There’s been quite a lot of buzz surrounding the benefits of using rosemary oil for hair growth, and whether or not it can be useful for slowing down shedding across the scalp. The answer seems to be highly positive—whether you’ve seen TikTok videos of people raving about how the ingredient has been transformative for their hair loss, or have read glowing reviews from shoppers about a given rosemary oil for hair, it’s clearly working for many folks. But if you’re personally wondering how to use rosemary oil for hair growth and whether or not it’s worth exploring, we got some legit feedback from a professional dermatologist to share. 

Dr. Brian Abittan, Director of Skin and Hair Rejuvenation and Director of Hair Transplantation at Mount Sinai Health System, shared that there are two studies that show rosemary oil has the potential to help grow hair. “While certainly more trials and data are needed, rosemary oil does seemingly have potential to help with hair growth,” Dr. Abittan told StyleCaster.

While he says that the mechanism of action causing hair growth is not fully understood yet, it seems that there are multiple ingredients of rosemary oil (rosmarinic acid, caffeic acid, camphor, etc.) which may contain anti-inflammatory, antioxidant and anti-microbial properties. “Together these may help contribute towards hair growth.”

But how often should one apply rosemary oil to the scalp? Dr. Abbitan says it depends on the formulation being used, but most options out there will advise being applied once daily across areas of loss to see results.

If you’re wondering if there are instances in which to avoid using rosemary oil, Dr. Abbitan says this can ultimately depend on the formulation and concentration of a given oil, since it can sometimes be irritating to the scalp and cause contact allergies. “It is important to note that there are many different types of hair loss and that rosemary oil may work better for some types than others.” You may want to have your scalp issues evaluated by a dermatologist to determine your specific type of hair loss (and whether or not rosemary oil is a viable solution), should you have any reservations.
