A lot of Black women don't swim because of their hair. That's a real thing that happens, and it shouldn't. Swimming is good for your body and your mind. The hair situation is manageable with a routine that takes maybe ten minutes before and after getting in the water.
What Chlorine and Salt Water Do
Chlorine strips the hair of its natural oils and disrupts the cuticle, leaving it rough, dry, and prone to tangling. With repeated exposure and no protective measures, it can bleach the hair slightly and cause significant dryness that compounds over a swimming season.
Salt water works differently: it draws moisture out of the hair shaft through osmosis and leaves mineral residue on the strands. It also causes significant tangling, particularly in 4B and 4C hair, because the salt crystals get into the coil structure and create friction between strands.
Before You Get In: The Pre-Swim Routine
Saturate your hair with fresh water before entering the pool or ocean. Hair that's already wet absorbs less pool water or salt water because the strands are already full. Apply a thick, creamy leave-in conditioner or coconut oil through the length and ends. This creates a protective layer between your hair and the water chemistry.
Braid or twist your hair before swimming. Multiple large twists or braids keep the hair contained, reduce tangles, and minimize how much of each strand is exposed to the water. A swim cap over the twists adds another layer of protection if you're a lap swimmer.
After Swimming: The Post-Swim Routine
Rinse immediately after getting out of the water. Fresh water dilutes and removes chlorine and salt before they have time to set in and do more damage. Rinsing within five to ten minutes of swimming makes a real difference in how your hair feels after.
Follow with a clarifying or chelating shampoo to remove chlorine and mineral residue. Then deep condition. Post-swim deep conditioning is not optional. It rebuilds the moisture that the swim stripped away and keeps the hair from going into a prolonged dry spell.
For Regular Swimmers
If you swim multiple times a week, you'll need to build your wash day schedule around that. You don't need to do a full deep conditioning session after every swim. A quick rinse and light leave-in can carry you through between full wash days. But every five to seven days, do a clarifying wash and full deep conditioning session to reset the moisture and remove accumulated buildup.
