Question

Quizplus · Accepted Answer

Permanently curled hair is achieved through a chemical process called a permanent wave. This process involves breaking down the disulfide bonds in the hair using a mild reducing agent, such as thioglycolic acid. Once the disulfide bonds are broken, the hair is wrapped around curling rods and a neutralizer containing a mild oxidizing agent, such as hydrogen peroxide, is applied to reform the disulfide linkages into their new curled shape. Therefore, the best choice is D, mild reducing agent; mild oxidizing agent.
