What type of product is used to achieve straight hair by breaking down the curl structure?

A chemical relaxer is specifically designed to break down the curl structure of the hair, allowing it to become straighter. These products typically contain strong chemicals that alter the protein structure of the hair, which enables the curls or waves to be loosened or eliminated.

When applied to the hair, the relaxer penetrates the cuticle and breaks the disulfide bonds between the keratin proteins, effectively straightening the hair. This process is particularly beneficial for individuals with naturally curly or wavy hair who desire a smoother, straighter look.

In contrast, a hair straightener refers to a styling tool rather than a product; it uses heat to temporarily straighten hair without changing its internal structure. Conditioning treatments and moisturizing serums focus on improving hair health and hydration but do not alter the curl structure or achieve straightness. They may help in maintaining straightened hair, but they do not perform the chemical restructuring necessary for long-term straightening.
