  • Hair waving and straightening method
    Patent number: 4296764
    Abstract: A process for the waving or straightening of hair by treating with an alkaline bisulphite and or sulfite preparation followed by neutralizing with hydrogen peroxide is improved by using an aqueous neutralizing solution in which the hydrogen peroxide is present in a concentration of from 0.65 to 3.4% by weight and proportional to the concentration by weight of available sulfur dioxide in the waving/straightening solution used prior to neutralization. The process avoids certain disadvantages associated with the prior art.
