Yes, it is possible to give your hair a deep clean without sulfates — you just need one of the best sulfate-free clarifying shampoos featured here. Whatever your reason for avoiding sulfates — maybe you have a skin sensitivity, or you recently had a keratin treatment — you can rest assured knowing that all of these shampoos are completely sulfate-free. Picking the right one for you will mainly come down to more practical concerns, like your preferred texture, scent, and brand, as well as your hair type and budget.
Some of the shampoos on this list are gentle enough to be used everyday, while others are better suited for occasional use. How often you use a clarifying shampoo depends on your hair type and lifestyle — for example, people who swim in chlorinated pools or use a lot of hair product everyday may benefit from using them more frequently, but for most people, once a month or once every other week is probably plenty.
