The Effects of Chlorine on Your Hair
Chlorine is a chemical disinfectant used to prevent the growth of pathogenic microorganisms in swimming pools. While keeping swimming pools clean and safe is important, pool chlorine also has a harsh effect on hair. Major negative effects of exposure to chlorine in swimming pools include chemical reactions between chlorine and hair proteins, sebum, and the pigments responsible for hair color.
The chlorine present in pool water causes damage to the hair proteins which build the hair shaft. This weakens the structural integrity of the hair shaft, making hair more vulnerable and prone to breakage and split ends. Chlorine also lifts the hair cuticles, making them rough, porous, and difficult to untangle. Additionally, damage to hair done by chlorine is amplified in combination with exposure to sun rays.
Chlorine removes a protective layer of the natural oils that coat the hair shaft, leaving the hair more susceptible to damage. Swimming in chlorinated pools without proper protection can leave hair dry, brittle, and lifeless.
Chlorine acts as a bleaching agent that can remove melanin pigments and lighten your hair color. Chlorine raises the cuticle, allowing minerals to get into the hair and discolor it. People with gray hair may develop brassy tones after swimming in pools regularly. Blonde hair and blonde highlights may even turn greenish after exposure to chlorine.
Swimming in a pool regularly leaves a chemical smell that can linger on your skin and hair -even after taking a shower.
Color-treated, permed, or relaxed hair is particularly vulnerable and needs extra care to prevent and treat damage from pool chlorine.
Fortunately, there are some effective ways to protect hair before swimming and minimize the negative effect of chlorine after swimming sessions. With appropriate protective measures and care, you will not end up with excessively dry, orange, or green hair.

How to Protect Hair Before Entering the Pool
- Use a swimming cap
Use a quality silicone swim cap that fits snugly around your head. A swimming cap will keep your hair dry and protect it from the damaging effects of chlorine.
2. Soak hair in fresh water
To prevent chlorine from reaching your hair, take a short shower before entering the pool. This way you will saturate your hair with fresh water and reduce its ability to absorb pool water.
3. Coat your hair with oil
Apply a generous amount of olive oil or coconut oil before you get in the pool. The oil will coat your strands and create a protective barrier that prevents chlorine damage. You can also soak your hair with an oil-based pre-shampoo treatment such as Huile de Leonor Greyl Pre-Shampoo Oil Treatment.
4. Apply pre-swim conditioner
Before stepping into the pool, saturate your hair with a pre-swim conditioner. This conditioner will coat hair strands and repel chlorine from entering the cuticle.
A special pre-swim conditioner such as AquaGuard Pre-Swim Hair Defense should be applied to damp hair before swimming to protect color-treated hair and keep it safe from the damaging effects of pool chlorine.
How to Treat Your Hair After Swimming in the Pool
- Washing: Wash your hair immediately after a swim. Apply a generous amount of shampoo, massage, and rinse thoroughly. Choose a shampoo specifically designed to remove chlorine and mineral deposits from your hair. Apply conditioner.
- Drying: Do not vigorously rub your hair with a towel, because wet hair tends to be very fragile, especially after exposure to chlorine. Instead, gently blot and squeeze your hair, or just wrap it in a soft towel. Let your hair air-dry, if possible, or use a blow dryer at a lower setting.
- Conditioning: Apply Ion Swimmer’s Leave-in Conditioner to replace lost moisture and make combing easier. Use a wide-toothed comb instead of a brush to avoid stretching wet hair.
- Shampooing: Avoid shampoos that contain sulfates since sulfate-based products can be harsh on your hair. A gentle shampoo formula with moisturizing and nourishing ingredients will keep your hair in good condition.
There are shampoos and conditioners designed for swimmers, which should help reduce the damage done by chlorine and other pool chemicals. These products claim to be effective in preventing chemical buildup, retaining the color, and protecting hair from drying out.
Benefits of using chlorine shampoos:
- Chlorine-removing shampoos help get rid of the chemicals that accumulate in the hair after swimming in pool water. Using chlorine shampoo twice a week should be enough to minimize the harmful effects of pool chlorine.
- Chlorine shampoos prevent silver and blond hair from turning yellow and keep the green tint at bay.
- Swimmers’ shampoos also help eliminate the chemical smell of chlorine-exposed hair.
- Chlorine shampoos keep hair from drying out by sealing in moisture and leaving your tresses smooth and shiny. After eliminating chemical buildup, your hair is less tangled and easier to comb.
