How does a hair glaze treatment primarily benefit hair?

A hair glaze treatment primarily benefits hair by adding shine and enhancing color vibrancy. This treatment typically involves a semi-permanent formula that coats the hair strands, which not only provides a boost of moisture and shine but also enhances the existing color without making drastic changes.

When applied, the glaze can help to penetrate the cuticle, resulting in a reflective surface that enhances shine. It also works to brighten and enrich the existing color, making it appear more vibrant. This is particularly advantageous for those who want to refresh their hair's appearance or add a glossy finish, without the commitment of permanent color changes or chemical alterations.

The other options do not accurately reflect the primary benefits of a hair glaze. For example, while some treatments can assist with split ends or add volume, these are not the main objectives of a glazing treatment. Instead, it focuses more on enhancing the overall look and feel of the hair through shine and color vibrancy.
