Metallic hair dye, a type of hair colorant, adds metallic pigments to hair, imparting a lustrous, iridescent effect. Its popularity soared in the 1980s punk and new wave subcultures, as exemplified by Cyndi Lauper's signature platinum-silver hair.
Metallic hair dyes enhance hair's shine, provide dimensional color, and can conceal gray hairs. Their popularity is attributed to their ability to create edgy, unconventional looks and their versatility in complementing various skin tones.
