Amazon Shoppers Went Crazy Over This Apple Cider Vinegar Shampoo—And Bought 17,000 Bottles on Prime Day

Apple cider vinegar shampoo can do it all from relieving itchy scalps to restoring thinning, damaged hair.

While apple cider vinegar has long been a pantry staple and cleaning power player, more recently it’s become a trendy beauty and hair care ingredient used to treat acne, eczema, and dry, flaky skin. Case in point—this now insanely popular shampoo and conditioner set that’s blowing up on Amazon.

Wow Skin Science’s apple cider vinegar shampoo has reached the top of Amazon���s best-sellers chart in its enormous beauty and hair care departments, and is now driving an impressive $1.4 million sales per month, the brand told RealSimple.com. What’s more, over 17,000 bottles were sold during Amazon’s 48-hour Prime Day shopping event this year. The under-$20 cleanser is designed to treat hair loss, frizz, dandruff, damage from coloring, oily scalps, and product buildup. Amazon shoppers also love its volumizing formula and subtle scent.

To buy: $19; amazon.com.

Since apple cider vinegar is naturally antifungal and antibacterial, it’s a great way to treat a dry scalp and dandruff while removing residue from other hair products. In fact, apple cider vinegar can be used on its own to add shine and volume to your hair, though this shampoo’s added almond and argan oil will help your hair feel even softer and look shinier.

The hypoallergenic cleanser is designed to be used about twice a week, so one bottle will last you a while, and it can be used by all hair types. In fact, Amazon shoppers with all kinds of hair—curly and straight, as well as those with dry and oily scalps—all rave about the sulfate- and paraben-free shampoo.

“At first I was very hesitant to spend $20 on a bottle of shampoo, but I had tried everything else I could think of and my scalp was still flaking, itching, and my hair would get oily very quickly,” one reviewer shared. “I use this shampoo three times a week, and the results have been great. It has brought my curls back to life, and I will definitely be buying another bottle once this one runs out.”

“This is by far the best shampoo I've ever used,” another chimed in. “I noticed immediately after the first use of this shampoo, no itching, flaking, or irritation. That, in itself, won me over. It also has the best subtle smelling fragrance.”

Those with limp strands have also seen a difference after using the cleanser. “I love this shampoo,” another reviewer wrote. “It doesn't weigh my fine hair down. And I have super sensitive skin and this doesn't irritate it. All of the eczema on my neck and scalp cleared up. I am so glad I bought this!”

The brand also makes an apple cider vinegar foaming face wash and facial toner to round out your skincare routine, further proving the ingredient’s versatility. Better stock your pantry while you’re at it—we have a feeling you’ll be reaching for it on the reg.
