Last Updated on October 17, 2021

Swimming is great exercise and very healthy for your body but does the chlorine in most pools adversely affect your skin? Is pool chlorine bad for your hair too?

The answer is yes for both.

Chlorine and Hair: What You Should Know First

Chlorine is a chemical found in most swimming pools that helps keep swimmers safe from bacteria, viruses, and infections. This pool chemical can leave a distinct odor on clothes, skin, and hair after taking a dip – not enough to cause permanent damage but it can dry out your locks or leave you with irritated red skin.

Is Pool Chlorine Bad for Your Hair?

Chlorine is very drying for your hair and skin because it takes the natural oils that your hair and skin need to remain healthy out when you are in the water. Chlorine can leave your hair rough, frizzy, dry, and very damaged.

Chlorine can also cause chemical reactions to occur in your hair which can change the natural color or change up the color you just had put in by your hairstylist. The hair actually ends up green from copper in the water that has been oxidized by the chlorine and when that is absorbed into your hair strands it can leave your hair with a green tint to it.

Why Pools Have Chlorine in the First Place

According to, Brown University began using chlorine to clean its swimming pool all the way back in 1910. It is remembered as the first attempt to sanitize pools in the United States.

Chlorine is added to the pool water to kill the many germs that are brought in by the people who swim in the pool. It is an important and needed chemical in pool water to cut down on the spread of diseases and illnesses, especially at crowded pools, and also helps eliminate algae growth in a pool, according to

How to Prevent Chlorine Damage to Your Hair

Damage from chlorine does not have to be permanent because there are several ways to reduce the amount of chlorine that gets into your hair strands. Here are some suggestions you can do before and after you swim to prevent chlorine hair damage.

Wet your hair first

Since hair soaks up water quickly, it is good to wet your hair before you jump in a pool. This will help prevent the chlorine-filled pool water or damaging saltwater for that matter, from being absorbed into your hair.

Wear a swim cap

It may seem old-fashioned, but swim caps are still important to wear when swimming. You can enjoy swimming in a pool or saltwater without getting your hair wet at all. You can also wet your hair with regular water first then put on the swim cap since the wet hair will create a tighter seal of the swim cap to your head, keeping out the damaging chlorine water even better.

Use a leave-in conditioner before entering the pool

You can opt to apply a leave-in style conditioner before jumping into a chlorine pool which will help lessen the amount of chlorine that gets soaked into your hair. The conditioner will also moisturizer your hair while you are swimming so it is a win-win solution.

Apply oil

Apply some coconut oil or olive oil to your hair then put on a swim cap before getting in the pool to help prevent chlorine from infiltrating your hair strands. The oil will repel the water and does not allow as much chlorine water to soak into your hair.

Rinse your hair immediately

You should always rinse your hair after leaving the pool for the day. There are usually showers near the pool area which means you can easily wet your hair down before getting in the pool and again after getting out of the pool. This will rinse the chlorine, saltwater, or other chemicals and contaminants from your hair and you can even use a special shampoo after you swim that is formulated to remove chlorine from your hair.

Comb gently

Since wet hair tends to tangle pretty easily and brushing your wet hair can be damaging on its own, use a wide-toothed comb to detangle and comb through your wet hair.
