Remove the lid to the shower drain, and reach down into the hole to pull out as much hair as you can reach. Turn on the water to see if it still backs up or not.
Position a plunger over the drain hole, making sure to cover the entire hole, and make a seal. Push straight down on the stick, and then pull up, using the pressure to pull hair and other items that are stuck further down the pipe. Alternate pushing and pulling several times, and move the plunger away to check the progress. Repeat this process several times.
Slide a drain claw into the drain as far as you can, and pull up to dislodge any hair or other material in the drain.
Pour a cup of baking soda down the drain, and pour in a cup of vinegar immediately afterward. Wait for the mixture to stop foaming, and then pour a gallon of hot water down the drain. Follow up with a chemical product if the clog is still present.
