, choose an oil based on your hair’s needs—coconut for deep hydration, castor for growth, or jojoba for scalp balance. Apply a generous amount to your scalp and strands, making sure every section is coated. Wrap your hair in a warm towel or shower cap and leave it on for at least an hour (or overnight for maximum benefits). Rinse thoroughly and shampoo as usual.
At the end of styling
For a sleek, polished finish, use a tiny amount of oil as the final step in your styling routine. This helps smooth flyaways, add shine, and protect against environmental damage. Rub a drop or two of a lightweight oil like argan or grapeseed oil between your palms, then gently smooth it over the surface of your hair. Be careful not to overdo it—too much can leave your hair looking greasy instead of glossy. This trick is perfect for sealing in hydration and keeping your style looking fresh all day.
