The Best Hair Oil We Tested Strengthens Strands and Smooths Split Ends — and It’s Only $9 at Amazon

If you’ve suffered from hair loss, you may have tried over-the-counter treatments to help accelerate growth. But if you’re looking for alternatives, there are a slew of treatments powered by natural ingredients. 

One in particular is the Mielle Organics Rosemary Mint Hair Strengthening Oil, and it’s currently just $9 at Amazon. The best-selling oil is packed with nutrients, including rosemary and mint, that work in tandem to nourish and strengthen your hair. Featuring 30 essential oils, the rosemary oil combats dandruff and lengthens hair. It can even be used to smooth split ends, giving you a shiny finish to your hair. 

This biotin-infused rosemary oil is safe for all hair types, including chemically treated hair, braids, and weaves. It can be used every day — just work a couple of drops of the oil directly into your scalp, combing it through your strands to the ends.

Over 100,000 Amazon shoppers have purchased the rosemary oil in the past month, and it’s picked up 58,000 perfect ratings. One five-star shopper wrote, “Trust me when I say my hair is growing in places I didn’t know it would,” while another added, “My hair and scalp have never been healthier.”  

A third five-star reviewer explained, “This product has truly transformed my haircare routine.” They continued, writing, “After using this oil for a few weeks, I’ve noticed a significant improvement in the overall health and strength of my hair. My strands feel smoother, softer, and more manageable, and I’ve even noticed less breakage and shedding.”

Amazon shoppers are hardly the only ones who have become obsessed with this product. We crowned it the best hair growth oil since it’s ideal for users who want to promote hair growth without having to rely on expensive serums. We also liked that the formula is potent in biotin and rosemary, which “is said to balance and regulate scalp health,” according to celebrity hairstylist Davey Matthew.
