To unclog a bathroom sink, physically remove the hair from the pop-up stopper and use a barbed drain tool or plunger to clear remaining debris.

Most bathroom sink clogs are caused by hair and soap scum accumulating on the pop-up stopper or in the P-trap. Start by removing and cleaning the stopper, as this often resolves the issue. If the clog persists, use a plastic barbed hair removal tool (or a wire hanger) to pull out debris. For deeper clogs, use a cup-style plunger while sealing the overflow hole with a wet rag to ensure proper suction. If these methods fail, remove and clean the P-trap under the sink. Avoid chemical drain cleaners, which can damage pipes and are often ineffective against hair. Prevent future clogs by using a drain hair catcher and cleaning the stopper regularly.
