Much to everyone's dismay, long, full hair doesn't appear overnight — as much as you might wish it would. According to Philip B., celebrity haircare specialist, "hair grows half an inch a month," so it takes time and care to grow hair long. That's why there are so many oils and serums on the market created to help hair grow faster. In addition to hair growth treatments made with minoxidil, the FDA-approved hair growth ingredient, and rosemary oil, Aral also suggests products infused with coffeeberry extract to promote healthy hair growth.

There are a few ways to use rosemary oil for hair growth, depending on the formula you’re using and the level of effort you’re willing to put in. If you’re using rosemary oil that’s already mixed with a carrier (like castor oil ), you can drip two to three drops directly onto your scalp, then massage in. (FWIW, I like to use a silicone scalp massager to really ~get in there~, but feel free to just use your fingertips.) But if you’re using pure rosemary essential oil, you’ll need to dilute it first with either another oil or your shampoo. Castor oil does not contain as many polyunsaturated fatty acids (PUFAs) as rosemary oil. PUFAs are a group of fatty acids that are essential for healthy hair growth. According to studies, the reason castor oil can work to induce labor is due to the fact that the ricinoleic acid in the oil can activate EP3 prostanoid receptors in the uterus. Some animal studies have shown that active compounds in the oil attach to the molecules that makes muscles — in both the intestines and uterus — contract. This is why some people apply it not only to hair on their head, but also to eyebrows and eyelashes.My personal favourite out of the two oils is rosemary oil. This is because it’s lighter, and easier to use. I also found I had better results with rosemary oil in achieving glossier and shinier hair. This is actually very easy to do. Because the two main ingredients are oils, they mix together very easily. Castor oil and rosemary oil are two different types of natural oils that people have used for hair growth for thousands of years.

Yes, you can use rosemary oil for hair loss, as long as you manage your expectations. “Rosemary oil has been compared to minoxidil for its ability to improve circulation on the scalp and even encourage cellular turnover,” says Oligee, “which can both improve hair growth and help prevent hair loss,” Oligee says. Plus, rosemary oil has anti-inflammatory qualities that, over time, could potentially help prevent inflammation-based hair-loss conditions, like certain forms of alopecia, Oligee notes.Also, “There is no data regarding use in pregnancy or breastfeeding; therefore, I would avoid it if possible,” advises Dr. Nussbaum. How does rosemary oil compare, if at all, to other oils? Can prevent hair loss: “ Rosemary oil is a potent antioxidant that can fight against free radicals,” says Dr. Gaby Longsworth, Ph.D. scientist, certified hair practitioner, and owner of the blog Absolutely Everything Curly. These molecules destroy cells over time and can ultimately lead to hair loss by damaging the hair follicle. But unlike the previous methods I’ve tried, I decided to dig into the science behind rosemary oil for hair before potentially wasting my money on yet another scalp product. Here’s what dermatologist doctor Yoram Harth, certified trichologist Gretchen Oligee, and cosmetic chemist Krupa Koestline had to say about everything rosemary oil, like how rosemary oil works, if rosemary oil is safe for hair, and how often to use rosemary oil. Keep reading for all the details: What is rosemary oil? Peppermint oil is a good oil to combine with rosemary when making a hair and scalp oil since they both increase blood circulation and nourish the hair follicles. 9.

The oil has a woody fragrance that provides health benefits such improving cognitive function and boosting the immune system. Rosemary oil is a natural oil that is extracted from the leaves of the rosemary plant (Rosmarinus officinalis). It’s used in many skincare and hair care products because it has several benefits for the skin and hair. Jain S, Arora P, Nainwal LM.

It can also help to prevent a dry scalp.

I guess my TikTok algorithm senses that I have perpetually short, fine, thin hair, because it’s constantly feeding me hair growth solutions. And honestly, I’ve tried everything to make my hair grow faster: hair growth vitamins, aloe vera for hair growth, castor oil scalp massages, rice water treatments—you name it. But the only thing I hadn’t yet tried? Rosemary oil for hair, which has hella anecdotal evidence from TikTokers (with a casual 205 million searches), as well as some potentially promising information from small-scale studies that compare its results to minoxidil which is the active ingredient in Regaine. In addition, the full-term women study subjects (between 40 and 41 weeks) who took castor oil had a lower incidence of Caesarean section. Ethically sourced from Spain, the rosemary in this formula helps deep condition hair and boost shine. Another benefit of using castor oil for hair growth is that its antimicrobial properties can help with dandruff and other infections of the scalp. You can use it for this purpose by mixing some of the oil with your shampoo or conditioner. Prevents scalp dryness

Castor oil is completely natural and free of synthetic chemicals (as long as you use pure 100 percent pure oil, of course), yet it’s rich in skin-boosting ingredients like fatty acids. Applying this oil to dry or irritated skin can help to discourage dryness and keep it well moisturized, since it prevents water loss.
