It also gets a stamp of approval from dermatologist Lindsey Zubritskey, MD. “It contains rosemary oil, which is an ingredient proven to help with hair regrowth,” she says. It can also help strengthen your hair follicles.

The formula contains a mix of more than 30 different oils, including castor, peppermint, and lavender oils. It costs less than $10 and you only need to apply a few drops with each use.

Dermatologist Marisa Garshick, MD, counts Kiehl’s Magic Elixir as a favorite. “Containing a blend of avocado oil and rosemary oil, I love that it can be used prior to shampooing, helping to nourish the scalp and hair, improving the overall health of the hair and scalp,” she says. It’s meant to be applied to a dry scalp and left on for 10 minutes before rinsing or washing your hair.

This treatment is intended for all hair types, including fine hair, and doesn’t contain any added fragrance. The oil includes ingredients like rosemary oil and moisturizing avocado oil.

Ceremonia makes efforts toward sustainability, like using packaging made from 30 to 100 percent post-consumer recycled materials. It's a brand that's officially plastic-negative, ensuring it takes out more plastic from nature than it uses in its products, contributing to recycling efforts.

Rave review: “My hair and scalp have been extra dry after having my baby, and I’m starting to lose my hair due to postpartum. Using this treatment has helped me with the dryness and I feel like it’s helping keep my hair loss under control.”

Rthvi’s products are created with the intention of merging Ayurvedic principles with modern science. The brand’s scalp oil combines rosemary, peppermint, and bhringraj oils to promote hair growth and combat dryness. It also contains Indian goosebury (amla) extract, which, according to a 2020 study by Dovepress, stimulates hair follicles to promote hair growth and indirectly block DHT, a hormone linked to androgenetic alopecia (male or female pattern baldness).

The product is designed to be used three times a week and left on for at least three hours before washing your hair, but you can also use it as a leave-in treatment.

Rave review: “I have been struggling with hair thinning and hair fall for many years. I have tried many OTC solutions as well as consulted specialists many times. However I have never seen such promising results as I did with this Revitalize Hair Growth oil. My hair is thicker and I can barely see my scalp anymore.”

The Mane Choice The Alpha Multi-Vitamin Scalp Growth Oil is designed to be used up to once per day, and contains ingredients like rosemary extract and castor oil. It also has tea tree oil, which may enhance the effects of minoxidil (a medication that stimulates hair growth), per a 2013 study by Dovepress.

The oil is one of the more affordable options on this list. Reviewers love its fruity smell but caution that it’s best used before washing, since it’s rather heavy.

Leonor Greyl Régénerescence Naturelle features a blend of 16 oils, some of which are organically grown. The combination is intended to nourish your hair and scalp while promoting hair growth.

For optimal effects, the treatment is designed to be left on for a period of time ranging from 15 minutes to overnight. It’s suited to those who prefer products that are vegan, cruelty-free, silicone-free, and/or made without synthetic ingredients. The oil comes in a vial with a rollerball, allowing for easy, mess-free application.

Rave review: “I love the way this product smells. It's amazing. It also does wonders for my dry scalp.”

Formulated with rosemary oil extract and scalp-friendly ingredients like castor oil, Kitsch Pre-Wash Scalp Oil is designed to loosen buildup before shampooing. It’s naturally fragranced with a calming lavender scent.

The oil is meant to be left on for 10 minutes, which is ideal if you don’t like leaving oil on your scalp for long periods of time. The bottle is made of recyclable aluminum, and the dropper is made of recycled plastic.

Rave review: “After using this serum I did notice that my hair looked healthier and I even thought my hair had a bit more volume the day after. The scent is nice and it’s easy to apply prior to your shower.”

Sarisha’s products are hand-blended in small batches and are cruelty-free and vegan. The brand’s Nourishing Hair & Scalp Oil is a combination of vitamin E and organic plant-based oils, including lavender, peppermint, and rosemary oils.

Rave review: “Makes my waves look beautiful and reduces frizz significantly. Smells divine to boot.”

Wild Growth Hair Oil is one of cosmetic chemist David Petrillo’s top picks. It combines ingredients like lavender, peppermint, castor, and jojoba oils. “Jojoba oil is often used to moisturize the scalp and hair,” says Petrillo. “While there is limited research on its direct impact on hair growth, it may contribute to overall hair health.”

You’re only meant to use a few drops of the oil one to three times per week, so the four-ounce bottle can last a while. You can add it to shampoo, hot oil treatments, co-washes, or apply it on its own after washing your hair. The oil is on the richer side, making it ideal for those with thick hair. The brand also makes a more lightweight version.

Rave review: “My main goals was to grow and strengthen my hair, I have been using this oil for a month and I can honestly say that I have noticed a great difference. Not only did my hair grow but it feels stronger, shinier, and it stopped falling.”

Mauli Rituals encourages applying its Grow Strong Hair Oil with a head massage. You can purchase the oil with or without a comb, which you can use to stimulate your scalp.

The brand recommends using a few drops of oil twice a week for six weeks, then once per week. You can leave it on from 20 minutes to overnight before washing your hair, or use it on your strands to tame dry ends. It’s filled with potentially beneficial plant-derived ingredients, like amla and bhringraj oils.

Rave review: “I have fine naturally grey hair which is glossy and shiny thanks to this oil. There's a lot of regrowth too which is great.”

Camille Rose Rosemary Oil Strengthening Hair Drops are targeted to people of all hair types who want to improve growth and avoid dryness. Along with its namesake ingredient, rosemary oil, the formula contains amla extract and peppermint, castor, and lavender oils.

The brand suggests applying two to three drops of the oil to wet or dry hair, daily or as needed, and leaving it on. In addition to applying it to your scalp to promote hair growth, you can use it on the lengths of your hair to reinforce your strands, minimizing breakage.

Rave review: “This oil along with the shampoo and conditioner has improved my itchy flaky scalp as well as growth/ length retention. I mainly use the oil when I wear braids because of the thickness of the oil but other than that I’d recommend using buying and using this product.”

Thanks to the potential of ricinoleic acid to promote hair growth by boosting circulation, pure castor oil is a solid option, according to Petrillo. Plus, it can serve multiple functions, since castor oil is a popular DIY lash serum alternative.

This pure castor oil is USDA-certified organic and ISO-certified, meaning the company meets various quality assurance standards. It’s available in four different sizes, with the smallest ringing in at just under $7.

Rave review: “I use this organic product on my natural hair. The moisture holds longer in my hair and keeps hair in place as well. Also have seen hair growth and thicken since I began using this product.”

This organic oil contains eight ingredients selected to boost hair growth, including rosemary, tea tree, lavender, and peppermint oils. It also has green coffee bean oil which contains caffeine, an ingredient that may boost hair growth by counteracting DHT’s effects on hair follicles.

The oil is meant to be used as a pre-shampoo treatment and is intended for all hair types. The brand hand blends and bottles its products in small batches in California.

Rave review: “I’ve been using this hair oil for almost a year and I’ve noticed improved hair growth and overall hair health. I love my hair care routine of oiling before washing and have recommended this oil to others as well.”

Dr. Garshick considers Briogeo Curl Charisma Organic + Cold Pressed Castor Oil a contender for the best castor oil for hair growth. “The cold-pressed castor oil contains humectants, vitamin E, and omega fatty acids, which work together to keep the hair healthy and hydrated,” she says. “It can be used on the hair, eyebrows and eyelashes.”

The pure castor oil is a vegan, cruelty-free, organic option. It’s certified Fair Trade for Life, signifying that the company uses environmentally friendly practices and safe working conditions throughout its supply chain.
