This guide is designed for you.

What Really Causes Blonde Hair to Turn Green?

It’s Not Chlorine, It’s Copper

Most people blame chlorine, but the green cast is caused by oxidized copper found in many water systems. Copper binds to the hair shaft, especially when the cuticle is open and porous.

Where does the copper come from?

• Aging copper pipes (common in older American homes)
• Algaecides and other pool chemicals
• Some municipal water supplies

Why Blonde Hair Is More Vulnerable

Blonde hair, especially if lightened, is:

• Porous and easily absorbs minerals
• Dehydrated from chemical processing
• Lacking protective melanin, which dark hair has

That makes it a perfect magnet for metal buildup.

How to Prep Your Hair Before Summer Season

Pro-Level Hair Prep

Before the first dip in the pool, take these steps:

• Book a deep-conditioning treatment at your salon
• Use a toning gloss that neutralizes unwanted hues
• Strengthen your hair’s protective layer with protein treatments

At-Home Products That Work

You don’t have to break the bank. These items can be found at your local beauty store or online:

• Leave-in conditioners with UV and chemical shields
• Silicone-based serums that act as water barriers
• Chelating shampoos (like Malibu C Swimmers or Ion Swimmer’s)

These tools help your hair resist mineral absorption and sun damage.
