Final answer:
The correct option for rearranging overly curly hair into a straightened form is A) Relaxer treatment. This involves the chemical process of breaking and re-forming disulfide bonds in the hair to alter its texture from curly to straight.
Step-by-step explanation:
The process used to rearrange overly curly hair into a straightened hair form is commonly referred to as a relaxer treatment. This chemical process changes the structure of the hair by breaking down the disulfide bonds that link the protein chains within the hair, which are responsible for hair's strength and curl. By applying a reducing agent, the curly structure of the hair's alpha-helices is relaxed, and an oxidizing agent, typically hydrogen peroxide, is used afterwards to neutralize the process and set the hair in its new, straightened form.
While perms and texturizing treatments also involve the disruption and reformation of disulfide bonds, they are used to create curls or waves rather than straightening the hair. Keratin treatments, another popular hair straightening option, involve coating the hair with a protein layer to smooth out its texture. However, when looking to directly rearrange overly curly hair into a straightened form, a relaxer treatment is the specialized process designed for this purpose.
