Why Blonde Hair Turns Green in Pools and How to Fix It

Blonde hair and swimming pools can be a challenging combination in summer—no one wants their bright locks to take on an uninvited green tint. It’s a common belief that chlorine is the culprit. However, the real source of the problem lies elsewhere. Understanding why this happens is key to keeping your hair healthy and vibrant all season long.

Why Does Blonde Hair Turn Green in Pools?

The answer lies in one word: copper. Just like copper turns the Statue of Liberty green, trace amounts of copper in pool water can oxidize, resulting in an unwanted green tint on hair.

How Does Copper Get in Pool Water?

Copper can end up in pool water in several ways:

1. Water Source: If you use well water or even some municipal water sources to fill your pool, it may already contain copper.

2. Algaecides: Many algaecides use copper as an active ingredient to eliminate algae. However, when it bonds with chlorine, copper can also bind to the proteins in hair strands and create that greenish tint.

3. Mineral Sanitizers: Copper is also a common ingredient in some mineral sanitizers, added for its algae-fighting power.

Will Blonde Hair Turn Green in a Saltwater Pool?

Yes, this can also happen in saltwater pools. While saltwater pools generate their own chlorine, the presence of copper in the water can still lead to hair discoloration when oxidized.

How to Prevent Blonde Hair from Turning Green

Fortunately, you can avoid the green effect without giving up on pool fun.

1. Test Your Water Source: Use test strips or a water testing kit to check for copper in the water you’re using. You can also have a local pool store test it.

2. Use a Hose Filter: If your water source contains copper, attach a hose filter while filling the pool. This step will help keep out unwanted minerals.

3. Add a Metal Sequestrant: This pool additive binds to metals like copper, preventing them from oxidizing and turning hair green.

4. Opt for a Copper-Free Algaecide: When treating algae, consider using an algaecide that doesn’t rely on copper.

5. Wear a Swim Cap: It may not be the trendiest option, but a swim cap offers direct protection against pool chemicals and prevents copper from bonding with your hair.

6. Pre-Swim Hair Prep: Apply a leave-in conditioner or rinse with apple cider vinegar to create a protective barrier on your hair strands before entering the pool.

7. Wash Immediately After Swimming: Rinse your hair thoroughly as soon as you leave the water to reduce the chance of copper binding with your hair.

How to Remove Green Tint from Hair

If your hair has already picked up that green hue, these methods can help restore its natural color:

1. Swimmer’s Shampoo: Choose a shampoo with chelating agents to help remove metals from your hair.

2. Lemon Juice Rinse: Citric acid in lemon juice helps remove oxidized copper. Rinse your hair with lemon juice, then condition.

3. Apple Cider Vinegar: The acetic acid in apple cider vinegar can also help remove copper. After swimming, give your hair a rinse with apple cider vinegar to reduce any green tones.

4. Baking Soda Paste: Mix baking soda and water to make a paste, apply it to your hair, rinse, and then shampoo and condition as usual.

5. Crushed Aspirin: Dissolve six to eight crushed aspirin tablets in warm water, apply the solution to your hair, and let it sit for 15-20 minutes before rinsing.

6. Ketchup or Tomato Juice: The acids in ketchup or tomato juice can help neutralize green tones. Apply to hair, let sit, and rinse thoroughly.
