Clarifying shampoo, on the other hand, “has stronger surfactants (aka cleansers) that remove buildup, oils, and residue,” says Buechner. “It’s meant to be used as a treatment.” So don’t reach for your clarifying shampoo every wash the way you would with a regular cleanser.

When should you use clarifying shampoo?

Use clarifying shampoo “Once a week maximum to avoid dryness of the scalp and hair,” says Novobielski. Because the formulas are stronger, lather up less often with these: You want to promote hair health, not strip your scalp and hair of their natural oils by using them too often.

If we want to get more specific, how often you use a clarifying shampoo also depends on how you style your hair or how often you experience buildup, notes Buechner. “If you use heavier styling products like gels or hairspray, it is best to use a clarifying or detoxifying shampoo every four to five shampoos,” she advises.

Oily scalp friends: Consider switching to a sulfate shampoo for a more intense cleanse for daily washing, and then detoxify every six to eight shampoos with a clarifying shampoo, says Buechner. Essentially, you can’t go wrong as long as you’re detoxing your scalp with a clarifying formula whenever you’re feeling excessive buildup. “A clean and clear scalp leads to healthier hair growth,” Buechner says.

Who should not use clarifying shampoo?

Detox shampoo is strong, which makes it so effective at deep cleaning your strands and scalp. But it’s not for everyone. If you have a sensitive scalp, Buechner recommends steering clear as it may cause irritation. Dealing with dry or damaged hair? Clarifying shampoo could cause further dryness, so avoid these formulas if that sounds like you, says Novobielski. Oftentimes, this is the case with color-treated hair. Colored hair should also “use clarifying shampoo sparingly to avoid hair color fading,” adds Novobielski.

Lastly, curly girls: “Use sparingly because curly hair thrives on moisture and could cause more dryness,” says Novobielski.

Will clarifying shampoo dry out hair?

Yes, clarifying shampoo can absolutely dry out your hair, especially if you’re using it too often. However, there are simple ways to help avoid this and even give moisture back to your hair.

“After clarifying shampoo, use a deep conditioner, leave-in conditioner, or hair oil rich in lipids to restore moisture and prevent dryness,” says Buechner. Apply that hair mask or deep conditioner to your hair in the shower after washing, in place of your regular conditioner. Leave it on for about five minutes before rinsing. For even more hydration, apply a leave-in conditioner or hair oil on damp strands post-shower as well.
