In case you were wondering about the "two" in its name, Paul Mitchell actually has multiple clarifying shampoos. One of them focuses more on chlorine and mineral deposits, while this one removes oils and product buildup -- while still being safe for color-treated hair.

Clarifying shampoos have a tendency to dry out hair if overused -- which is what makes Moroccanoil's take on the product so exciting. Since it's made with lots of moisturizing argan and avocado oils, as well as strengthening keratin, this shampoo won't leave your hair feeling too stripped or (the horror!) straw-like.

Specially formulated for curly hair, this clarifying shampoo doesn't mess around. Though it's made with natural ingredients (it's sulfate free!), it really gets everything out of your strands, so be sure to follow up with a nice conditioner. Oh, and another bonus? The adorable packaging and the deliciously aromatic mandarin orange extract.

You can kill two birds with one stone with this popular shampoo -- it clarifies and adds volume. It uses 2.3% peppermint oil, as well as 16 other plant extracts to get the job done, busting oil and product residue for lighter and bouncier hair. Oh, and thanks to the aforementioned peppermint oil? It makes your scalp tingle, which stimulates circulation (plus, it feels really good).

So-called because it's meant to be used once a week to prevent "shampoo boredom," Bumble and Bumble's Sunday Shampoo is considered one of the best clarifying shampoo treatments. In addition to removing product buildup and oil, it also helps get rid of environmental pollutants and mineral deposits, which is great if you live in an urban area with hard water. Taking a break from your usual shampoo routine and using this bad boy once a week also promotes detoxification in your scalp, as well as adding some welcome vibrancy to your mane.
