TikTok’s Rosemary Oil Trend, Explained

As the never-ending quest for longer, thicker hair continues to thrive on social media, we’ve seen numerous solutions become popularized for hair loss. But none as notorious as rosemary oil, perhaps. Believed to offer several benefits for hair health, the potential effectiveness of rosemary oil for the prevention or reduction of hair loss is raved about worldwide, and especially on TikTok.

Rosemary oil is made from the aromatic herb rosemary, distilled from its leaves and flowers, and collected after steam is introduced to the plant. While there isn’t much to look at when it comes to scientific studies on how rosemary oil can assist in achieving better, bigger hair for longer, there are a few that point to its positive benefits—but much more research has to be done to assess these findings fully. Still, thousands of videos all over social media say otherwise, with creators screaming its praises.

Does rosemary oil actually help with hair growth?

Some studies like this one from the National Library of Medicine have shown that rosemary oil can help promote hair growth even when compared to traditional medicine like minoxidil, where both groups of participants “experienced a significant increase in hair count” over a period of six months. “As a highly inflammatory ingredient, rosemary oil is believed to improve circulation which can then promote cellular turnover and growth,” according to Shab Caspara. “It also is believed to have anti-inflammatory properties,” says Clariss Rubenstein.
