How it happens:
* Copper: The green tint usually appears on hair that has been previously bleached or lightened. This is because bleached hair is porous and absorbs substances more easily. Copper ions in the water can attach themselves to the hair shaft, causing a greenish discoloration.
* Chlorine: Chlorine itself doesn't directly cause the green color. However, chlorine can interact with copper ions in the water, making them more readily available to be absorbed by your hair.
Who is most at risk:
* People with light blonde or bleached hair: As mentioned, bleached hair is most susceptible due to its porous nature.
* Swimmers: People who swim frequently in chlorinated pools are more likely to experience this problem.
Preventing Green Hair:
* Wet your hair before swimming: This helps to minimize the amount of chlorine that can penetrate your hair.
* Use a leave-in conditioner: This helps to seal the hair cuticle and reduce absorption of copper ions.
* Wear a swim cap: This creates a barrier between your hair and the pool water.
* Use a clarifying shampoo: After swimming, use a clarifying shampoo to remove any remaining chlorine and copper.
Fixing Green Hair:
* Use a clarifying shampoo: A clarifying shampoo can help to remove some of the green discoloration.
* Use a color-correcting shampoo or toner: These products are specifically designed to neutralize brassy or green tones in the hair.
* Try a hair mask: Some homemade hair masks with ingredients like lemon juice or baking soda can also help to remove the green tint.
Important Note: Always consult with a professional hairstylist if you're concerned about green hair. They can advise you on the best course of action for your hair type and situation.
