Each week, we’re bringing you a bonus episode from Allure: The Science of Beauty, a new show answering the tough questions about skincare, hair, and more. In this episode, we're talking about shampoo.

Imagine a world where instead of using shampoo, you relied on the powders and liquids in your pantry to keep your hair looking (and smelling) fresh. That was reality just a little more than 100 years ago; Today, the shampoo aisle has a dizzying number of options. In this episode — our first to focus on hair — Michelle and Jenny try an old-school hair-washing method before cosmetic chemist and longtime Allure collaborator Ni'Kita Wilson joins in to share the latest and greatest ways to remove dirt, oil, and product build-up. And before you ask: Dry shampoo is not a replacement for the real stuff.
