Let’s dive in (pun intended). Before we fix the problem, let’s understand it. Hair doesn't just float down the drain. It binds. Wet hair is sticky. As it travels down the pipe, it catches on crossbars, drain stoppers, and built-up soap scum (that waxy residue from bar soap). Once a few strands get stuck, more hair sticks to it. Then, the soap and minerals from hard water glue it all together into a slimy, rope-like monster called a "drain snake."

Push the snake down again. You usually need 3–4 passes to get the "core" of the clog and the satellite strands.

Standing in two inches of soapy water by the end of your shower is a special kind of morning frustration.
