These 7 Rosemary Hair Oils Make Strands Grow ‘Like a Weed,’ Starting at $9

It’s been a surprisingly good year for my hair. There’s been less noticeable split ends, flaking, and even itchiness in my scalp. And despite applying heat to my strands constantly, I’ve also seen (along with family and friends) that it looks a lot stronger and fuller than before. Truthfully, I owe all my credit to hair growth treatments. Among my favorite ingredients, rosemary oil ranks top of my list for a natural solution. 

Even experts agree that this nourishing ingredient can be beneficial for improving hair loss. “Rosemary oil contains ursolic acid, which helps to increase circulation to the scalp and promote hair growth,” explained BosleyMD trichologist Gretchen Friese in a previous Shape article. “It is also thought to be beneficial to hair because it can reduce excess oil, soothe an itchy scalp, and make hair shiny and silky.” It’s also been found to increase hair growth similar to minoxidil, an FDA-approved active ingredient.

While research is still limited on rosemary oil’s effectiveness, there are plenty of easy and affordable options in the market to see for yourself. Not exactly sure where to start? I’ve compiled seven rosemary hair oils, starting at just $9, which Amazon shoppers swear by for strong, luscious locks. 

7 Rosemary Oils for Hair Growth From $9

Botanic Hearth Rosemary Hair Oil

More than 20,000 Amazon shoppers have bought the Botanic Hearth Rosemary Hair Oil in the last month, saying it leaves hair “noticeably thicker” and “soft and silky.” This lightweight formula nourishes strands to eliminate breakage, dandruff, and dryness to reveal a stronger and more luscious appearance. And it’s thanks to its rejuvenating ingredients, such as rosemary, biotin, jojoba oil, castor oil, and more, which are must-haves for a healthier mane. 

Difeel Rosemary and Mint Oil

The Difeel Rosemary and Mint Oil is a solid choice if you don’t want to spend a fortune on hair growth treatments. The now-$9 oil is made with strengthening ingredients, such as rosemary and biotin, to increase moisture, shine, and thickness in strands. It’s also infused with mint to stimulate blood circulation — similar to rosemary — in the scalp to encourage growth while providing a cool sensation to soothe an inflamed or itchy scalp. After using this formula, shoppers shared that their hair is “growing like a weed” and “shedding decreased significantly.” 

Mielle Organics Rosemary Mint Oil

The Mielle Organics Rosemary Mint Oil is the viral hair growth serum that has won the praises of more than 74,000 Amazon shoppers, including me. It’s one of my beauty staples thanks to its effective, plant-based formula that includes over 30 essential oils, such as rosemary, mint, and biotin to improve density, length, a dry scalp, and split ends. This treatment is truly a game-changer for the thinning spots around my hairline. Shoppers call this rosemary oil “magic” for growth, saying it leaves “a head full of three-inch hair” after three months. 

Handcraft Blend Castor Oil and Rosemary Oil

The Handcraft Blend Castor Oil and Rosemary Oil is budget-friendly and a best-seller for its rich blend of castor oil and rosemary oil. These extracts have moisturizing, antibacterial, and anti-fungal properties which are beneficial for a healthier scalp, as well as enable hair growth. This thick formula can also be used on eyelashes and eyebrows to create a fuller look, plus, it helps  alleviate dry skin.
