The treatment commonly used for permanent waving is ammonium thioglycolate. This chemical is specifically designed to break and reform the disulfide bonds in the hair, allowing it to be reshaped into waves or curls. When hair is subjected to this treatment, it becomes flexible and can be set in a desired style. After applying ammonium thioglycolate, the hair is usually neutralized to stop the chemical process and to ensure the new wave or curl pattern holds.

Ammonium thioglycolate is favored in the perming process due to its ability to create a wide range of textures and styles. Since it is a relatively mild reducing agent, it is suitable for most hair types, making it a versatile tool for hairstylists performing permanent waves.
