Clarifying shampoo basics
A clarifying shampoo is typically used to lift product residue, oil and mineral deposits from hair and scalp. It uses surfactants, which are cleansing agents that help lift these materials so they rinse away. Wet your hair, work the product into the scalp and lengths, then rinse well. Check the label for how often the brand suggests using it. Results vary by hair type and routine.
