Quick answer
A bathroom sink clogs when hair, toothpaste and soap scum collect on the stopper and in the pipe just below it. Pull the stopper, clean off the gunk and flush with hot tap water. Then put a small hair catcher in the drain, so the hair that starts most clogs never gets past the opening. Skip repeated chemical cleaners.
Free fix vs. permanent fix
Pull the stopper and clean it out
- Lift out the pop-up stopper and wipe off the hair and slime
- Pull what you can reach from the drain with gloved fingers or a barbed strip
- Flush with hot tap water for a minute or two
- Skip boiling water, which can soften plastic pipe joints
How long it lasts: A few weeks to a few months. Hair keeps washing in, so the buildup starts again.
A bathroom sink drain hair catcher
Many bathroom sink clogs begin as hair wrapped around the stopper crossbar, then a film of toothpaste and soap that holds everything else. A catcher keeps the hair out of the pipe, so there is nothing for the film to bind. Cleaning clears today's clog, and the catcher stops the next one.
What to get: Bathroom sink drain hair catcher
How long it lasts: Years. You rinse it every week or two and the pipe stays clear.

Why it happens
Hair snagging on the stopper
Many pop-up stoppers have a crossbar or a pivot rod just under the opening. Hair wraps around it and holds on to everything else that comes down: toothpaste, soap and skin flakes.
Soap and toothpaste acting as glue
Bar soap, toothpaste and shaving residue leave a sticky film on the pipe wall. Hair and flakes stick to that film and pack into a slimy plug. Hard water makes the film thicker.
A trap that slows everything down
The curved trap under the sink holds water on purpose, to block sewer gas. Debris slows down in that bend and settles, so the narrowing often starts there.
A small clog that was never fully cleared
Water drains a little slower, so you pour in a cleaner or run hot water and move on. The leftover mass keeps catching new hair, and the clog returns faster each time.

Do these in order, starting with the simplest.
-
Remove the stopper and wipe it clean
Tool used: Rubber glovesMany stoppers lift straight out after a quarter turn. If yours is held by a pivot rod, put a bowl under the pipe, loosen the nut on the back of the drain pipe by hand, slide the rod out and lift the stopper. Pull off the hair and slime with gloves on.
-
Scrub the opening
Tool used: Old toothbrushUse an old toothbrush on the stopper and the inside rim of the drain, where the film builds up. A few seconds of scrubbing removes what holds the hair in place.
-
Run a barbed strip down the drain
Tool used: Barbed plastic drain stripPush the strip in as far as it goes, twist it and pull it out slowly. Hair comes up on the barbs. Repeat until it comes up clean. Do not force it past a bend.

-
Flush with hot tap water
Run the hot tap for a minute or two. Do not pour boiling water down the drain. It can soften PVC joints and crack porcelain.
-
Fit a catcher and rinse it every week or two
Tool used: Bathroom sink drain hair catcherSet the catcher in the opening, or swap in a stopper that has a basket built in. Rinse it under the tap when you see hair or when water starts to pool. Wipe the rim of the drain each time.

When free fixes aren't enough
If the strip comes up clean but the sink still drains slowly, the buildup is lower, in the trap. Put a bucket under it, unscrew the slip nuts by hand, empty and rinse the trap, then put it back and check for drips. If the tub, shower or toilet is slow too, the pipes gurgle, or you smell sewage, the problem is in the main line, so call a plumber. And if you are clearing this sink every month or two, you are rebuilding the same plug each time. That is the case for a catcher. It costs little and takes hair out of the equation.

Bathroom sink drain hair catcher
Fixes: hair and debris getting past the opening and into the pipe
Look for: A size that matches your drain opening, so measure it first; Holes fine enough to stop hair but wide enough to let water through; Stainless steel or soft silicone that rinses clean; A shape that lifts out without you touching the hair.
- Who it's for
- Anyone who shaves at the sink, has long hair or shares a bathroom with others.
- Honest downside
- Your stopper has to sit where the catcher goes and you cannot remove it. Check the section below first.
Barbed plastic drain cleaning strips
Fixes: an existing hair clog you can reach by hand

- Who it's for
- Anyone with a slow sink right now who wants to avoid chemicals.
- Honest downside
- The strip comes up clean but the sink stays slow. The clog is lower down, so clean the trap or call a plumber.
Pop-up sink stopper with a removable hair basket
Fixes: hair clogs on sinks where you also need to hold water
Look for: A size that fits your drain opening, so check the listing; A basket that lifts out for emptying; A seal that holds water when you want to fill the basin.
- Who it's for

Which sink drain do you have? The catcher has to match
- Open hole or grid, no stopper: a drop-in strainer or a flat mesh cover sits right in the opening.
- Pop-up stopper you can lift out: take it out and use a catcher in the opening, or swap it for a stopper with a basket built in.
- Push-to-seal stopper: twist off the cap and use a push-type stopper with a removable basket made for this style.
Measure the opening across before you order, and check the size in the listing.
Habits that keep the sink clear
Wipe stray hairs into a tissue instead of rinsing them down. Rinse the basin with hot water after shaving. Wipe the film from the rim of the drain once a week. Rinse the catcher before it is full, not after the sink has started to back up.
What to skip
Repeated chemical drain cleaners
Strong liquid cleaners often burn a channel through a hair clog and leave the rest behind. They can also be hard on older fittings. If one does not work, do not add a second product or reach into the drain. The caustic water that is left is dangerous to splash, and a plumber needs to know it is there.
