You could try pouring a gallon of bleach (won't hurt the pipes) into the drain and letting it sit overnight. In the morning boil a pot of water and pour it down the drain, then turn on the tub water full hot and let it run for at least five minutes. If the clog is just hair/sludge this will usually dissolve it enough to flush it out, if the boiling hot water doesn't flow down the drain quickly then you have a bigger problem and should call a plumber.
