Every shower drain in a household with long hair is fighting a slow, losing battle — hair binds with soap scum into felt-like mats that no amount of hot water dissolves. The fix is mechanical, cheap, and different depending on which drain assembly you're looking down at. Here's the complete field guide.

Know your drain, pick your tool
Open grid drain (visible crosshairs): the easiest — a zip strip goes straight down and comes back with the archaeology. Pop-up stopper (tub): the linkage behind the overflow plate is where hair accumulates; remove the two overflow screws and draw the linkage out slowly — the mat rides with it. Lift-and-turn or push stoppers (showers): unscrew the stopper (usually counterclockwise or a set screw), exposing the crossbar hair loves. Drum traps in vintage tubs: stop — these don't tolerate improvised snaking; the access is the drum's lid, and it's a careful job.
The technique that gets it all
Whatever the tool — zip strip, bent wire, small hook — the motion is slow withdrawal, not fast yanks: hair mats tear, and torn halves retreat down the line. Follow extraction with genuinely hot (not boiling, protect PVC) water and dish soap to move residual scum. If flow improves but isn't right, repeat — mats layer, and the second pass often finds the older stratum. A wet/dry vacuum sealed over the drain can pull stubborn mats upward when hooks fail.
If the clog is past your reach
A shower that stays slow after thorough stopper-and-crossbar cleaning has hair further down — often at the trap below the floor or the branch line junction. Tub-shower combos add the possibility that the blockage sits where tub and shower lines meet. This is hand-auger or professional-cable territory; chemicals will not dissolve a mature hair mat (marketing notwithstanding) and old drains deserve gentler methods than heroic plunging.
Ending the cycle permanently
One accessory changes everything: a silicone or stainless hair-catcher over or in the drain, emptied after showers. Households that install one essentially exit the shower-clog business — we say this knowing it costs us service calls. Pair it with a monthly hot-water-and-enzyme rinse and the drain stays clean indefinitely. For drains with years of accumulation and chronic slowness even after cleaning, one professional cable pass resets the line to bare walls, and the catcher keeps it there.
