  • Patent number: 6506373
    Abstract: The oxidative hair treatment composition is made by mixing several components immediately prior to application on the hair. One component contains dehydroascorbic acid, its derivatives or salts or their mixture, is anhydrous or contains up to 10% by weight of water, and is a powder, granulate or tablet or micro-encapsulated or a suspension and another component is an aqueous, alcoholic or aqueous alcoholic preparation. In order to avoid an unpleasant mercaptan odor and provide a uniform treatment the method for permanently waving hair includes putting the hair into the desired form, treating it with a keratin-reducing agent, and then rinsing it, after which it is treated oxidatively with the above-described oxidative treatment composition and rinsed once again.
