According to University of Chicago Medicine, apple cider has proven blood-sugar-lowering benefits and can also reduce bacteria growth—a key for scalp care. If you ask the more than 7,000 five-star WOW Apple Cider Shampoo reviewers on Amazon, they'll claim the ingredient can also solve ailments ranging from psoriasis to itchy scalp to thinning hair, which may be why 17,000 bottles were purchased last Amazon Prime Day. Now fans can get their hands on a duo of WOW Skin Science hair products for 30% off, but you'll need to act fact because the offer is valid today only.

It's not only the apple cider benefits that have this shampoo and conditioner set flying out of the warehouse faster than you can say lather up. It's the brand's dynamic duo of Apple Cider Vinegar Shampoo paired with Virgin Coconut Oil Hair Conditioner. The two make quite the pair with purifying apple cider detoxing the scalp to promote healthy hair growth while the conditioner's virgin coconut and avocado oils restore nutrition for smooth, silky strands.

Both products are devoid of parabens, sulfates, and silicones, and are safe to use on color-treated hair. Based on information from reviewers, the trick is to follow the directions printed on the bottles, which includes letting the shampoo sit on hair for three to five minutes after lathering. Other reviewers warn that you'll need to give it a bit of time to work its magic—meaning you might not see results after the very first wash.

A couple weeks in, you could find yourself dropping five stars and a comment like one reviewer who wrote, "I NEVER do follow ups....I NEVER reorder shampoos online...well just reordered. This stuff is really amazing...not only can I now go 2-3 days without washing my hair, it doesn't look nasty in between washes."
