Is Swimming Bad for Hair? 9 Best Baby Hair Care Tips Against Chlorine

This time of the year is the ideal time for little ones to enjoy water play in sunny Singapore. But is swimming bad for hair? The short answer is yes: Chlorine can leave it dry, brittle, and tangled. But don’t worry – This guide gives parents simple yet practical ways to keep their baby’s delicate locks soft, strong, and healthy, even with daily dips in the pool.

Effects of Chlorine on Your Baby’s Hair

Chlorine is added to kill germs, bacteria, and viruses that can cause infections. It’s the most common way to disinfect swimming pools. Even though chlorine is important for hygiene, it has several effects on your baby’s hair that you should consider:

• Makes hair prone to breakage: Chlorine removes the hair’s natural protective oils, leading to dryness and brittleness. Without oils, hair becomes fragile and can break easily^[1].
• Causes tangling and frizz: Chlorine roughens the hair cuticle, making hair tangled and frizzy.
• Can cause discolouration: Especially in light-coloured hair, chlorine can react with minerals, causing a greenish tint.

A 2024 report by Cleveland Clinic confirms that chlorine doesn’t just affect hair, it can also weaken nails by removing their protective oils, making them brittle. Even your baby’s eyes can get irritated or red after swimming in chlorinated pools^[2].

In some cases, repeated exposure without proper protection can strip away the skin’s natural barrier, making it more vulnerable to irritation, redness, and flare-ups of conditions like eczema.

Casual swimmers, those who take a dip once a year on holiday, might not notice much impact from chlorinated water. But if you swim more regularly, even just once a month, chlorine can start to take a toll, especially if your hair is more vulnerable to damage. Certain hair types are more prone to chlorine-related issues, including:

• Thin or fine hair
• Colour-treated or bleached hair
• Chemically-treated hair
• Naturally dry or damaged hair

That’s why, no matter how often they swim, it’s important to take steps to protect their hair from chlorine exposure.

9 Tips to Protect Your Baby’s Hair

Before Swimming

• Wet hair first: Saturate your baby’s hair with clean water before they enter the pool. Wet hair absorbs less chlorine^[2].
• Apply hair oil to form a protective layer against chemicals and pollutants in the swimming water. This act also prevents damage to the hair fibres, and follicles.

During Swimming

• Wear a swim cap: Swim caps are ideal for preventing chlorine from reaching your baby’s hair in the first place. For the best protection, place the cap over wet hair and be sure all of the hair is covered inside.
• Use protective hairstyles: If your baby has long hair and isn’t wearing a cap, pull it back into a tight ponytail, braid, or bun. This tip will limit their exposure to chlorine.
• Choose outdoor pools: When possible, swimming in an outdoor pool is the best option. In an outdoor pool, chlorine from the water evaporates into the air more quickly. It reduces the concentration in the water and ultimately the amount of chlorine that can be absorbed into your baby’s hair and skin^[3].

Post Swimming

• Rinse immediately: Even if your baby doesn’t have time to shower immediately after swimming, a quick rinse can help. Running clean water through their hair will remove some of the saltwater or chemicals.
• Use Little Étoile SwimProtect: This gentle, protective cleansing shampoo is for use after each swimming activity. It removes/neutralises chlorine and has been proven in scientific testing, helping to protect hair from damage caused by chlorine.

Bonus point: Our SwimProtect also helps to remove the lingering chlorine smell, plus it has a lively fruit smell – leaves hair and skin feeling and smelling fresh, not like a swimming pool.

• Deep condition and seal: Reapply a baby-safe leave-in conditioner and follow up with a gentle detangler or nourishing oil.

Quick Checklist

With a little preparation and the right baby hair care routine, you can keep swimming fun and safe for your little one. The key is consistency and using gentle, protective products designed especially for babies.

By following these steps, you can help repair and protect your baby’s hair from the effects of chlorine exposure.

FAQs

Is it bad to swim with your baby’s hair up?

No, it is not bad – in fact, putting your baby’s hair up in a bun, ponytail, or braids before swimming is recommended. Securing hair in a protective style helps minimize tangling, reduces direct exposure to chlorine or saltwater, and makes post-swim care easier.

Will swimming once a week damage baby hair?

Swimming once a week is unlikely to cause significant damage to your baby’s hair if you follow proper hair care routines. Rinsing hair before and after swimming, using gentle shampoo, and keeping hair moisturized will help prevent dryness and brittleness from chlorine exposure.
