A Professional Hairstylist's Guide to Protecting Your Strands.

As a professional hairstylist, I love when my clients embrace an active lifestyle ~ but one of the most common summer hair issues I see in my chair comes from the pool. That crystal clear water might look refreshing, but the Chlorine keeping it clean can wreak havoc on your hair. Many people assume the dryness they feel after swimming is normal, but what's happening beneath the surface is much more damaging. If you swim regularly - whether for exercise, fun, or relaxation - understanding how Chlorine affects your hair is essential for keeping your strands healthy, strong, and vibrant.

The hidden cost of a pool day.

Chlorine is a powerful disinfectant designed to kill bacteria and keep pools safe. The problem is, your hair isn't immune to its chemical effets.

What Chlorine Does to Your Hair

When hair is exposed to chlorinated water, Chlorine strips away the natural protective oils produced by your scalp. These oils normally keep hair flexible, moisturized, and resilient. Without them, hair becomes rough, porous, and far more vulnerable to damage.

Chlorine also raises the hair cuticle, the outer protective layer of the hair strand. When the cuticle lifts, it allows moisture to escape while making it easier for chemicals and minerals in the water to penetrate the hair shaft. The result? hair feels dry, tangled, dull, and difficult to manage.

The Damage Chlorine Causes & Why It Happens

Over time, repeated exposure to Chlorine can lead to several types of noticeable hair damage.

Extreme Dryness & Brittleness: Because Chlorine removes the scalp's natural oils, hair loses its moisture balance. Without proper hydration, the hair shaft becomes brittle and prone to snapping.

Increased Breakage: When the cuticle layer is weakened and lifted repeatedly, the internal protein structure of the hair becomes compromised. This leads to strands that break easily during brushing, styling, or even washing.

Color Fading: Chlorine is especially harsh on color treated hair. It accelerates color fading by oxidizing the artifical pigments in dyed hair.

Green Tint in Light Hair: Blondes sometimes notice a green tint after swimming. Contrary to popular belief, Chlorine itself isn't green, this discoloration comes from oxidized copper and minerals in the pool water that bind to the hair when the cuticle is open.

Scalp Irritation: Chlorine can disrupt the scalp's natural microbiome and moisture barrier, potentially leading to dryness, flaking, or irritation.

How to Prevent Chlorine Damage

The good news is that a few simple steps can make a huge difference in maintaining your hair health or hair follicle damage.

Saturate Hair with Clean Water Before Swimming: Hair works like a sponge. If it's already filled with clean water, it absorbs less Chlorinated water when you jump into the pool.

Apply A Protective Barrier: Applying a leave-in conditioner, hair oil, or protective cream before swimming creates a barrier that helps shield the cuticle from Chlorine exposure.

Wear A Swim Cap: It may not be glamorous, but a swim cap dramatically reduces Chlorine exposure, especially if you swim frequently.

Rinse Immediately After Swimming: One of the most important steps is rinsing your hair with clean water immediately after getting out of the pool. This helps remove Chlorine before it continues damaging the hair.

Use A Detox Shampoo: Swimmers benefit from using a natural detox shampoo once a week to remove Chlorine and mineral build-up from the hair.

Places To Consider Where Chlorine Hair Damage Occurs

The hair and scalp Chlorine damage can occur not only to the avid swimmers that frequent the pool for laps on a regular basis, but even to the casual pool day can turn from a beautiful blonde to green hues in one swim session. People tend to forget about the steps to take prior to Chlorine exposure while visiting waterslide, lazy rivers and hotel swimming pools.
