Just like the rest of your skin, your scalp may lose moisture when the air gets dry, leading to itching, flaking, and irritation. One solid solution? The Wow Apple Cider Vinegar Shampoo and Conditioner Set. If you're wondering why you should put a household condiment in your hair, it turns out that apple cider vinegar can lower your pH, leaving your hair smooth, strong, and shiny. It's also antimicrobial and full of vitamins C and B, which means it may control the bacteria that lead to scalp and hair problems and help reduce dandruff. The "life-changing" Wow Apple Cider Vinegar Shampoo and Conditioner Set, as one customer put it, has been a best-seller for two and a half years, the brand tells InStyle, adding that 80,000 bottles once sold in a single day on Amazon. It has nearly 30,000 five-star ratings, so it's clear that the vegan, paraben- and sulfate-free, and color-safe shampoo and conditioner provide real results. Courtesy Shop now: $30 (Originally $35); amazon.com "My scalp was so itchy and covered in dandruff, [and] my hair was dry and brittle," one reviewer wrote. "The hair fall in the shower and brushing was bringing me to tears. I'm talking about hundreds of hairs. I've washed twice now, the first time my scalp felt amazing! It feels moisturized and soothed, and NO dandruff. Almost no hair came out in the shower or brushing. Thank you for turning my sad tears into happy ones!" In addition to apple cider vinegar, the product formulas contain coconut and avocado oils to rejuvenate damaged hair and dry scalps. Plus, the vinegar itself safely strips hair of built-up dirt and styling products, leaving you with your cleanest head of hair ever. The brand adds that this shampoo is completely safe to use every time you wash your hair, whether that's once a day or a couple times a week. Just make sure to shop the apple cider vinegar shampoo and conditioner set from Amazon while it's still on sale.
