Calcium thioglycolate is commonly used in cosmetology for its hair straightening properties, making it a popular choice in the formulation of relaxers and perms. This chemical works by breaking down the disulfide bonds in the hair’s keratin structure, allowing the hair to be reshaped and straightened. The effectiveness of calcium thioglycolate in altering the hair's structure is particularly beneficial for clients seeking a smoother, straighter hairstyle or when managing curly or frizzy hair. Its specific ability to modify hair's texture is why a cosmetologist would choose to use this compound over others, especially when straightening or relaxing hair is desired.

Other options, such as fragrance, exfoliating, or coloring effects, do not accurately represent the primary function and application of calcium thioglycolate in cosmetological practices. While a cosmetologist may consider various factors when choosing hair treatment products, the key functionality of calcium thioglycolate lies in its ability to alter hair texture through chemical processes.
