With professional-use-only products, you can provide your clients certain services that are not readily available to them at home. Some of these products are designed to be freshly prepared for them during treatment to optimize results. Often, they are specially priced for professional use despite being more concentrated in active ingredients. Others must be performed by qualified professionals for safety reasons, enabling them to continuously monitor their clients during treatment. Certain products serve as diagnostic tools to help the professional to select the home care products they should recommend to their clients.
