Mielle Organics Rosemary Mint Strengthening Shampoo is Amazon’s number one best-selling hair regrowth shampoo, and it’s available for $10. Shoppers swear by the hair growth product for thicker, longer locks and reduced hair shedding.

It’s a number one best-seller for a reason.

While you may have already stocked up on sandals, sunglasses, and handbags for the season ahead, there’s one more accessory that’ll complete your summer looks: a full, bouncy head of hair. Summer is the season of beach waves, but if you (like me) weren’t naturally blessed with thick locks, it’s time to revamp your hair care routine with new treatments. And, according to more than 13,000 Amazon shoppers who have rated it five stars, the $10 Mielle Organics Rosemary Mint Strengthening Shampoo is the one to get. 

The product has been purchased more than 40,000 times in the past month alone, per Amazon, earning it the title of number one best-selling hair regrowth shampoo. It’s packed with nourishing ingredients, including rosemary and mint essential oils to improve scalp circulation, coconut oil to moisturize and protect your hair, babassu seed oil for hydration and increase shine, and biotin to thicken your strands.

For the best results, the brand recommends using a dime-sized amount of the shampoo and massaging it into your wet hair until it creates a lather. Then rinse it out and continue with the best-selling Mielle Organics Rosemary Mint Strengthening Conditioner, which is also available for $10 at Amazon.

If you need more reasons to purchase the shampoo beyond its affordable price tag and all-star lineup of ingredients, look no further than its Amazon reviews section. One shopper said their “fine, thin hair was struggling to grow and looked absolutely dull, lifeless, and dead,” but after using the Mielle product for a month, they had “so much new growth, as well as the volume and texture [they] thought was lost for good.” Another reviewer called the shampoo a “game changer,” since it leaves their hair “feeling clean, soft, and revitalized.” 

The praise doesn’t stop there; a third shopper, who has been using the shampoo and conditioner for a month, said the products “added inches and thickness to [their] hair.” Plus, someone else “noticed less shedding” since using the shampoo, and their hair “has more body to it.”
