What is the purpose of a hair glaze?

A hair glaze is primarily used to enhance the overall appearance of hair by adding shine and imparting a temporary color. This technique involves applying a semi-permanent treatment that coats the hair shaft, resulting in a glossy finish that makes hair look healthier and more vibrant. The color achieved through a glaze is not permanent and can easily be washed out after several shampoos, making it an appealing option for those looking to refresh their look without a long-term commitment.

The first option suggests that a hair glaze is used to permanently lighten hair; however, glazing treatments do not involve permanent changes to the hair's structure or color. Straightening curly hair, as presented in the third option, is generally achieved through different treatments such as chemical straightening or thermal styling, which are not the same as glazing. Lastly, while some products may help with the appearance of split ends, glazing specifically does not repair the hair but rather enhances its look. The primary function of a glaze is indeed to provide an enhancement in shine and a temporary burst of color.
