Pureology shampoo has a unique formulation that boosts hydration in your hair, repairing dead skin cells on your scalp. This helps prevent dandruff and dry, itchy scalp. It also contains aloe vera, which helps regulate sebum production in the scalp to prevent clogged pores. Unlike other shampoos, Pureology contains zero synthetic fragrances and zero sulfates. It also helps protect hair coloring from the harsh chemicals used in other shampoos.

The tingle in Pureology shampoo is the result of menthol, an ingredient added to shampoos for its cooling properties. Menthol can come in different forms, but it is usually added to other ingredients like peppermint, mint, and eucalyptus oil.
