    Patent number: 5565192
    Abstract: A process for permanently reshaping hair consists of applying an amino compound, an amidothiol compound or a salt of an amino compound or an amidothiol compound as a reducing agent to open the keratin bonds of hair and reforming the bonds using an oxidizing composition or aerial oxygen, wherein prior to or simultaneously with the application of the reducing agent, at least one alkali metal, alkaline-earth metal or ammonium bromide is applied to the hair as a doping agent for the reducing agent. A composition for carrying out the process contains at least one amino compound, amidothiol compound or a salt of an amino compound or an amidothiol compound as a reducing agent, at least one alkali metal, alkaline-earth metal or ammonium bromide as a doping agent for the reducing agent, and a suitable cosmetic vehicle.
