How often should clarifying shampoos be used for optimal results?

Clarifying shampoos are specifically formulated to remove buildup of styling products, pollutants, and minerals from hard water. Using them once a week strikes a balance between effectively cleansing the hair and maintaining its natural oils and moisture levels. Frequent use, such as every day or every other day, could strip the hair of its natural oils, leading to dryness and potential damage. Using a clarifying shampoo once a month may not be frequent enough for individuals who use many styling products or live in areas with hard water, meaning they might not achieve optimal results. Therefore, a weekly application is generally recommended to keep hair clean without causing undue harm.
