The primary purpose of hair color is to enhance or change the natural color of the hair. This can involve deepening the existing color, introducing different shades, or completely altering the hue of the hair. Hair color serves as a means for individuals to express their personality and style, offering opportunities for creativity and transformation. It can also be used to cover gray hair, providing a more youthful appearance or a specific look that aligns with personal preference.

The other options focus on different effects that hair products can have. For example, lightening hair strands without affecting the base color pertains more to specific highlighting techniques rather than the overall purpose of hair color. Adding shine and moisture relates to conditioning treatments that improve hair health rather than altering color. Temporarily brightening the hair ends typically refers to techniques like balayage or temporary color applications, which are just one aspect of the broader aim of hair coloring. Thus, the key function of hair color encompasses the modification of natural hair tones, making it the correct choice.
