"Hair highlights copper" is a physical alteration to hair where strands are intentionally dyed a shade of copper or reddish brown. This technique creates depth, texture, and dimension by contrasting lighter and darker hair tones.
Copper hair highlights are popular for their warmth, vibrancy, and ability to flatter various skin tones. Historically, copper highlights gained prominence in the 1950s when actresses such as Marilyn Monroe and Rita Hayworth showcased this bold and alluring look.
