Plus, where to buy the buzzy product.
Using rosemary oil for hair growth might not be the first thing that comes to mind when you think of the versatile herb. From cooking to aromatherapy, this age-old plant has many capabilities — and they extend into the beauty industry. Like finding the best hair masks and best hair oils, selecting the right rosemary remedy may transform your tresses.
How does rosemary oil for hair growth work?
Rosemary oil for hair growth is not a proven fix-all product, but some evidence has found it successful. “Studies show that rosemary oil can help micro-capillary perfusion, meaning it can support blood flow in the tiny capillaries where it’s applied,” explains Geeta Yadav, a board-certified dermatologist and founder of Facet Dermatology in Toronto.
In other words, increasing the blood flow to your hair follicles can support healthier growth.
Rosemary oil also has an antioxidant characteristic that may protect hair from environmental aggressors, such as UV radiation and pollution. “Rosemary oil comes from the Rosmarinus officinalis plant, with potential antioxidant and anti-inflammatory effects,” explains Monica Li, a Vancouver-based double board-certified dermatologist.
These anti-inflammatory components can help to foster a healthy scalp for hair growth (and keep symptoms like itchy scalp at bay).
Who can use rosemary oil?
This ingredient can be used on all hair types, whether your locks are thick or thin; colour-treated or natural. However, if you have sensitive skin, it might cause irritation, Li and Yadav warn.
To avoid a sore scalp, they advise patch testing a small area — like the wrist or behind the ears — before using it on your head. After two to three days of use, you’ll see if your skin tolerates it.
“There is no scientific data on the safety of rosemary oil on those who are pregnant or breastfeeding,” Li adds, noting that these individuals should avoid it.
