The appearance of unwanted verdant tones in hair, often resulting from chlorine exposure or certain hair dyes, presents a cosmetic challenge. This discoloration stems from copper oxidation, which binds to the hair protein. The resulting shade is typically undesirable.
Addressing this issue is important for maintaining desired hair color and appearance. The presence of the discoloration can affect self-esteem and the perceived health of the hair. Historically, various methods have been employed, ranging from home remedies to professional salon treatments, reflecting evolving knowledge of hair chemistry and color correction techniques.
