Many swimmers, especially those with lighter hair, have experienced the dreaded green tinge after a dip in the pool. This isn't some magical transformation; it's a chemical reaction between the chlorine in the pool water and certain elements in your hair. Let's dive into the science behind this common poolside problem.
What Causes Hair to Turn Green in a Pool?
The primary culprit is the interaction between chlorine and metals present in your hair. While chlorine itself doesn't directly turn hair green, it plays a crucial role in the process. Here's the breakdown:
-
Copper: This is the most common offender. Copper ions can accumulate in your hair from various sources, including pool water (from poorly maintained equipment or plumbing), hard water minerals, and even certain hair products. Chlorine reacts with copper, forming a copper chloride compound that deposits on your hair shaft, resulting in a greenish hue.
-
Other Metals: While less frequent, other metals like iron and nickel can also contribute to discoloration. These metals, when combined with chlorine, can produce different shades of green or other unwanted colors.
-
Hair Porosity: The porosity of your hair affects how easily it absorbs minerals and chlorine. Highly porous hair, often damaged or chemically treated, is more susceptible to absorbing these substances, leading to a greater risk of discoloration.
How Can I Prevent My Hair From Turning Green in the Pool?
Preventing that unwanted green tint requires a multi-pronged approach:
1. Pre-Swim Protection:
- Wet Your Hair: Before entering the pool, wet your hair thoroughly with clean water. This helps to fill the hair shaft, reducing the absorption of chlorine and minerals.
- Apply a Leave-In Conditioner: A leave-in conditioner acts as a barrier, preventing chlorine and minerals from penetrating the hair shaft. Choose a conditioner specifically formulated for swimmers.
2. Post-Swim Care:
- Rinse Thoroughly: After swimming, rinse your hair immediately and thoroughly with clean water to remove chlorine and minerals.
- Use a Clarifying Shampoo: A clarifying shampoo is designed to remove buildup from hair, including chlorine, minerals, and product residue. Use this shampoo once or twice a week, or as needed.
- Deep Condition: Regularly deep condition your hair to replenish moisture and repair any damage caused by chlorine.
3. Maintaining Pool Chemistry:
While you can't control pool chemistry directly, you can choose to swim in well-maintained pools that regularly test and balance their water. Properly maintained pools minimize the amount of free copper and other metals present.
Why Does My Hair Turn Green Even After Taking Precautions?
Even with preventative measures, some individuals may still experience green hair. This could be due to several factors:
- High Copper Levels in the Pool: Pools with high levels of copper are difficult to completely avoid discoloration, even with preventative hair care.
- Highly Porous Hair: If your hair is highly porous, it may be more challenging to prevent mineral absorption. Consider using protein treatments to strengthen and seal the hair cuticle.
- Insufficient Rinsing: Thorough rinsing is crucial; failing to remove all chlorine and minerals can lead to discoloration.
Is it Harmful to Have Green Hair from a Pool?
The green discoloration itself is not harmful. It's primarily a cosmetic issue. However, the underlying cause—the presence of chlorine and minerals—can lead to dryness, damage, and breakage over time if not properly addressed with suitable hair care routines.
How Do I Remove Green Hair From a Pool?
Removing the green tint usually involves using a clarifying shampoo or a chelating shampoo, specifically designed to remove metal buildup from hair. In stubborn cases, a professional hair treatment may be necessary. Avoid using harsh chemicals or home remedies that could further damage your hair.
This comprehensive guide should help you understand why hair turns green in the pool and how to prevent and treat it. Remember consistent preventative measures and post-swim care are key to maintaining healthy, vibrant hair.
