Rosemary hair oil has officially been dubbed the holy grail of hair growth and for good reason. Many girls with long, lustrous hair have been gatekeeping the secret of their lengths for way too long and we're all finally in on the secret.
It's no wonder that #rosemaryoil has amassed over 200million views on TikTok. Although this simple yet special concoction of rosemary sprigs and olive oil has been used for centuries to promote hair growth and improve hair quality, specially in the Mediterranean region, more recent studies have shown its exact effects and how they work.
A 2015 study comparing rosemary oil to minoxidil (a popular hair regrowth treatment) — where people with DHT-related hair loss used either rosemary oil or minoxidil twice a day for six months — showed that after six months both groups had seen significant increases in hair growth. However, the group that was treated with rosemary oil had more hair growth than the minoxidil group.
This result suggests that rosemary oil may promote hair growth but only in the long term. In the same study, scalp-itching was more common in the group that received minoxidil. This also suggested that rosemary oil could be a better option for people with a history of allergies or skin irritation.
The science is telling us that it works but as with anything there is a catch, rosemary oil needs to be applied in the right quantities, often enough and under specific conditions. Here is everything you need to know about implementing rosemary hair oil into your hair routine for your best-est and longest hair yet.
Does rosemary hair oil help hair grow?
“Rosemary oil has been scientifically proven to have positive effects on hair growth. Studies have demonstrated that rosemary oil can stimulate hair growth by improving blood circulation to the scalp and promoting the proliferation of hair follicle cells. Additionally, the oil has been found to possess anti-inflammatory and antioxidant properties, which can help to prevent hair loss and improve overall hair health. Its ability to increase cellular metabolism in hair follicles also contributes to its effectiveness as a hair growth stimulant.” says Dr Nick Fisherman, Trichologist at Watermans Hair.
