Phoenix Pools: Salt Systems Stealing Hair Color?

By Franklin Everett Shaw

Is your blonde turning green after a dip in your Phoenix pool? You’re not alone. Many Phoenix residents with color-treated hair face this frustrating problem, especially those with saltwater pools. But don’t despair! Understanding the science behind the discoloration and taking proactive steps can keep your locks looking vibrant.

The culprit isn’t always chlorine, despite popular belief. In Phoenix, a perfect storm of factors contributes to this hair-raising issue.

First, let’s talk about chlorine. While chlorine itself doesn’t turn hair green, it can exacerbate the problem. Chlorine oxidizes metals in the water, particularly copper.

Phoenix water, even after treatment, can contain trace amounts of copper from aging pipes. Saltwater pools, while using a salt chlorine generator, still produce chlorine.

The real issue arises when the pool’s pH is out of whack. In the desert climate of Phoenix, evaporation is rampant, leading to increased mineral concentration and pH fluctuations.

High pH levels (above 7.6) cause copper to dissolve more readily into the water. This dissolved copper is what binds to the protein in your hair, resulting in that dreaded green tint.

Another factor specific to Phoenix is the use of copper-based algaecides. Many pool owners in the Valley of the Sun rely on these to combat algae growth in the intense sunlight.

While effective, these algaecides significantly increase the copper levels in the pool water, making green hair a near certainty for color-treated individuals.

So, what can you do? Let’s break it down into actionable steps.

Step 1: Test Your Water Regularly.

Invest in a reliable pool water testing kit. Taylor Technologies kits are highly recommended for their accuracy.

• Check your pH, chlorine, alkalinity, and copper levels at least once a week.
• Aim for a pH between 7.2 and 7.6.
• Keep chlorine levels within the recommended range for your saltwater system (usually 1-3 ppm).
• If copper levels are high (above 0.2 ppm), take action immediately.

You can purchase these kits at Leslie’s Pool Supplies or online. Bring a water sample to your local pool supply store for a professional analysis if you’re unsure.

Step 2: Balance Your Pool Chemistry.

Adjust your pH using pH increaser (sodium carbonate) or pH decreaser (sodium bisulfate), following the product instructions carefully. Add chemicals gradually and retest after each adjustment.

Consider using a phosphate remover. Phosphates are a food source for algae, and reducing them can lessen the need for copper-based algaecides.

If you must use an algaecide, opt for a non-copper alternative. Polyquat algaecides are a good choice.

Step 3: Protect Your Hair Before Swimming.

Wet your hair with tap water before entering the pool. This saturates the hair shaft, preventing it from absorbing as much copper-laden pool water.

Apply a leave-in conditioner or hair oil. These create a barrier that further protects your hair.

Wear a swimming cap. This is the most effective way to prevent your hair from coming into contact with the pool water.

Local Phoenix salons, like Rumors Salon and The Root Salon, often recommend specific preventative products. Ask your stylist for recommendations tailored to your hair type and color.

Step 4: Rinse and Treat Your Hair After Swimming.

Rinse your hair immediately after getting out of the pool. Use a clarifying shampoo to remove any residual chlorine and copper.

Use a chelating shampoo specifically designed to remove mineral buildup. Malibu C Hard Water Wellness Shampoo is a popular and effective option.

Follow with a deep conditioner to replenish moisture. Color-treated hair is often dry and porous, making it more susceptible to damage.

Step 5: Consider Professional Pool Maintenance.

If you’re struggling to maintain your pool chemistry, consider hiring a professional pool service. Companies like Aquaman Pool Service and Phoenix Pool Patrol offer weekly or bi-weekly maintenance plans.

• Pros: Consistent water testing and balancing, expert advice, reduced risk of hair discoloration.
• Cons: Cost, reliance on a third party.

Be sure to ask potential pool service providers about their experience with saltwater pools and their approach to preventing copper buildup.

Common Mistakes and Pitfalls:

• Over-reliance on algaecides: Using copper algaecides as a quick fix without addressing the underlying cause of algae growth (e.g., high phosphates, poor circulation) will only exacerbate the problem.
• Ignoring pH: Neglecting pH balance is the biggest mistake. Even with low copper levels, a high pH can cause discoloration.
• Infrequent water testing: Testing your water only occasionally won’t give you an accurate picture of its chemistry. Regular testing is crucial for preventing problems.
• Using cheap testing strips: Inexpensive testing strips are often inaccurate. Invest in a quality testing kit or take your water to a professional for analysis.

DIY Solutions (Use with Caution):

Some people swear by DIY remedies like tomato juice or vinegar rinses to remove green tones. These can work in mild cases, but they can also be damaging to your hair if used improperly.

• Tomato juice: The acidity in tomato juice can help to neutralize the copper. Apply to wet hair, leave on for 30 minutes, and rinse thoroughly.
• Vinegar rinse: Mix 1 part vinegar with 3 parts water. Apply to wet hair, leave on for 5 minutes, and rinse thoroughly.

Always test these remedies on a small, inconspicuous strand of hair first to ensure they don’t cause any adverse reactions.

Long-Term Solutions:

Consider installing a whole-house water filter. This can reduce the amount of copper entering your pool in the first place.

If you have copper pipes, consider replacing them with PVC or PEX. This is a more expensive option, but it can eliminate the source of copper contamination.

Ultimately, preventing green hair in Phoenix saltwater pools requires a multi-faceted approach. Regular water testing, proper chemical balance, preventative hair care, and, if necessary, professional assistance are all essential. By taking these steps, you can enjoy your pool without sacrificing your hair color.
