Dry/damaged hair: For those with dry or damaged hair (or both), a clarifying shampoo may strip away oils because of harsh cleansers like sulfates, which can weaken hair and may worsen dryness, according to certified trichologist Afsennah Kalanawi. Consider a shampoo that is sulfate-free to prevent more damage, says Rose. Also, choose a shampoo that has moisturizing ingredients like glycerin to prevent excessive dryness, says Kalanawi. Jen Atkin, queen of dry shampoos and style maintenance products, knows the importance of cleansing the hair of buildup, and this product proves it—just ask the thousands of happy customers who’ve made it go viral on social media. Several reviewers comment on how helpful this formula is with combatting bleach damage and highlight-destroying buildup, while another calls this shampoo "the perfect 'reset' when you use the product throughout the week.” Plus, its apple cider vinegar-infused formula supports strong, shiny strands from top to bottom. While it may seem spenny for a shampoo, this formula is worth every penny for its smart technology in safely removing damaging impurities from the surface of the hair; that is, without stripping or drying.

Gentle cleansers: Many clarifying shampoos are formulated with sodium lauryl sulfate (SLS), a foaming agent that deep cleans to remove flakes, excess product and dirt from your hair. However, the ingredients can be very drying. We avoided it when possible and chose options with gentle cleansers, including apple cider vinegar, which helps maintain scalp health, says certified trichologist Shab Caspara.

It aims to restore the natural pH balance of your scalp to help curb the need to itch.That being said, it's not exactly the best idea to deep-clean your hair with a clarifying shampoo every time you wash it (since clarifying shampoos have harsher ingredients, which, if used too regularly can dry hair and scalps out), a once-over every so often deep-cleanse could just be the answer to peak hair health.

Why we love it: This weightless yet deeply nourishing formula contains white vinegar and scents of rosemary and peppermint. Ideal for washing away dirt, excess oil and product build-up without eliminating moisture.As you might have guessed from the name, this formula contains nutrient-rich thermal mud, which essentially acts like a mud bath for greasy scalps. If you’re struggling with frizz as a result of hard water, pollution, and product buildup, consider this shampoo from Virtue. It contains a number of healing ingredients like coconut fatty acids, hops extract, and charcoal powder, but its allstar component is alpha Keratin 60ku, a healing protein identical to the keratin that makes up 90 percent of human hair. Thus, the influx of protein that this shampoo provides restores damaged strands with every use. One promising review reads, "My hair didn’t feel dried out or straw-like, like with most purifying shampoos."
