Rosemary is the ingredient du jour, but you should consider a few things before adding it to your routine. “Rosemary extract/oil is extremely concentrated, so it’s generally recommended to dilute it with a carrier oil (such as argan oil, or jojoba oil) before applying it directly to the hair and scalp,” says Reavey. A byproduct of perifollicular fibrosis (scalp scarring around hair follicles) is a reduction in blood flow to our hair follicles.
Use Rosemary Oil Products
Some creators are boiling rosemary leaves, concocting custom rinses and sprays at home. Others are taking the more convenient route of snagging a ready-made product from their local beauty supply store. Because it’s a pretty potent ingredient, for some, excess use of rosemary oil may lead to some itching and burning, says Holdsworth.

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. Researchers believe rosemary oil works by stimulating hair growth and blocking the effects of a type of testosterone, which shrinks hair follicles and leads to hair loss. A study from 2022 found evidence that rosemary oil can help with hair growth. Here, researchers looked to formulate oleogels (gels made from vegetable oil) containing two essential oils (cedarwood and rosemary) alone and in combination to evaluate their effects on hair growth in rat models. To maximize rosemary oil's effects on hair, Reavey suggests coupling the ingredient with other powerhouses.
What are the benefits of rosemary oil for hair?
Studies have shown that rosemary oil for hair has promising positive effects for people with male pattern baldness and alopecia areata [1-3]. However, a single study doesn't meet the standard of rigorous testing. Plus, Kingsley points out that this study had too small a sample size to be definitive and that its subjects were all men. However, this stimulation can be attributed more to the massage than to the rosemary oil itself. To promote hair growth, opt for a scalp serum that nourishes your follicles. Like peppermint essential oil (also used to promote hair growth), rosemary essential oil strengthens circulation.
How to Use Rosemary Oil to Grow Hair, According to Experts
So, why does rosemary oil act like Miracle-Gro® when rubbed onto your scalp as a highly concentrated extract? Much of the credit goes to carnosic acid, a phenolic chemical compound in the plant. To prevent skin irritation or other side effects, avoid oils that contain fragrances and other artificial ingredients. One of the easiest ways to use rosemary oil for hair growth is to purchase shampoo with rosemary oil already in it. You will want to pick a shampoo with a higher rosemary oil concentration.

This editor-approved oil contains over 30 essential oils and nutrients in one bottle, but the VIP is rosemary oil. While applying the pure oil will probably be more effective, you can also put some drops of rosemary oil to your shampoo and let it sit on your scalp for a few minutes to see if the benefits apply there too. While clinical photos are limited, some rosemary oil users have documented their own hair regrowth journey after applying rosemary oil. Let’s take a look at some of the self-reported results of using rosemary oil for hair growth. Topical use of rosemary oil is generally safe, although allergic reactions and skin irritation are possible. You should dilute the oil with a carrier oil before using it in your hair.
However, you will want to do a patch test (applying it to a small area to observe for a reaction) before applying it more generally to the skin. While typically reserved for elevating the flavor profile of a dish, rosemary can work wonders for hair suffering from damage or stagnant growth. “Rosemary oil is a stimulating ingredient that works to promote hair growth while stimulating blood flow, ultimately strengthening the hair follicle,” says Helen Reavey. Beth Gillette is the beauty editor at Cosmopolitan with five years of experience researching, writing, and editing hair stories that range from shea butter for hair to shampoos for oily hair. She’s an authority in all hair categories, but is an expert when it comes to rosemary oil for hair. After interviewing experts and researching up-to-date info on rosemary oil for hair, she tested it for two months on her own short, fine hair.
However, for any potential hair growth benefits, the application must be regular and intentional. "When using rosemary oil for hair regrowth, I recommend nightly application every day for at least the first six months," Markowitz explains. In addition to the direct application of rosemary oil treatments, many shampoos and conditioners contain rosemary oil that you can incorporate into your beauty routine. Rosemary oil is one of the most effective essential oils for hair growth.
Similarly, there has been no analysis of whether rosemary oil is safe to use alongside minoxidil or other hair growth medications. According to Dr. Kobets, there is some evidence in the literature to suggest that rosemary oil can help hair growth by stimulating hair follicles with cytokines and growth factors. You can also add essential oils for your preferred health and beauty benefits. These may incorporate a mixture of baking soda, coconut oil, essential oil, and possibly other oils. While rosemary oil is often hailed as an effective ingredient for promoting hair growth, these are the proven benefits supported by clinical evidence.
“I’ve had progress with a rosemary oil spray (witch hazel, tea tree oil, lavender, and rosemary), spray on a morning close to the roots, and wash that night. After twelve weeks, the Rogaine + once weekly dermarolling sessions resulted in 4x the hair regrowth of just Rogaine alone…. And since the triggers of chronic scalp inflammation are elusive, the best way we currently know how to do this is to reduce the proteins and enzymes involved in the pro-inflammatory process. In an acute injury, cytokines and COX-2 enzymes eventually go away.
One such benefit is its use in promoting hair growth and preventing hair loss. Two different hair loss treatments; yet two similar mechanisms of action at play. And when we compare those photo sets to our one-off case study, it’s harder to deny that these mechanisms of action may promote a strong, synergistic hair regrowth effect. While rosemary oil is typically used in perfumes and foods due to its pleasant scent and unique flavor, its benefits also extend to medicine. For decades, cultures around the word have used rosemary oil to treat inflammatory conditions ranging from arthritis to asthma to nerve inflammation.
And fortunately for us, these specific compounds within rosemary oil have a variety of pro-hair effects. Unfortunately, there was no control group in this study, so we don’t know much of that hair count increase we can attribute to normal seasonality… and how much we should truly attribute to the rosemary oil or 2% minoxidil. All that goes to say is, if you’re dealing with hair loss, get yourself to a dermatologist first, take their advice and use rosemary oil and its related products as a supplement on top of authorized treatment. Meanwhile, antioxidants in rosemary oil can help reduce inflammation in the scalp, while glycolic acid can aid with skin cell turnover. However, if a patient wants a natural remedy, Dr. Turner will recommend tea tree oil over rosemary. If used properly, rosemary oil shouldn’t cause irritation, however, Christen notes that skin irritation and contact dermatitis could occur.
Using too much of it may damage the hair follicles, causing hair loss instead of hair growth. Children and infants may be more sensitive to the concentration of essential oils. This means they may need to be further diluted or avoided altogether. Speak with a healthcare professional before using oils on children.
