Remove a Hair Clog from Your Bathroom Sink Drain

Hair clogs are the most common bathroom drain problem, and they're almost always fixable without calling a plumber. The hair tangles with soap residue and debris just below the stopper or a few inches down the pipe, restricting water flow until the drain backs up entirely. The good news: you can clear it yourself with tools you already own. The key is knowing which method fits your clog depth—surface hair needs one approach, deeper tangles need another. Done well, you'll have water flowing freely again in under an hour, and you'll understand how to prevent the next one.

1. Remove Hair at the Source. Open the cabinet and look at the underside of your sink. Locate the stopper linkage—usually a horizontal rod connected to the stopper assembly. Unscrew the nut holding the rod to the tailpiece, then pull the rod out. The stopper should lift right out of the drain. Reach down with your fingers or needle-nose pliers and grab any hair wound around the stopper stem. Pull it out in one clump if possible. Rinse the stopper under hot water to clear soap film, then set it aside.
2. Test Before You Proceed. Fill the sink halfway with hot water. Let it drain on its own. If water flows normally now, your clog is cleared and you can reinstall the stopper. If water drains slowly or backs up, proceed to the next step.
3. Plunge the Tangle Out. If the drain still moves slowly, fill the sink with 4 to 6 inches of water. Place a cup plunger over the drain hole, making sure it seals completely around the rim. Block the overflow hole with your other hand if one exists (on some double-basin sinks, block the other drain). Push down and pull up rapidly 10 to 15 times, keeping the seal tight. Remove the plunger and let the water drain. Repeat 2 to 3 times if needed.
4. Snake the Deep Clog. If plunging didn't work, get a hand-crank drain snake (also called a plumbing auger). Feed the coiled end down the drain, keeping a hand on the crank to feel resistance. When you feel the clog, stop pushing and begin turning the crank slowly. The rotating head will either break up the clog or wrap hair around its tip. Turn 10 to 15 rotations, then pull the snake out slowly. If you hooked hair, expect a bundle of it wound around the tip. Repeat until water flows freely.
5. Improvise With What You Have. If you don't have a snake, unbend a wire coat hanger and form a small hook at one end, leaving about 6 inches of hook. Feed it down the drain slowly, feeling for resistance. When you hit the clog, twist gently and pull upward. You're aiming to snag the hair bundle, not break it apart. It may take 3 to 4 tries. Pull out whatever comes up, then run hot water to flush debris.
6. Access the Trap Directly. If snaking doesn't work, the clog is likely deep in the P-trap or main drain line. Place a bucket under the P-trap (the U-shaped pipe under the sink). Using an adjustable wrench, loosen the slip nut on both ends of the trap. Unscrew by hand and lift the trap away from the drain line. Pour out any standing water and debris into the bucket. Look inside the trap with a flashlight—there's usually a hair mass stuck at the lowest point. Use needle-nose pliers or a straightened wire to pull it out. Rinse the trap under the faucet.
7. Don't Miss Hidden Debris. While the trap is off, look up into the drain opening and the bottom of the tailpiece (the straight pipe the trap was connected to). Feed a wire hook or small brush up into the tailpiece to dislodge any hair stuck above the trap. Shine a flashlight in and pull out anything you see. Flush the opening with hot water from a pitcher to clear loose debris.
8. Reconnect With Care. Check that the rubber washers inside both slip nuts are in place (they should sit in a small groove on the nut). Position the trap back under the sink, aligning the outlet with the tailpiece and the inlet with the wall drain. Hand-tighten both slip nuts, then snug each with the wrench—firm but not crushing. Turn the wrench about a quarter turn after you feel resistance. Don't over-tighten or you'll crack the nut.
9. Verify the Fix Holds. Fill the sink and let it drain fully. Watch underneath the sink for drips at both slip nuts. If water drips, tighten the nut slightly more. If water flows freely and nothing leaks, you're done. Run hot water for 30 seconds to flush any remaining debris.
10. Restore the Stopper. Insert the stopper stem back into the drain opening. Reattach the linkage rod to the tailpiece, tightening the nut by hand. Adjust the rod so the stopper sinks fully when you close it and rises above the rim when you open it. If the stopper doesn't seal properly, loosen the nut slightly and reposition the rod.
11. Stop Hair Before It Clogs. Buy a simple mesh drain catch (strainer basket) that fits your sink opening. Drop it into the drain—it floats on the stopper and catches hair before it enters the pipe. Empty it weekly by lifting it out and rinsing hair into the trash. This single step cuts future clogs by 80%.
