Curly hairstyles can be accomplished by getting a permanent, often called a perm. During this process, hair is wrapped around rods and then treated with a chemical, such as sodium thioglycolate. This chemical disrupts the disulfide bonds in the hair, which is composed of a protein called keratin. It then reforms disulfide bonds in different places, forcing the hair to be curly. At what level of structure in the keratin protein does sodium thioglycolate work?
