Why does my hair turn green after swimming?

Okay, so we know that it happens, but why?

Green hair after swimming in a pool is usually caused by copper compounds in the water.

Copper can make its way into pools through algaecides, copper-based treatments, or even pipes and equipment. When your hair comes into contact with copper-laden water, a chemical reaction occurs, leading to that unwanted green tint.

Here's the science:

When exposed to air and sunlight, copper in pool water oxidises, forming copper compounds. These compounds then bind to the proteins in your hair, resulting in discolouration. Blonde and light-coloured hair is particularly susceptible due to its porous nature, but even brown hair can develop greenish tones.

How to prevent green hair:

✅ Pre-soak your hair with fresh water before swimming to reduce the amount of chlorine or copper your strands absorb.

✅ Pre-condition with a pea-sized amount of TRISWIM Conditioner before putting on your swimming cap for an extra layer of protection.

✅ Wear a tight-fitting swim cap to minimise water exposure and protect your hair from chlorine and copper. We recommend the TRISWIM Seamless Caps for the best fit and comfort.

✅ Rinse with TRISWIM Chlorine Removing Shampoo, specially formulated to eliminate chlorine, copper, and other pool chemicals from your hair.

✅ Follow up with a nourishing conditioner, such as TRISWIM Conditioner, to restore moisture and keep hair soft and healthy.

If you have blonde hair, these steps are especially important, as the greening effect is far more noticeable on lighter tones.

With the right care, you can keep your hair looking fresh, healthy, and (most importantly) not green! 💚💦
