- Dermatologists claim that this kitchen essential might support hair regrowth in those with androgenetic alopecia, and can reduce dandruff while protecting the scalp from environmental stressors
Humble rosemary has gained a lot of hype on TikTok for its hair care properties, and the hashtag #rosemaryoil has garnered a whopping two billion views on the platform.
Rosemary oil stimulates hair growth at the follicle
Not only did rosemary oil help stimulate hair regrowth, but it also made people’s scalps less itchy than Rogaine did several months into the study.
“The bottom line is, yes, it does seem to work,” Dr. Shilpi Khetarpal, a dermatologist, told Cleveland Clinic. “The study really prompted people to look at rosemary oil for hair growth. It became much more common in over-the-counter products after that, too.”
The key ingredient in rosemary oil is carnosic acid, which has both anti-inflammatory and antioxidant properties, and appears to heal damaged nerves and help with blood circulation – fostering new hair growth when applied to the scalp, according to Cleveland Clinic.
Increased blood flow “delivers oxygen and nutrients and prevents damaged hair follicles that lead to hair loss,” Dr. Michelle Green, a dermatologist, told Popular Science.
