Schwarzkopf Professional BlondMe Blonde Wonders Glaze Mist is a leave-in, anti-pollution topcoat for use on all hair types. Formulated with 3D Bond Creation Technology, it creates a protective layer which effectively seals the hair's surface, protecting it from external aggressors such as pollution, dust and hard water residue. A UV filter helps to protect the hair from damaging sunlight. Directions of use: Shake well before use, then spray evenly onto damp hair. Leave in.
