Glosses and glazes. These terms are used interchangeably today. Depending on the ingredients, they can either go into the cuticle of the hair or adhere to the outside of the hair. Glazes can be tinted to add color. Many of these products are not so different than products used to make car seats and dashboards shiny; they contain the polysiloxane family of silicone products. If your hair is glossed or glazed, it may prevent Hairprint from working as they are not designed to be removed by a clarifying shampoo. Please discontinue use for several days before applying Hairprint.
