There are a lot of ingredients touted by TikTok tweens and unaccredited Instagram talking heads. Many are just snake oil but you know which isn’t? Rosemary. It’s prolific in hair care, sometimes being the titular ingredient and other times hidden in the formula; it’s in everything from shampoos to serums to masks. One of the most popular methods of reaping its benefits is through a hair oil—and if you’re looking for one, this one from Majestic Pure is just $15.

This is a no-frills, big bottle of rosemary oil that comes with two changeable heads. One is a typical nozzle and the other is a genius little comb that disperses the oil—something I wish all hair oils came with.

The formula is heavy on rosemary, which studies have found is as effective at promoting growth as minoxidil (Rogaine). But the herb doesn’t work alone; there’s also biotin, plus castor and jojoba oils. While there’s not much evidence supporting the hype around biotin and what it can do for your hair, jojoba oil is similar to the oils your scalp naturally makes, so the ingredient easily penetrates the hair shaft to deliver hydration, strength, and protection. Castor oil improves the overall scalp health and kills the germs and infections that slow hair growth.

Of the many positive reviews, a hairstylist said that the formula is growing out their dyed-platinum hair “gorgeous and thick.” Another person who had “two spots where hair wouldn’t grow” said the $15 oil actually grew it back. A third reviewer said this treatment makes their hair “feel like velvet” and grow “inches.” Majestic Pure’s Rosemary Oil is great for spots other than your scalp; “it grows lashes, brows, nails, and hair, ”per a reviewer. Several others claim that it’s great for softening skin, too.

Head to Amazon to shop Majestic Pure’s Rosemary Hair Oil—at $15 it’s already affordable, so I’m not that miffed that it’s not discounted for Prime Day. That being said, check out some top Amazon Prime Day hair growth deals below.
