When your hair feels heavy or lifeless, try a clarifying shampoo. It can remove excess buildup, and give a deeper clean than regular shampoo. However, it’s not designed for everyday use — otherwise, it could dry out your hair or fade color, according to experts, who say once per week is more ideal.
We spoke to hairstylists, trichologists and dermatologists about what to consider when shopping for a clarifying shampoo and how to determine which one is best for your hair type. We also compiled expert-recommended and highly rated options to consider using.

Proceed with caution when using a clarifying shampoo since their cleansing ingredients are stronger than those in your standard shampoo. That being said, we kept the following in mind:
- Gentle cleansers: Many clarifying shampoos are formulated with sodium lauryl sulfate (SLS), a deep-clean foaming agent that can also be drying. Avoid it when possible and choose options with gentle cleansers, like apple cider vinegar, which help maintain scalp health, says certified trichologist Shab Caspara.
- Color-safe options: Sulfates and certain shampoos can strip color-treated hair, so look for options labeled color-safe and sulfate-free if you have a dye job, says board-certified dermatologist Dr. Jessie Cheung.
- Hydrating ingredients: To counteract the drying nature of clarifying shampoos, use one that also has hydrating ingredients like argan oil and glycerin.
Below is a list of expert-recommended and highly rated clarifying shampoos to consider. All of them are sulfate-free and made with gentle cleansers.

selectShould you consider switching to a shampoo bar? We asked experts
When shopping for a clarifying shampoo, our experts recommend considering your hair type, overall scalp health and ingredients that address your specific hair concerns and needs.
IngredientsConsider a clarifying shampoo that can remove buildup with gentle ingredients, according to our experts. For example, Caspara says apple cider vinegar can help reset your scalp’s pH level, and sodium cocoyl isethionate, a derivative of coconut oil, can clean without causing irritation. Another gentle cleanser that removes oil and buildup is,
It should also have moisturizing ingredients to prevent dryness — glycerin, argan oil, jojoba oil, aloe vera, honey and shea butter are just a few, according to our experts.
Avoid ingredients like formaldehyde, parabens, phthalates and sulfates, which can damage your hair, according to our experts. Formaldehyde can sometimes act as a preservative in clarifying shampoos but is a known carcinogen, says Rose. Parabens and phthalates can also cause future health problems since the body is able to absorb these preservatives, according to Rose. Depending on your hair or scalp type, sulfates can strip hair of natural oils and be irritating to the scalp since they are intense detergents, according to our experts.
Hair typeAll hair types can benefit from clarifying shampoo, but there are specific ingredients that work best for each one, according to our experts.
- 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 one that is sulfate-free and made with moisturizing ingredients, like glycerin, to prevent excess damage and dryness, say Rose and Kalanawi.
- Fine hair: Consider a lightweight formula made without heavy oils or butters that are harder to wash out, like coconut oil or castor oil. Argan oil and jojoba oil are better options.
- Oily hair: A standard clarifying shampoo can help remove any excess oil, according to our experts. Although many experts recommend staying away from sulfates as much as possible, they may not be as bad for people with oily hair, according to Rose.
- Keratin-treated hair: Be cautious of using a clarifying shampoo since it can diminish the longevity of the treatment, says Kalanawi.
If you have a pre-existing scalp condition like psoriasis or experience dandruff, you should avoid using a clarifying shampoo because it can aggravate these conditions, according to Rose.
Frequently asked questions
Clarifying shampoos can be beneficial for everyone, says Kalanawi. They’re especially helpful if you exercise frequently, use a lot of hair styling products or don’t shampoo your hair often, according to hairstylist Courtney Foster . However, how often or which type of clarifying shampoo will vary from person to person, depending on their hair texture and scalp health.
Yes, a majority of deep-cleaning agents in clarifying shampoos will fade out hair color. This only applies to color-treated hair, so it will not affect your natural color, says Kalanawi. If you are concerned about clarifying shampoos stripping your hair color, use a sulfate-free option, says Rose.
Limit use to once a week, says Kalanawi. However, there is no one-size-fits-all rule: your wash schedule should depend on how much you struggle with oil buildup and excess product residue.
Start small with the expectation that you will see visible results after a handful of washes, according to our experts. For example, swimmers who are regularly in chlorinated water may want to use a clarifying shampoo about once a week to help remove chlorine from their hair, says Cheung. Others simply looking for more bounce and less weight should assess the state of their hair after a couple of washes. After that, you can use your best judgment and incorporate a clarifying shampoo as needed, according to Cheung. Use a conditioner or hair mask to keep your strands hydrated after a deep cleanse, she says.
You can absolutely overuse a clarifying shampoo. If you use it too frequently, you are actually stripping your hair of its natural oils , which will make it feel dry and cause breakage, says Kalanawi.
Not only does overusing a clarifying shampoo affect your hair strands, but it also affects your scalp. You can cause your scalp to become dry, disrupt its microbiome and cause your hair to become brittle as a result, according to Caspara.
