A cosmetic product designed to deposit a metallic, cool-toned hue onto hair, offering a temporary change in appearance. These formulations coat the hair shaft rather than penetrating deeply, resulting in color that gradually fades over several washes. Examples range from subtle shimmering effects to more pronounced grayscale transformations.
The appeal of this type of product lies in its relatively low commitment and potential for self-expression. It allows individuals to experiment with trending gray shades without the long-term impact associated with permanent dyes. Historically, achieving silver tones often required harsh bleaching processes; however, advancements in color technology have led to gentler, more accessible options that minimize damage while delivering the desired aesthetic.
