It might also help prevent hair loss, dandruff, and premature graying. When you wash your hair, add a few drops of rosemary oil to your shampoo. Start with two or three drops per application of the shampoo product (such as a sample of the shampoo the size of a U.S. quarter). Dandruff is a common scalp condition that causes the skin on the scalp to flake. According to a 2022 Combinatorial Chemistry and High Throughput Screening review, essential oils have a strong potential to be developed as anti-dandruff products. “Using rosemary oil directly on your hair strands can provide additional benefits such as improving hair texture, reducing split ends, and enhancing shine.
Best Rosemary Oil Products to Try
If you have very fine hair and/or an oily scalp, James advises using rosemary oil once a week as a scalp treatment and washing it out of hair immediately to avoid any greasiness. Although considered relatively safe to use, rosemary oil isn’t recommended if you’re pregnant or breastfeeding (chestfeeding). Warning labels on some 100% rosemary products warn that use could affect the fetus or lead to a miscarriage. Coarse hair may be better able to handle an application of rosemary oil.

Rosemary Oil for Hair Growth: Does It Work? A Dermatologist Weighs in
You can also add 2 to 3 drops directly to any hair product when you apply a dollop of it on your palm before use. Carnosic acid, an active ingredient in the plant, healed tissue and nerve damage in one study. This ability to heal nerve endings may rejuvenate nerves in the scalp too, in turn possibly restoring hair growth. Helen Reavey, board-certified trichologist and founder of Act + Acre, recommends leaving the oil in your hair for “at least 30 minutes,” and you can absolutely leave it in longer. “I recommend a longer amount of time as it can be used as a leave-in treatment,” she says. Rosemary oil can be applied to the scalp and massaged in, or even applied to the air and covered with a shower cap and heating cap for a soothing treatment.
Massage, rinse, repeat
Whether you’re using your fingers or a massage tool, getting hands on will amp up blood circulation in the scalp, not to mention it feels nice and relieves stress. Apply rosemary oil to your scalp and gently massage it in using soft, circular motions. “Since the evidence is sparse, it’s not known what exact dose and frequency rosemary oil should be used at,” says Han. She recommends applying an oil to the scalp one or two times a week and leaving it on overnight, or sudsing up every one to two days if you’re using a shampoo.
However, it's important to note that many dermatologists recommend 5 percent minoxidil for hair loss, not 2 percent. However, if you find minoxidil irritating on your scalp, you might wanna try rosemary oil, which caused significantly less scalp itching in the study. A 2015 study found that rosemary oil may be a useful treatment for androgenic alopecia. The participants of the study showed a significant increase in hair count after 6 months of using rosemary oil. The overall result of the study provided evidence that rosemary oil may be effective for certain hair growth. Not enough is known about the safety of using rosemary essential oils while pregnant or breastfeeding.
If you get it in your eyes, rinse your eyes with cold water and seek medical attention if the effects worsen or do not improve. If your shower drain is any indication, hair shedding is a common experience. The big difference between hair shedding and hair loss is the rate at which hairs fall out without growing back. Lastly, Rubin advises that rosemary oil possesses a distinct and potent aroma that may not be everyone's cup of tea. While it's not a dangerous side effect, it's worth considering before dropping your hard-earned funds on any rosemary oil formulation, especially if you prefer milder or fragrance-free formulas. This non-invasive treatment uses lasers directed at and not the hair strand scalp to encourage cellular activity and hair regrowth, offering a high-tech solution for those seeking alternatives to topical treatments.
Risks and Side Effects of Rosemary Oil
Both products had comparable results, but the rosemary oil was actually more beneficial, as it was less irritating to the scalp. While there are a few different ways to make rosemary oil for hair, it’s most commonly done by adding rosemary extract to a carrier oil (castor oil or argan oil), explains Dr. Lal, who recommends using one that is noncomedogenic. However, Dr. Lal tells patients that it's better to buy a product that is already formulated for use in the hair or on the skin to make sure you get the best results. Rosemary oil is also thought to potentially boost blood flow to hair follicles, thus encouraging healthier hair growth, and can also minimize cell-damaging free radicals with its strong antioxidant properties. Plus, it's anti-inflammatory, which is great for anyone who's experiencing inflammation-based hair loss or thinning from stress and/or hormone fluctuations.
Rosemary oil has a lot of benefits that could potentially lead to hair growth down the line, even if it isn't a proven method for growth. Carnosic acid, one of the main ingredients in rosemary oil, is thought to potentially stimulate and heal nerve tissue, according to one 2010 study, which could possibly do the same to your scalp and help encourage hair growth. While essential oils, like rosemary oil, are natural products, they may not be safe for everyone to use. To avoid skin irritation, dilute the oil with a carrier oil or other product before applying it.
They can moisturize your scalp and hair follicles, promote hair growth, and reduce the chances of hair falling out. But that isn’t all—some hair oils even have therapeutic benefits, helping alleviate irritated scalp skin and reducing flaky dandruff. Basically, they’ll make your hair look healthier and stronger overall. Rosemary isn’t just an ingredient to make your quiche sound even fancier; it has natural healing capabilities, too.
To maximize rosemary oil's effects on hair, Reavey suggests coupling the ingredient with other powerhouses. “I also recommend products that contain peptides, stem cells, and ginseng to support hair health from the root and optimize the hair follicle’s function. Our Stem Cell Peptide Treatment contains clinically vetted Grape Stem Cells that create an environment for optimized hair follicle function, leading to thicker-looking hair in just 12 weeks,” she adds. Once you mix the rosemary oil with the carrier oil, massage it into the scalp. If you choose to rinse it out, do so after the solution is on the scalp for at least a few minutes. Using essential oil-carrier oil solution daily in your hair or scalp is generally safe, provided you do not use too much rosemary oil.
These products come highly recommended by Karan Lal, MD, a board-certified dermatologist and director of cosmetic dermatology at Affiliated Dermatology in Scottsdale, Arizona. It’s formulated with rosemary leaf extract, ideal for those looking for a less-potent formula that's easy to use. Dr. Lal mentions that while these products may not be as potent as an oil since they don't have sufficient time to "sit on the scalp and deliver significant effects," but they’re a great starting point — and they smell delightful. To level up their benefits, consider teaming them with a serum or oil. Dr. Ansell recommends doing a patch test (especially if you have sensitive skin) by applying a small amount to your forearm, letting it dry, and monitoring it for 24 hours. "If irritation occurs, gently wipe off the rosemary oil with soap and water," the expert continues, adding that the irritation should subside quickly.
There are three stages of hair growth – anagen, catagen and telogen. Our hair is distributed into these three stages, so we have more or less consistent shedding… but it isn’t completely consistent. Figures 5 and 6 are meant to be for greasy hair and dandruff, but they’re the exact same (well, the formatting is a few pixels off). If you look at the result paragraph above, dandruff should have much lower numbers (16% in the total study population), so Figure 6 seems to be the incorrect one. It’s bad enough if we assume the Month 3 numbers are wrong, but it could actually be the baseline numbers, which are what “significant increase in hair count at the 6-month endpoint” is based on.
Apply the mixture to the scalp and “leave on for an hour before washing,” Doyle adds. A 2016 study found that rosemary affected blood circulation and skin health in rats. If the same were true of humans, then rosemary oil might prevent hair loss by improving hair and scalp health.
