Sulfate-free shampoo is a must in the beauty world, which begs a couple questions...what are sulfates, and why should we care whether they're in our shampoo or not? Sulfates are harsh detergents, made of mineral salts, that you typically find in products like shampoo, facial cleanser, toothpaste, and body wash. And while they do dissolve dirt, grime, and product buildup, they also do some pretty harmful things, too: like stripping away all your natural oils and moisture. This can result in dry, damaged, brittle hair over time, as well as an itchy, inflamed scalp. Um, no, thanks. Here are the five best sulfate-free shampoos to try.
