The discoloration of hair, specifically turning green, after exposure to swimming pool water is a common concern. This phenomenon primarily occurs in individuals with lighter hair shades, such as blonde or grey. The green tint is not directly caused by chlorine, the most prevalent pool sanitizing agent, but rather by the presence of copper in the water. This copper can originate from corroded pipes, algaecides containing copper sulfate, or even source water. The copper binds to the protein in hair shafts, leading to the visible green discoloration. Determining the root cause and implementing appropriate remediation measures are crucial steps in resolving this cosmetic issue.
Addressing this concern promptly is important for both cosmetic and potential hair health reasons. While the copper itself is generally harmless, its presence can indicate underlying water quality issues within the pool, which may require attention. Historically, various home remedies and commercial products have been developed to counteract the effects of copper-induced hair discoloration. The ongoing advancement of hair care technology continues to provide more effective solutions for preventing and removing this discoloration, preserving hair’s natural color and integrity.
