Unlock the Secrets: Why Your Hair Turns Green in the Pool
Hair turns green in pools due to a chemical reaction between the hair's keratin and copper ions present in the water. Keratin is a protein found in hair, skin, and nails, while copper is a metal commonly used in pool disinfectants and algaecides.
The reaction occurs when the hair's cuticle, the outermost layer, is damaged and the keratin is exposed. The copper ions then bind to the keratin, forming a green-colored complex. This can happen when hair is exposed to high levels of copper in pool water, such as when the pool is not properly maintained or when there is a high concentration of copper in the source water.
The green tint is usually temporary and will wash out over time. However, if the hair is exposed to high levels of copper for a long period of time, the green color may become permanent. To prevent green hair, it is important to keep pool water properly balanced and to avoid swimming in pools with high levels of copper.
