What is the primary effect of reducing disulfide bonds in hair?

The primary effect of reducing disulfide bonds in hair is to alter the hair’s structure. Disulfide bonds are strong chemical bonds that contribute to the hair's shape and integrity. By breaking these bonds through chemical processes, such as those used in relaxing or perming hair, the natural structure and wave pattern of the hair can be changed. This allows for the hair to be reshaped, either straightened or curled, depending on the intended outcome of the chemical treatment. The process alters the overall texture and appearance of the hair, enabling stylists to achieve diverse hairstyles.
