What is the method called that enhances the natural color of hair through washing?

The method that enhances the natural color of hair through washing is referred to as a color refresher. This technique typically involves a product that deposits a small amount of pigment while cleansing, helping to revitalize the hair's natural shade. It can add shine, enhance vibrancy, and may even offer some slight color correction without the permanence of traditional coloring methods.

Color refreshers are especially beneficial for maintaining color-treated hair between salon visits, providing a boost to the overall tone and making the hair appear healthier and more vibrant. Using this method allows for a gentle and non-damaging approach to enhancing color, as it often contains conditioning agents that support hair health while imparting color.
