How can barbers effectively remove product buildup from hair?

Using clarifying shampoos is the most effective method for barbers to remove product buildup from hair. Clarifying shampoos are specifically formulated to deeply cleanse the hair and scalp by stripping away residues left by styling products, oils, and environmental pollutants. Their stronger surfactants are designed to cut through heavy buildup that regular shampoos may not effectively eliminate.

While moisturizing conditioners, regular shampoos, and hair masks serve valuable purposes—such as hydrating, washing hair under normal circumstances, or providing additional nourishment—they are not specifically designed to address issues of product buildup. Regular shampoos might clean the hair, but they do so with milder agents that may leave some residue behind, failing to remove stubborn buildup. Similarly, moisturizing conditioners and hair masks are meant to enhance the health and shine of the hair rather than to cleanse it.
