On TikTok you’ll find a veritable rosemary oil fan club proclaiming its powers; regrowing edges, thickening hair and lengthening locks is the refrain of countless rave reviews. Spawning long hair might seem a significant ask of a supermarket herb, but the people swear by it – and they’ve got video proof.

Does rosemary oil actually work?
With testimonials touting its efficacy for alopecia and postpartum hair loss, sceptics might wonder whether there are hard facts to support what seems like another fad. As it turns out, there’s actually scientific evidence to suggest that rosemary oil can be as effective as the hair growth drug minoxidil – a research study from back in 2015 showed it increased the hair count of alopecia sufferers after six months of use. And according to Dr. Zayn Majeed, hair surgeon at Harley Street Hair Clinic, studies have shown it to be effective at healing nerve endings and promoting hair restoration.
“Rosemary oil can strengthen circulation and improve blood supply to hair follicles, preventing them from being deprived of essential blood supply,” he explains. “If hair follicles don’t get a sufficient blood supply, this may shorten the growth phase of the hair growth cycle, and lead to hair loss over time.” Not only does it help you achieve longer hair, but it’s also beneficial for hair health overall. “Rosemary oil’s anti-inflammatory properties help to reduce scalp irritation, dandruff, and itching, providing a more optimal environment for healthy hair growth,” Dr. Majeed adds. Alongside its circulation-boosting and antimicrobial properties, it’s a great ingredient for supercharged hair care.
But temper your expectations: while the cult oil can work miracles to increase hair growth, it’s not a cure for stopping hair loss completely. “There’s currently no clinical cure for hair loss, though it can be slowed with medications and treatments like hair transplants,” says Dr. Majeed.
How to use rosemary oil for hair growth
You’ll find all kinds of rosemary remedies online, from homegrown herb/oil infusions to spiking haircare with essential oil drops. But the best way to incorporate it into your routine? Apply diluted rosemary oil directly to the roots or bald patches and massage it into the scalp. Massage increases the oxygenation of hair follicles through increased blood flow, and according to Claire Martin (brand educator at bestselling brand Mielle Organics) a large supply of oxygen is crucial for hair to grow at its full potential.
