Removing hair from a bathtub drain is a task that can usually be handled with common household items or inexpensive specialized tools. Hair combines with soap scum to form stubborn clogs, but several manual and natural methods can clear them effectively. 1. Manual Extraction (Direct Removal)
Set your shop vac to "wet" mode (remove the filter). Create a tight seal over the drain using a rag or duct tape around the hose. Turn it on. The suction can sometimes pull a hair clog back out whole. This works best if the clog is within 2 feet of the drain.
If you have a Shop-Vac (a vacuum designed for water), this can save you from taking pipes apart.
Solving the problem requires understanding one key fact: It doesn't dissolve easily in water or mild soap. Therefore, mechanical removal (pulling it out) is almost always superior to dissolving it (chemicals).
