Why Using a Clarifying Shampoo Is Key for Thick, Healthy Hair, Plus the Best Ones To Use

Experts share how often you should be using one of these deep-cleaning formulas


Do you ever feel like your hair isn’t really clean, even after you’ve washed it? Maybe you still feel waxy product on your strands or extra oil on your scalp. You’re not crazy — sometimes our regular shampoo just doesn’t cut it, especially if we go days between washes or have been sweating a bit more than usual (hello, summer). Enter: Clarifying shampoo. These build-up removers, scalp-loving suds work overtime to deliver truly clean, residue-free hair. Here, how they work, who should use them and the best clarifying shampoos on the market, backed by top hairstylists.

What is clarifying shampoo?

Clarifying shampoo is essentially a more intense version of your regular shampoo. It’s designed to target the scalp, making it extra clean and free of product build up, sweat and dirt. “Clarifying shampoo is strong shampoo that removes buildup in order to detox and refresh your scalp,” says Rae Ann Cotto, Colorist at NYC THE TEAM Hair Salon. “It’s meant to cleanse dirt and oils due to a range of things from sweat from a workout to one too many days between regular shampoo time.”

When we have build up on the scalp, the rest of our hair can greatly suffer. Oils, product and sweat can clog the hair follicles, which can lead to hair loss, dandruff and an array of other problems. A happy scalp equals happy hair, so it’s important to treat it with a little extra TLC.

Overall, most people can benefit from using a clarifying shampoo, says Cotto. “I recommend all of my clients to use a clarifying shampoo 1-2 times per month.” However, you may need increase that number or not use at all, in certain cases: “If you are someone who works out more than four days a week, then I suggest every other week,” she notes. Or if you have a keratin treatment “then you only want to use it when you’re going to the salon to refresh your keratin.” And if you’re dealing with thinning hair, a clarifying shampoo deeply cleanses the scalp, removing product buildup, dead skin cells, dirt, oil and other impurities that can clog hair follicles and stall hair growth. So clearing the pathway keeps follicles healthy to promote growth.

Further, clarifying shampoos typically work on most hair types, but those with a more oily-prone scalp can benefit even more from using one. Cotto compares it to skincare: Just like there are certain cleansers for normal to oily skin, there are different shampoos oily scalps should be using. “Clarifying shampoos work the best on fine-, medium- or heavy-density hair and normal to semi-oily scalp (think normal to combination skin),” she explains.

A word of caution, however, according to Cotto: “Be very careful to not overuse the clarifying shampoo! Overusing the shampoo can dry out your scalp and cause your body to produce more oil…. even for my oily scalp clients, this can make your situation worse! The irony is you should be using an oil shampoo instead of clarifying to detox your scalp.” That’s why it’s recommended to use a clarifying shampoo no more than once a week or once every other week.
