The process of straightening curly hair using chemical relaxers involves breaking down the hair's protein structure. This method specifically targets the bonds within the hair strands that contribute to its natural curliness. When a chemical relaxer is applied, it alters the disulfide bonds, which are responsible for the hair's texture. By breaking these bonds, the hair is able to become more straight and manageable.

While keratin treatments can also straighten hair by applying a protein coating, they do not chemically alter the hair's internal structure in the same way that relaxers do. Perm solutions are used for creating curls, not straightening them, and hot oil treatments primarily focus on moisturizing and conditioning the hair rather than altering its structure. Thus, the process that directly transforms curly hair into a straighter form is indeed the one that employs chemical relaxers to modify the protein structure of the hair.
