## Houston’s Heatwave: Is Tap Copper Crashing Hair?

The humidity hangs heavy in Houston, a tangible presence that clings to everything. It’s not just uncomfortable; it’s a beauty disruptor. This summer’s relentless heatwave is exacerbating a problem many Houston residents face: copper buildup in their hair from the city’s tap water. This isn’t just about aesthetics; it’s about hair health.

Houston’s aging infrastructure, while undergoing improvements, can leach copper into the water supply. This copper, combined with the increased sweating and frequent washing during a heatwave, creates a perfect storm for hair damage. The result? Brittle, discolored, and unmanageable hair.

Let’s dive into how Houstonians can combat this copper crisis, focusing on practical, affordable solutions.

First, know your enemy. Copper buildup manifests differently depending on your hair color. Blondes might notice a greenish tint, while brunettes may experience a dull, brassy tone. Redheads might see their color become muted and less vibrant. All hair types, however, can suffer from increased dryness and breakage.

The first step is testing your water. While a comprehensive lab test is ideal, it can be expensive. A more budget-friendly option is a home water testing kit specifically designed to detect heavy metals like copper. You can find these at most hardware stores in the Houston area, including Lowe’s and Home Depot, or online retailers like Amazon. Look for kits that specifically mention testing for copper.

These kits typically involve collecting a water sample and using a reagent to indicate the presence of copper. While not as precise as a lab test, they provide a good indication of whether you have a copper problem. Remember to test water from different taps in your home, as copper levels can vary.

If your test indicates high copper levels, consider a shower filter. These filters attach directly to your showerhead and can remove a significant amount of copper and other impurities. Look for filters that use KDF-55 media, which is particularly effective at removing heavy metals. Brands like AquaBliss and Culligan are readily available at stores like Target and Walmart in Houston.

Now, let’s talk about chelating shampoos. These shampoos contain ingredients that bind to copper and other metals, allowing them to be washed away. Look for shampoos containing EDTA (ethylenediaminetetraacetic acid), phytic acid, or citric acid.

A great, affordable option available at most Houston drugstores (CVS, Walgreens) is the Malibu C Hard Water Wellness Shampoo. It’s specifically formulated to remove mineral buildup and is gentle enough for regular use. Another option is the Kenra Clarifying Shampoo, which contains grapefruit extract, a natural chelating agent.

Important Note: Chelating shampoos can be drying, so it’s crucial to follow up with a deep conditioning treatment.

Speaking of deep conditioning, let’s explore some DIY options perfect for restoring moisture balance after using a chelating shampoo.

Here’s a simple yet effective recipe:

1 ripe avocado
2 tablespoons coconut oil (melted)
1 tablespoon honey

Mash the avocado until smooth, then mix in the coconut oil and honey. Apply to damp hair, focusing on the ends. Cover with a shower cap and leave on for 20-30 minutes. Rinse thoroughly and style as usual.

Avocado is rich in fatty acids and vitamins that help to nourish and hydrate the hair. Coconut oil penetrates the hair shaft, reducing protein loss and adding shine. Honey is a humectant, meaning it attracts moisture to the hair.

For those with color-treated hair, the copper buildup can significantly alter the color. Consider using a color-depositing conditioner to refresh your color and counteract any brassiness or green tones. For blondes, a purple conditioner can help neutralize yellow tones caused by copper. For brunettes, a blue conditioner can help counteract orange tones.

Challenge Alert: Over-chelating can also damage your hair. Using chelating shampoos too frequently can strip your hair of its natural oils, leading to dryness and breakage. Limit your use of chelating shampoos to once or twice a week, depending on the severity of your copper buildup.

Another common mistake is not using a clarifying shampoo before coloring your hair. Copper buildup can interfere with the coloring process, resulting in uneven color or a color that doesn’t last as long. Always clarify your hair with a chelating shampoo a few days before coloring to ensure optimal results.

Real-World Scenario: Imagine you live in the Heights neighborhood of Houston, known for its older homes and potentially older plumbing. You’ve noticed your blonde highlights are starting to look brassy and dull. You suspect copper buildup.

Purchase a home water testing kit from the Lowe’s on Yale Street.
Test your shower water and confirm the presence of copper.
Install a shower filter from Target on Shepherd Drive.
Start using the Malibu C Hard Water Wellness Shampoo once a week.
Follow up with the DIY avocado deep conditioning treatment.
Use a purple conditioner once a week to maintain your blonde highlights.

By following these steps, you can effectively combat copper buildup and restore your hair’s health and vibrancy, even during a Houston heatwave.

Don’t underestimate the power of a healthy diet and hydration. Drinking plenty of water helps to flush out toxins and keep your hair hydrated from the inside out. Eating a balanced diet rich in vitamins and minerals provides your hair with the nutrients it needs to grow strong and healthy.

Finally, consider consulting a professional. If you’re struggling to manage copper buildup on your own, consider consulting a hairstylist or trichologist (a hair and scalp specialist) in the Houston area. They can assess your hair and scalp and recommend a personalized treatment plan. Many salons in the Galleria area offer specialized treatments for removing mineral buildup.

Remember, combating copper buildup is an ongoing process. By taking proactive steps to test your water, use chelating shampoos, deep condition your hair, and maintain a healthy lifestyle, you can keep your hair looking its best, even in the face of Houston’s challenging water conditions and relentless heat. Don’t let copper win!
