When your hair is exposed to copper or chlorine, it can cause the cuticle to lift, allowing the color to penetrate and resulting in that lovely green tinge. It's not just limited to swimmers, though - people who use mineral-rich shampoos or live in areas with high copper levels in the water can also experience this funky phenomenon.
But here's the thing: it's not all bad news! A green tinge can actually be a sign that your hair is trying to protect itself from damage. It's like your hair is wearing a tiny little shield to deflect all the harsh chemicals and environmental stressors it's exposed to.
