The 10 Best Hair Growth Oils of 2024

Key Ingredients: Rosemary, mint, biotin | Size: 2 oz

Why we chose it: With consistent use, we’ve heard wondrous things about this formula, including less hair fallout, stronger, healthier hair and scalp, and faster growth. One thing to note: Because this is a scalp oil, it must be rinsed out, or it’ll leave your hair and scalp pretty greasy. We recommend applying this at night, leaving it on while you sleep, and washing your hair in the morning.

What the experts say: Dr. Graf likes to recommend this oil from Mielle Organics because it combines the power of rosemary oil, along with 30 other essential oils and nutrients to encourage hair growth. “It’s also infused with biotin, an ingredient that may help stimulate hair regrowth,” she explains.

Key Ingredients: Caffeine, tetrapeptide, ginseng | Size: 3.3 oz

Why we chose it: In this formula, you’ll find ingredients like peptides, ginseng, and caffeine, which can help promote hair growth while rebalancing and conditioning your scalp. One of the things we love about this pick is that it comes in a spray bottle. Most hair growth oils and serums come in a dropper, in which you must drop the formula onto different areas of your scalp and then rub it in. This can get messy and time-consuming. With this product, simply spray it into a dry scalp, massage it in, and then sleep with it overnight before washing it out.

What the experts say: “I highly recommend and love this product on so many levels,” gushes Yates. “The combination of peptides, plus natural actives, support optimal scalp health and follicle fitness.”

Key Ingredients: Redensyl, procapil, baicapil, castor oil | Size: 2 oz

Why we chose it: Have you ever tried a hair growth serum or oil and felt you needed to scrub your scalp immediately? Fret not because this pick from The Ordinary is lightweight enough to absorb undetected into your scalp. We love that this formula is affordable, but we wish it came in a bigger bottle, as it’s easy to run out fast.

What the experts say: “I recommend this pick to my patients because it’s infused with peptides, hair actives, and castor oil to help increase hair density and fullness,” explains Yates.

Key Ingredients: Redensyl, probiotic, rosemary, clary sage, peppermint | Size: 4 oz

Why we chose it: Dr. Graf likes this pick from The Nue Co. to help boost hair thickness because of the patented follicle technology. It’s likely you’ll notice less shedding and new hair growth after using this formula continuously. Note: Some folks have complained that this dries out their scalp, so if you have a super dry scalp, you might want to opt for something else.

What the experts say: “Redensyl complex protects hair follicles and supports new growth, while rosemary stimulates scalp circulation and follicle support,” Dr. Graf explains. “Also, the included probiotics support a healthy microbiome, too.”

Key Ingredients: Passion fruit oil, castor oil, aloe vera | Size: 2 oz

Why we chose it: Loaded with oils like meadowfoam seed oil, chia seed oil, castor oil, and many others, this pick not only helps promote hair growth but also reduces product buildup and balances and nourishes the scalp. It’s silicone-free and can be used about 10-15 minutes before you hop in the shower and wash it out with your favorite hair growth shampoo. We love how much this product reduces itchiness and flakiness on the scalp, promoting a healthier environment for hair growth.

What the experts say: “Castor oil is mentioned for hair growth. However, it may not agree with some hair types,” warns Dr. Graf. This is a solid option for those with thick or curly hair.

Key Ingredients: Camellia sinensis, caffeine, copper peptide, serenoa serrulata | Size: 1.01 oz

Why we chose it: For the guys who are starting to bald or just want to prevent hair loss, this pick from Revivv is a great option. Formulated with the brand’s proprietary blend of moisturizers, antioxidants, and other hair-nourishing compounds, this roll-on can be applied all over the scalp without leaving hair feeling greasy, wet, or weighed down. The biggest annoyance with this product is that you must use it twice daily to see results. Applying this twice a day might be worth it for those who crave fuller, thicker hair.

Key Ingredients: Tea tree, peppermint, eucalyptus, caffeine, copper tripeptide-1 | Size: 1 oz

Why we chose it: According to Dr. Graf, this scalp serum from Divi includes oils like tea tree, peppermint, and eucalyptus to help with hair growth and soothe the scalp. We like that this is a no-rinse scalp serum that doesn’t weigh down your hair or make your scalp look greasy. Unfortunately, the formula in the bottle seems to run out quickly, which is a bummer because the cost of the product is a bit on the higher side.

What the experts say: “The formula includes ingredients like caffeine, an anti-inflammatory ingredient that can help prevent hair loss, and copper tripeptide, which can promote thicker hair growth,” Dr. Graf says.

Key Ingredients: Varies on customizations | Size: 1.7 oz

Why we chose it: Both Dr. Graf and Yates recommend this pick from Prose because you can customize it to your hair’s specific needs. For example, if you are suffering from hair loss you can indicate that in your questionnaire, and the brand will include ingredients that promote hair growth in your custom oil. You can use this product on both wet or dry hair, but if you’re applying it to your scalp, we recommend applying it at night and then washing it out the next morning. This pick is on the pricier side, but it’s customized to your unique needs, so we think it’s worth the cost.

What the experts say: “I also like that it’s free of all the ingredients you should avoid in hair growth oil, like phthalates, parabens, and sulfates, too,” says Dr. Graf.

Key Ingredients: Castor, safflower, olive, jojoba, and grapeseed oils | Size: 0.48 oz

Why we chose it: This hydrating serum contains luxe oils like castor, safflower, olive, jojoba, and grapeseed to nourish both your hair and scalp and help promote growth. We love that it’s a light oil that can be left on for five minutes or overnight, depending on how much time you have. The formula contains ashwagandha to strengthen your roots and hair follicles, as well as dashmool to calm an irritated scalp, too. Unfortunately, this formula is pretty scented and has added fragrance, so if you are really sensitive to fragrance on your scalp, you might not like this option.

Key Ingredients: Turmeric, biotin, caffeine | Size: 1 oz

Why we chose it: Don’t be fooled by the cutesy bottle—this formula packs a mean punch against hair loss. It includes an array of effective ingredients, including turmeric, which is an anti-inflammatory that enhances hair density, mung bean, and red clover, which blend for scalp health and hair texture. The biggest complaint with this pick is that the bottle tends to leak a lot, so be sure you close it tightly before you stash it.

What the experts say: “I recommend this formula to my patients because biotin and caffeine stimulate the scalp while fortifying hair,” Dr. Graf explains.
