A significant number of consumers use products to curl or straighten their hair. These products function by chemically breaking and reforming keratin disulfide bonds. The most popular waving products contain salts of thioglycolic acid to break the bonds and hydrogen peroxide to reform them. Straighteners generally rely on high alkalinity to break the bonds and reform them with acid. Problems with permanent waving are usually due to overtreatment or undertreatment of the hair rather than allergy or irritation. Straighteners can be irritating because of their high alkalinity and can seriously damage hair if used excessively.
相当多的消费者使用产品来卷曲或拉直头发。这些产品通过化学方式破坏并重新形成角蛋白二硫键来发挥作用。最流行的烫发产品含有巯基乙酸盐来破坏键，并用过氧化氢来重新形成键。直发器通常依靠高碱度来破坏键，并用酸来重新形成键。烫发的问题通常是由于对头发过度处理或处理不足，而不是过敏或刺激。直发器因其高碱度可能会有刺激性，如果过度使用会严重损害头发。
