A shopper says their hair is "growing really thick" thanks to the formula.
If you follow beauty ingredient trends, you’ve undoubtedly noticed an influx in hair oils, serums, and shampoos spiked with rosemary extract. The herb—yes, the same one you’d sprinkle over crispy potatoes—supposedly spurs hair growth when applied topically to the scalp.
When rosemary oil for hair growth spurred a social media frenzy a year or so ago, I’d dismissed the concept as an iffy trend. Shopper acclaim for products like Amazon’s Hiqili Rosemary Oil, however—plus scientific evidence pointing to rosemary oil’s strand-strengthening benefits—have converted me on the issue. Considering rosemary oil for yourself? Same—and Hiqili’s is a mere $7 right now ahead of Amazon Prime Day.
Hiqili Rosemary Oil
Orig. $8 $7 at Amazon
The Hiqili Rosemary Oil is a pure essential oil, extracted via steam distillation from its titular ingredient. The liquid formula harnesses the herb’s purported powers, including faster hair growth, stronger, breakage-resistant strands, and amped up shine.
While these benefits may read like a list of over-promises, the science checks out. As dermatologist Dr. Marisa Garshick, M.D., previously told InStyle, rosemary may “improve circulation in the scalp.” This blood flow increase “may help stimulate hair growth,” she concluded. More impressive still: A 2023 study determined rosemary extract works as effectively as minoxidil—the active ingredient in over-the-counter hair loss products like Rogaine—citing “significant hair growth promoting activity” from a rosemary-infused solution.
To use Hiqili’s oil, simply apply a few drops to a clean, damp scalp and massage. Alternatively, the brand suggests adding the product to your regular shampoo and conditioner (a brilliant hack for anyone who struggles with consistency). Either way, the oil emits a spa-like herbaceous aroma, creates a refreshing scalp-feel, and, per shoppers, delivers on its hair-enhancing, growth-spurring claims.
One shopper reported their “hair is growing really thick,” while a separate reviewer reports “softer” strands that “grow so much faster.” Yet another reviewer reported rapid growth, going as far as to call the oil life-changing. Another fan loves using it on their scalp, where it provides a “cooling” effect that’s “relieving.”
For stronger, softer hair, rapid growth, and a tingly treat for your scalp, shop the $7 Hiqili Rosemary Oil at Amazon.
