If you've noticed that your hair hasn't been looking quite as full and voluminous as it once was, you're not alone. According to the Cleveland Clinic, it's estimated that more than 50 percent of women will experience noticeable hair loss — and there are so many reasons why it can happen. Everything from hormones to diet and stress can affect the appearance and quantity of your hair.
While there are plenty of great products on the market that can help you get thicker and healthier locks, some come with a high price tag and a risk of skin irritation. But, there is a more natural and affordable option that may do the trick.
One dermatologist went viral on TikTok in July of last year after he posted a video saying that rosemary oil could be as effective as Rogaine. As evidence, he cited a 2015 study that showed that the essential oil had the same effect on growth as minoxidil (the generic version of the treatment) and it was less likely to cause scalp itching. Since then, many other users have posted their own success stories on the app — and videos featuring the #rosemaryoil tag have garnered nearly 125 million views.
So we tapped Dr. Michelle Henry, a board-certified dermatologist in New York City, to get all the details.
Does rosemary oil help with hair growth?
While there are a few essential oils that can help to stimulate hair growth, Henry said that rosemary oil tends to be a top choice. "Rosemary oil is equivalent to 2.5 percent minoxidil, which is pretty impressive," she said. "It's something that we can use during pregnancy or for patients who just don't want to use minoxidil or are intolerant to it," she said. Because it's non-toxic and tends to be well-tolerated, almost anyone could incorporate it into their routine. "It's safe to use as long as you appreciate the scent — which many do," she added.
While experts still aren't entirely sure how it works, the belief is that it improves circulation in the area, which can lead to cellular turnover and growth, Henry said. As an added bonus, it's also anti-inflammatory, and because inflammation plays a big role in a lot of hair loss conditions, like central centrifugal cicatricial alopecia (CCCA) or alopecia areata, it can be a helpful tool in managing and treating those issues.
How to use rosemary oil for hair
To use it, Henry suggests mixing the oil with a carrier oil (like grapeseed or coconut oil), which will help your skin better tolerate the ingredient. Massage the concoction onto your scalp twice per day.
Another option is to use products that feature the oil as an active ingredient, Henry said.

"I have been using this shampoo for two years and absolutely love it," wrote one verified Amazon reviewer. "I have super fine/thin hair.
