A cosmetic treatment, often a semi-permanent color or a tinted gloss, imparts a cool, shimmering tone to the hair. This technique is primarily employed to neutralize brassy or yellow undertones in blonde, gray, or highlighted hair, resulting in a brighter, more refined appearance. As an example, individuals with naturally graying hair might use such a product to enhance the silver tones and diminish any dullness.
The application of this method is valued for its ability to refresh and revitalize hair color without the commitment of permanent dye. It serves to correct unwanted warmth, enhance existing cool tones, and add noticeable shine. Historically, techniques to alter or enhance hair color have existed for centuries, with modern formulations offering more controlled and subtle results than earlier methods. This approach to hair coloring provides a non-damaging option, suitable for regular use.
