A color-depositing product formulated to refine and adjust the shade of light, grey, or white hair. This product category works by neutralizing unwanted yellow or brassy tones, shifting the overall hue towards a cooler, more silvery appearance. For example, application can transform hair with a yellowish cast to a brighter, more aesthetically pleasing grey.
The application of such refining agents is valuable for maintaining the desired cool tone and preventing discoloration caused by environmental factors, styling products, and hard water. Historically, women seeking to conceal grey hair relied on permanent dyes; however, these specialized products offer a less damaging alternative for enhancing and managing the unique characteristics of naturally grey or silver hair, allowing for tonal adjustments without significant chemical alteration of the hair shaft.
