No, this is not a "clarifying shampoo," however, many of our customers use this set to clarify (cleanse their hair from build-up) in between using our CoWash Cleansing Conditioner, to remove build-up regularly. Just to clarify ... Clarifying is doing a more intense wash than usual, to remove build-up, such as build-up from products, oil production from your scalp or hard water. You can clarify in different ways, and it really depends on how deeply you are needing to cleanse, that determines if you actually need a clarifying shampoo. As you may know, using a clarifying shampoo on colored, keratin or chemically treated hair too often can cause your hair color or your treatment to fade faster. Therefore, for most, it's best to clarify with a gentle sulfate-free shampoo regularly (1-3 times per week, depending on your hair type), or use a designated clarifying shampoo no more than once a month. You absolutely do not want to clarify your hair with a clarifying shampoo within the first few weeks of a fresh color or treatment. In fact, some stylists advise not using a clarifying shampoo at all with certain treatments, as it can damage them.
