Chlorine vs. Colored Hair: How to Protect Your Color This Summer

How can you protect coloured hair from chlorine this summer? You can keep your tailored colour vibrant by wetting your hair with fresh water before swimming and rinsing it immediately after. At All About Salon, we want you to enjoy sunny days by the pool without worrying about dull, dry strands, so here is our expert advice on maintaining beautiful hair health all season long.

What does chlorine do to coloured hair?

Chlorine is a chemical used to keep pool water clean. While it’s great for hygiene, it can be harsh on your hair-especially if you have coloured hair. Knowing what it does helps you protect your strands before the damage starts.

How does chlorine interact with hair dye?

Chlorine can lift and rough up the outer layer of your hair, known as the cuticle. When this happens, colour molecules slip out, causing your beautiful shade to fade. It also strips away natural oils, leaving your hair feeling dry and stiff. Any dye can fade from pool water, so protecting it is important.

Why are blonde and light shades more affected?

Blonde and lighter shades often have a harder time with pool water. Lightened hair is more porous, meaning it soaks up chemicals easily. This can push your fresh blonde into unwanted warm, yellow, or brassy tones.

Does chlorine impact different colours differently?

Yes, it does. While every shade can fade, red dye is famous for losing its brightness quickly, and swimming speeds that up. Dark browns and blacks might not show fading as fast, but they can still become dull, dry, and more prone to breakage over time.

Is the green tint from swimming pools real?

Yes, green hair after swimming is a real thing, especially for blondes. However, it’s usually caused by copper in the water, not just chlorine. The chlorine reacts with the copper, making it stick to porous hair. A good pre-swim routine is the best way to stop this before it starts.

What risks does chlorine pose to hair health and colour?

Beyond fading your colour, pool water can change how your hair looks, feels, and holds up over the summer.

How quickly does colour fade with regular swimming?

This depends on how bright the dye is, how porous your hair is, and how often you swim. If you’re taking a dip several times a week, your colour can start looking flat and washed out fairly quickly without the right protection.

Can chlorine dry or damage hair structure?

Absolutely. Chlorine removes the natural oils that keep your hair soft and flexible. Without these oils, your hair feels rough, dry, and is more likely to snap. Because coloured hair needs extra care, it often shows this damage sooner.

Is scalp irritation from pool water common?

It can be. Pool chemicals can dry out your scalp, leading to itchiness or flakiness. If you notice irritation that doesn't go away, we suggest speaking with a doctor for personalised advice.

How can you prepare coloured hair before swimming?

Stopping damage early is the secret to a confidence-boosting summer. Here are a few simple steps to protect your hair before you jump in.

Should you wet your hair before entering the pool?

Yes! Always rinse your hair with clean, cool water before getting into the pool. Hair that’s already full of fresh water won't absorb as much chlorine. Cool water also helps keep your hair cuticle flat, adding another layer of protection.

Do pre-swimming conditioners or oils make a difference?

They make a huge difference. Applying a nourishing leave-in conditioner or hair oil acts like a shield over your strands. This blocks chlorine and copper from soaking in. We recommend applying it from the mid-lengths to the ends, where your hair is usually the driest.

Are swim caps effective for protecting hair colour?

A swim cap is a fantastic way to protect your hair health. While it might not keep your hair completely dry, it greatly limits how much pool water touches your strands. For the best results, try this easy routine:

• Wet hair with fresh water first
• Apply a conditioner or oil barrier
• Wear a swim cap

This combo gives you the ultimate protection.

What’s the best way to care for coloured hair after swimming?

Your after-swim routine is just as important as your prep. The longer pool chemicals sit in your hair, the more they dry it out.

Should you rinse immediately after swimming?

Yes. Rinse your hair within 60 seconds of leaving the pool. Use cool or lukewarm water, as hot water can open the cuticle and cause more fading. A quick rinse washes away chlorine before it settles in.

What types of shampoo and conditioners should you use?

We recommend using professional, colour-safe products like the Evo haircare range. Their sulfate-free shampoos and nourishing conditioners gently cleanse your hair while locking in moisture and protecting your tailored colour from fading out.

Are clarifying or swimmer-specific shampoos safe for dyed hair?

Standard shampoos often struggle to wash away pool chemicals. A gentle clarifying or swimmer's shampoo is very helpful for removing chlorine and mineral build-up without stripping your colour. Massage it in from the roots to the ends, leave it for a minute, and rinse well. Never leave pool water in your hair overnight!

Which products help protect and maintain colour-treated hair in summer?

Using quality products at home is key to maintaining a fresh, modern style between salon visits.

Are colour-safe and UV-filtering products necessary?

Yes, they are. Summer sun can fade your colour and weaken your hair just like pool water. UV-filtering sprays and colour-safe products act like sunscreen for your hair, keeping your shade bright and your strands strong.

How do leave-in conditioners and serums prevent fading?

Leave-in treatments provide all-day hydration and protection. A professional styling product or leave-in conditioner smooths your hair, adds shine, and creates a light barrier against sun, salt, and chlorine. Just apply a little before you head out for the day.

Can weekly treatments restore vibrancy and moisture?

Absolutely. Summer elements can leave your hair feeling tired. Using a deep conditioning mask once a week, such as Evo's Fabuloso treatments, helps replace lost moisture, reduce frizz, and keep your hair strong and shiny all season.

What are practical tips for keeping your colour vivid all summer?

Good daily habits go a long way in keeping your hair looking its best.

Should you limit heat styling and sun exposure?

Yes. Heat tools can put extra stress on your hair. Try embracing a relaxed, natural look with braids or a messy bun. If you must use heat, always apply a protectant. When out in the sun, pop on a stylish hat to protect your hair and face.

How often should you schedule salon touch-ups during summer?

Summer speeds up colour fading, so regular visits help maintain your look. We usually recommend booking a stylist consultation or touch-up every 4 to 6 weeks. If you notice your colour fading faster, our expert stylists are here to offer expert advice tailored to your hair goals.

Does saltwater or sun have a similar effect as chlorine?

Yes, saltwater and UV rays can be just as drying. Saltwater pulls moisture out, causing frizz, while the sun weakens the cuticle. A good haircare routine should tackle all three of these summer stressors:

Frequently asked questions about chlorine and coloured hair

Here are some clear, helpful answers to the questions we hear most often in our Surry Hills salon.

How often can you swim without damaging coloured hair?

With a consistent routine, you can swim daily and still enjoy beautiful hair. Just remember the basics:

• Wet hair with fresh water before swimming
• Use a protective conditioner or oil
• Rinse straight after
• Use a swimmer’s shampoo and a colour-safe conditioner

While frequent swimmers might see a little fading, these steps make a massive difference.

What shades are most at risk of chlorine damage?

Blondes and lightened hair are the most delicate because they easily pick up green copper tones. Red shades also lose their vibrancy quite fast. Highly processed hair generally needs the most care to stay hydrated.

Can you fix green or brassy tones after swimming?

Yes, we can help! A gentle clarifying shampoo can wash away the mineral build-up that causes green tints. For brassiness, a professional toning shampoo works wonders to balance out yellow tones. If your colour needs a little more help, our stylists are ready to provide a tailored colour correction to get you back to looking your best.
