What type of shampoo is specifically designed to remove product buildup?

The correct choice is clarifying shampoo, which is formulated specifically to remove product buildup from hair and scalp. Over time, the accumulation of styling products, oils, and other residues can lead to a dull appearance and weigh the hair down, making it look lifeless. Clarifying shampoos contain stronger detergents compared to regular shampoos, enabling them to effectively cleanse the hair and scalp, restoring freshness and vibrancy.

Moisturizing shampoos, on the other hand, are designed to hydrate and nourish dry or damaged hair, not necessarily to remove buildup. Color-protecting shampoos are intended for color-treated hair to help maintain vibrancy and protect against fading, which does not address buildup concerns directly. Volumizing shampoos aim to add body and thickness to fine or limp hair but do not specifically combat product residue.
