There are so many shampoos on drugstore shelves that it can be hard to figure out which to choose. Some are sulfate-free, some feature keratin, others rely on tea tree oil or goji berries. Many advertise salon quality for less. But do they live up to their promises to make hair shinier, silkier, and more manageable? We tried eight drugstore shampoos on thick, normal to oily, color-treated hair with a slight wave, using each one daily for three days. We paired all the shampoos with the same conditioner and abstained from using conditioner on one of the three days to see the effects. Here are the contenders, starting with the cheapest (by price per ounce) and culminating in our pick for best drugstore shampoo.
