How to Put On a Swim Cap

Six steps. The order matters more than the technique.

How we pick

The short answer

Wet the hair first, turn the cap inside out and hold it open with both hands, place the front edge at the hairline, then draw the cap back over the crown in one motion. Tuck stray hair up under the edge with a finger rather than stretching the cap over it.

The six steps

  1. Wet the hair. Dry hair has more friction and more static. This single step removes most of the pulling, and it also means the hair absorbs fresh water before it absorbs chlorinated water.
  2. Gather the hair low and loose. A low ponytail or a loose twist at the nape. A high bun makes a lump that pushes the cap off the back of the head.
  3. Turn the cap inside out and hold it open with both hands, thumbs inside near the front edge, fingers on the outside.
  4. Place the front edge at the hairline first, just above the forehead, and hold it there.
  5. Draw the cap back over the crown to the nape in one smooth motion. Do not stretch it forward over the face.
  6. Tuck stray hair up under the edge with a fingertip. Do not pull the cap down over loose hair — that is where the pulling comes from.

The long-hair method

With hair past the shoulders the aim is to get the hair inside the cap before the cap is fully seated, rather than tucking it afterwards.

  1. Wet the hair and gather it into a low, loose ponytail or a loose braid.
  2. Hold the cap open and place the front edge at the hairline as normal.
  3. Draw the cap back only as far as the crown, so the back is still open.
  4. Feed the ponytail up into the open back of the cap with the other hand.
  5. Now draw the rear edge down to the nape, over the hair rather than against it.
  6. If the cap is asymmetric, check the extra volume is at the back before letting go.

If this still feels like a fight, the cap does not have enough volume — see best swim caps for long hair. Technique compensates for a marginal cap; it cannot compensate for a cap with no room in it.

Putting a cap on a child

The two-person method is genuinely easier and worth doing while a child learns. One adult holds the cap open at the front and back with both hands, the child leans forward and places the crown of their head into the opening, and the adult draws the cap back to the nape.

Leaning forward is the part that matters. It puts the crown into the cap first and lets gravity keep the hair back and out of the way, which is the opposite of what happens when a child stands up straight and the cap is dragged down over their face.

Teach the removal technique early, because a child pulling a cap off with a nail will tear it. Flat fingers under the front edge, push back, lift it off. And if the child genuinely dislikes silicone, a lycra cap is much gentler and still does the containment job — see best kids' swim caps.

Putting a cap on over ear plugs

If someone is wearing ear plugs — which is the actual tool for keeping water out of the ear canal, not the cap — the order matters. Plugs first, cap second, and the cap edge should pass over the plugs rather than catching under them.

  1. Seat the plugs properly in the canal, not resting in the outer ear.
  2. Put the cap on front-edge-first as normal, keeping the rear edge high until the crown is covered.
  3. Draw the rear edge down over the ears in one movement rather than tugging it across them.
  4. Run a finger around the ear on each side and check the plug has not been levered out of position.

A low-profile plug is worth choosing for exactly this reason: a tall stem catches on the cap edge and gets pulled out as the cap goes on. Full comparison in swim cap vs ear plugs.

The five mistakes that cause most of the trouble

  • Dry hair. More friction, more static, more pulling. Wetting it takes five seconds and removes most of the problem.
  • Stretching the cap forward over the face. It should go on from the hairline backwards. Pulling it down over the forehead drags hair with it.
  • A high bun. It makes a hard lump that pushes the crown up and lifts the rear edge off the nape. Low and loose is what works.
  • Fingernails under the edge. The single most common cause of a torn silicone cap, both putting it on and taking it off.
  • An asymmetric cap on backwards. The extra volume is at the back for a reason, and reversed it does nothing at all.

Taking it off, and looking after it

  1. Slide flat fingers under the front edge at the hairline.
  2. Push the cap back and up off the crown. Do not peel it forward over the face.
  3. Rinse it in fresh water — chlorine and lake water both shorten a cap's life.
  4. Turn it inside out and dry it over something round: a bottle, a jar, your fist.
  5. Store it flat rather than balled up. Creases set, and set creases are where a cap splits.

