If you’ve researched remedies for thinning and shedding, you’ve likely heard people swear by rosemary oil for hair growth. Doubly so if you peruse beauty-centric posts on TikTok, where people are particularly abuzz about the rosemary oil from Nature Spell. Hailing from a London-based brand, which claims it among the top-selling rosemary hair growth oils in the United Kingdom. Case in point: More than one million people have purchased the product.

As a stateside-dweller, I’m just catching wind of the thickening treatment. Luckily, though, I needn’t hop across the pond to snag my own bottle: The famous oil is available at Amazon for a mere $10.

The Nature Spell Rosemary Oil

The Nature Spell Rosemary Oil is a topical treatment composed of its titular ingredient, among other plant extracts known to spur new growth and strengthen existing strands. Simply put, rosemary boosts scalp circulation, which transports nutrients to hair follicles. Ultimately, “this blood flow may help stimulate hair growth,” dermatologist Dr. Marisa Garshick, M.D., previously told InStyle. Studies corroborate this theory: One even found the herb on par with minoxidil (a non-prescription, FDA-approved hair loss drug).

In addition to its star ingredient, Nature Spell’s treatment contains sweet almond oil. Rich in vitamin E, the lightweight oil protects and conditions the scalp—and, inadvertently, maximizes growth potential. (Hair follicles require a healthy scalp environment to thrive, after all.)

Better yet, the oil is a breeze to use. Simply massage a few drops directly onto your scalp two or three times per week. Style your hair as usual or shampoo anywhere from 30 minutes to four hours post-application.

This relatively low-commitment regimen yields impactful results, per shoppers. One reviewer said their hair is “getting thicker” thanks to the $10 rosemary hair oil, while another person attributed newfound strand smoothness to the formula. A final fan, who experienced “hairlessness” as a Covid-19 side effect, achieved “regrowth” from the oil, which their stylist recommended.
