Why Does my Hair Turn Green After Swimming in a Pool?

Green hair after swimming in a pool is often attributed to the presence of copper compounds in the water. Copper can leach into the pool water from various sources, including algaecides, copper-based pool treatments, or even the pipes and equipment. When your hair comes into contact with this copper-laden water, it can result in a chemical reaction that causes the hair to take on a greenish tint.

The copper in the pool water can oxidize when exposed to air and sunlight, forming copper compounds. These compounds can then bind to the proteins in your hair, leading to the green discoloration. Additionally, blonde or light-colored hair is more susceptible to this phenomenon due to its porous nature. However, brown hair can take on greenish tints too.

To prevent green hair, you can take steps such as using a swim cap, rinsing your hair with fresh water before entering the pool, or using specialized shampoos designed to remove chlorine and mineral deposits such as TRISWIM which is formulated to specifically remove chlorine, saltwater, hardwater minerals and bromine found in hot tubs. TRISWIM is a salon quality swimmer’s shampoo, conditioner, body wash and lotion that has been servicing the swim market since 2004 and is sold globally.
