A hair product designed to neutralize unwanted yellow or brassy tones in blonde, silver, gray, or highlighted hair. These products typically contain violet or blue pigments that counteract these warm hues, restoring brightness and vibrancy to the hair color. For example, individuals with naturally gray hair may use this type of mask to eliminate yellowing caused by environmental factors or product buildup.
The significance of these color-correcting treatments lies in their ability to maintain the desired cool tones of treated hair. The benefits include enhanced color clarity, improved overall hair appearance, and extended intervals between professional salon visits for color touch-ups. Historically, similar methods have been employed using natural ingredients to achieve similar effects, but modern formulations offer more targeted and consistent results.