What we recommend

Wet hair, cap inside out, front edge first, flat fingers. That is the whole technique and it works on every material. If a cap still pulls after that, the problem is the cap: either latex, which pulls by nature, or a standard dome on hair that needs volume.

One small thing that helps more than it should: own two caps. A dry cap goes on far more easily than a damp one, and a damp cap that has been balled up in a bag is the worst case of all.

Our picks

Technique compensates for a marginal cap and cannot compensate for a wrong one. The elastomeric cap stretches furthest so it goes on with least force; the long-hair cap is the answer if the fight is about volume; the lycra cap is the one to try if someone has given up on silicone entirely.

Speedo Elastomeric Silicone Cap

A thicker, stretchier silicone than the standard cap — easier to pull on and slower to tear.

Specifications

Material
Elastomeric silicone
Fit
One size, adult
Hair length
Short to medium
Seal
Smooth interior

What works

  • Stretches further than standard silicone, so pulling it on does not feel like a wrestling match
  • Thicker walls resist the fingernail tears that kill most caps
  • Keeps a low profile, so it works for lap swimming
  • Holds warmth usefully in cool lake water

What doesn’t

  • No room for long hair at all
  • Thicker silicone is warmer than most people want in a heated pool

Who it’s for

An adult with short or medium hair swimming laps who is tired of replacing torn caps.

Bottom line

The durable everyday adult cap. Long hair needs a long-hair cap, not a thicker standard one.

2. Also goodTYR

TYR Long Hair Wrinkle-Free Silicone Cap

An asymmetric cap with extra volume at the back, which is the only design that takes a bun without squeezing.

Specifications

Material
Silicone
Shape
Asymmetric, extra rear volume
Hair length
Long, braided, locs
Finish
Wrinkle-free

What works

  • The extra rear volume is real, not marketing — a ponytail or bun goes in without dragging hair forward
  • Silicone does not catch and tear hair the way latex does
  • Wrinkle-free molding means fewer creases to leak at
  • Holds its shape across a season rather than going slack

What doesn’t

  • The asymmetric shape is easy to put on backwards, which undoes the whole point
  • Warmer than lycra, which is noticeable in a heated pool

Who it’s for

Anyone with hair past the shoulders, braids, locs, or volume that a standard cap crushes.

Bottom line

The long-hair default. If a standard cap has ever given you a headache, this is the fix.

3. Also goodSpeedo

Speedo Lycra Swim Cap

The most comfortable cap you can buy and the least waterproof — a hair-keeper, not a water-blocker.

Specifications

Material
Lycra / polyester blend
Fit
Soft, stretchy
Water resistance
Minimal
Hair length
Any, including long

What works

  • No pulling, no snagging, no pressure — it feels like a fabric hat
  • Fits long hair without a specialist shape
  • Comfortable for an hour or more in open water
  • Sun protection for the scalp on a bright lake day

What doesn’t

  • Does not keep hair meaningfully dry — water passes straight through
  • Fabric stretches out over a season and stops gripping

Who it’s for

Someone who wants hair kept out of their face and off their goggle strap, and does not care about dryness.

Bottom line

The right cap if the goal is comfort or keeping hair contained. The wrong cap if the goal is dry hair.

Questions

Frequently asked questions

How do you put on a swim cap with long hair?

Wet the hair, gather it low and loose, place the cap's front edge at the hairline and draw it back only to the crown. Then feed the ponytail up into the still-open back of the cap and draw the rear edge down to the nape over the hair.

Why does my swim cap pull my hair?

Usually dry hair, a latex cap, or pulling the cap down over loose hair instead of tucking the hair up under the edge. Wet the hair, switch to silicone, and tuck rather than stretch.

Should you wet your hair before a swim cap?

Yes. It reduces friction so the cap goes on with less pulling, and hair that has already absorbed fresh water takes up less chlorinated water in the pool.

How do you put a swim cap on a toddler?

Two people is easier: one holds the cap open front and back, the child leans forward and puts the crown of their head into the opening, and the cap is drawn back to the nape. Leaning forward keeps the hair out of the way.
