Prepare your hair for swimming
Before a pool or open-water swim, wet loose hair with fresh water and put it under a swim cap that has enough room. The cap keeps hair contained but is not guaranteed to keep it dry.

Step by step
STEP 1 OF 4Wet your hair with fresh water
- Remove clips, pins and sharp jewelry. Place the open swim cap within reach, with a soft hair tie on your wrist if the gather may need a temporary hold.
- Under a shower or tap, wet the crown, sides, nape and lengths with fresh water.
- Lift loose hair with one hand so water reaches underneath. You do not need a pre-swim product for this method.
STEP 2 OF 4Make a broad, loose shape
- Bring longer hair up toward the crown with both hands, keeping the roots relaxed.
- Fold or coil the lengths broadly against the head instead of making a tight knot or a bulky bump at the nape.
- If the hair will not stay while you reach for the cap, use one relaxed pass of a soft tie. If it still will not fit, choose a cap with more room rather than forcing it.
STEP 3 OF 4Put on the cap and check the fit
- Place both hands inside the opening and stretch it wide enough to clear the gathered hair.
- Set the front edge at your hairline, then guide the cap back and down with your finger pads.
- Smooth the edges and tuck only reachable loose strands. The cap should stay in place without painful pressure, root pulling or a headache.
STEP 4 OF 4Ease the cap off after the swim
- Once you are out of the water, lift a reachable lower edge away from the hair with your finger pads.
- Use both hands to raise the opening up and clear of the hair without dragging it. Free any caught strands instead of pulling.
- Release the hair and remove any temporary tie, then rinse your hair promptly with fresh water. Rinse the cap as directed; let it dry before storing it.
About 3–6 min hands-on for fresh-water wetting, loosely gathering, fitting the cap, then removing it and rinsing after the swim. The swim, cap drying and later shampoo-and-condition wash are separate.
You’re done when…
Before the swim, wet hair sits inside a cap that stays in place without painful pressure or pulling. After the swim, the cap and any temporary tie are removed without yanking, and the hair is ready for a fresh-water rinse.
