One way you see this in the hair care space is with bars. This is great because switching to bars means less packaging—no plastic tubes, tricky pumps, or so on: These handy little self-contained beauty products come wrapped in paper. And with more options come more diverse offerings, better able to tend to all hair types—from straight to curly, from color-treated to sensitive scalps. Here, our favorites. In shampoo bars, for example, you’ll find natural surfactants and cleansing agents. In conditioner bars, like the below, you’ll find loads of nutrients and hydrators. When using a conditioner bar, you can do it one of two ways: Apply it directly to your hair, letting the strands soak up the nutrients, or work it between your hands first before transferring the product. Just be sure you’re using enough—it may take time to get used to how much you need—but one sign that you’re not applying enough is if you are having trouble detangling or your hair feels knotty.
