You’ve put a lot of work into your hair, and it's totally understandable that you don’t want to ruin it with chlorine and saltwater. Swimming is a great way to exercise and enjoy time outside with friends, but you shouldn’t have to sacrifice having healthy, beautiful hair. We’ve put together a list of 11 things you can do before, during, and after swimming to keep your hair drier and damage-free.

1

Put your hair up.

Wear your hair in a high bun to keep loose strands out of the water. Putting your hair up also makes it easier to wear a swim cap so you can really keep water out. If you have natural Afro-textured hair, you can also opt for flat twists or bantu knots.^{[1]XResearch source}
- Try out a braided bun, a ballerina bun, or a topknot to keep your hair away from the water.
- A regular braid, french braid, or fishtail braid will help keep your hair tangle free, but those hairstyles might not keep your hair dry.

2

Choose a silicone swim cap.

Silicone caps are more waterproof than latex/rubber or lycra options. They’re made of a thick material and offer a tight seal. A properly fitting cap will keep your hair significantly drier than if you don’t wear a cap, but some water still might seep through.
- You can even double up on swim caps, as long as it doesn’t feel tight or uncomfortable!
- Try putting a latex/rubber cap under a silicone cap. Slip your goggles strap in between the two layers to keep them in place.^{[2]XResearch source}

Wear a shower cap under a swim cap.

Slip a shower cap under a silicone cap for an extra waterproof barrier. Shower caps aren’t made to be submerged on their own since they’ll slip off, but the silicone cap will keep it in place. Just don’t try using a shower cap without another cap on top!
- Use a new shower cap so that the elastic isn’t stretched out.

Wear a waterproof headband.

Silicone headbands go over your ears and forehead to make sure no water can seep into your cap. If you don’t want to wear a cap, try any waterproof headband on its own. A headband can help keep your hairstyle in place so you won’t have to worry about loose strands getting wet.^{[3]XResearch source}

Rinse your hair immediately after swimming.
