Bath tub drains slow, I think is hair problem. What is the best way to clear this?

You can get something called a Zip-It at Walmart for about $2.50. This is great for getting hair out of a drain. It's about 25" long and has little barbs along the side which catch the hair. Use this on any drain for hair clogs. I love mine! Don't bother with Liquid Plummer.

Zip it may work but tub drains frequently have rods that operate the plug, they may snag. If the Zip it doesn't work try mixing 1/2 cup of table salt with 1/2 cup baking soda and dump into the drain. Add a cup of vinegar and allow to soak over night, next day a big bucket of really hot water should clear the drain.
