What is the effect of hydrogen peroxide in nail services?

Hydrogen peroxide is commonly used in nail services primarily for its whitening properties. When applied to nails, it can help remove stains and discoloration, resulting in a brighter and cleaner appearance. The agent works by breaking down and oxidizing the pigments that cause the yellow or dull look of nails, leading to a more aesthetically pleasing finish.

While some products may claim to strengthen or soften nails, hydrogen peroxide is not primarily used for these purposes in nail care routines. It is also not known to add shine; rather, its focus lies solely on whitening. Therefore, the correct answer highlights the primary attribute of hydrogen peroxide as a whitening agent in nail services.
