Chemical hair straightening methods primarily involve the use of specific products that alter the structure of the hair to achieve a straighter appearance. Relaxers and keratin treatments are both common chemical processes used for this purpose.

Relaxers work by breaking down the disulfide bonds in hair, which allows for a permanent straightening effect. These products come in different forms, including lye-based and no-lye formulations, catering to various hair types and conditions.

Keratin treatments, also known as smoothing treatments, coat the hair with a protein that helps to straighten and smoothen it. While these treatments may not permanently alter the hair structure in the same way relaxers do, they provide a more manageable and straighter appearance temporarily.

Other options, such as permanent waves and perms, are designed to create curls or waves, rather than straighten hair. Thus, they do not fit into the category of chemical hair straightening methods. Blowouts and curl enhancers also serve different purposes in hairstyling and do not involve altering the hair's internal structure with chemicals for straightening effects.

This understanding clarifies why relaxers and keratin treatments are recognized as types of chemical hair straightening methods.
