Final answer:
The process to chemically restructure straight hair into a different wave pattern is the Perm treatment, which chemically alters the hair's disulfide bonds using a reducing agent, shaping the hair around forms, and then reforming the bonds with an oxidizing agent for a lasting change.option b is correct.
Step-by-step explanation:
The correct option for the chemical process used to change the wave pattern of straight hair is B) Perm treatment. Perming involves using a chemical solution that breaks down the hair's strong disulfide bonds. These bonds are present between the protein chains in the hair and contribute to its natural shape.
During the permanent wave process, a reducing agent, typically ammonium thioglycolate, is applied to the hair to reduce and break these disulfide bonds. Afterward, the hair is wrapped around forms, such as rollers, to reshape it. Then an oxidizing agent, usually hydrogen peroxide, is used to reform the disulfide bonds in their new shape, resulting in a permanent alteration of the hair's natural wave pattern.
