Question: 1 / 400

What is the primary function of hair bleach?

To add shine to the hair

To lighten the natural color of hair

The primary function of hair bleach is to lighten the natural color of hair. Hair bleach works by utilizing chemical agents that penetrate the hair shaft and break down the melanin pigments, which are responsible for the hair's natural color. This process not only lightens the hair, making it appear blonde or a lighter shade, but it can also prepare the hair for further coloring or tonal adjustments.

The other choices do not align with the primary purpose of hair bleach. Adding shine to the hair is typically achieved through conditioning treatments or shine-enhancing products rather than bleach itself. Restoring moisture to the hair is the role of various hydrating treatments and conditioners, while protecting the hair from heat damage falls under the function of heat protectants. Therefore, the correct focus regarding the primary function of hair bleach is on its ability to lighten hair color.
