A revolutionary pre-shampoo treatment that acts as a magnet to attract and then eliminate the damaging minerals and metals found in hard water you wash hair with, Color WOW Dream Filter Treatment removes the agents that can dull and roughen locks and cause colour to fade. Expect brighter and more radiant hair that feels fresher and lighter. Hard water contains remnants of iron, copper, calcium and magnesium that over time cause hair to become dry and brittle, fading colour and tinging lighter shades with brassy or orange tones. This ground-breaking but gentle treatment spray acts as a filter to these minerals and although effectively eliminates them from the hair, doesn’t strip or damage locks. Used for the first time in a hair care treatment, cutting edge technology amalgamates two molecular filters and two polymeric filters to draw in and then quickly remove minerals and metals so hair is left softer, cleaner and more uniform in colour and texture. Dream Filter works on all hair types and shades to detoxify and purify the hair. On lighter shades that are prone to discolouration, it effectively defends against brassy tones. Used as a pre-colour treatment shampoo, hair colour is distributed more evenly. Apply to dry hair before shampooing every 3-4 washes or more frequently if needed. Leave on for between 1-3 minutes before cleansing hair.
