Something else you can try is toilet bowl cleaner (the foam).. it contains a pretty strong alkaline (sodium hydroxide) wich WILL destroy hair..but is must be 'in contact' with the hair for a while (couple hours).. hence use the spray foam bowl cleaner. CAUTION.. watch out for your eyes. Oh.. If you have a fiberglass tub, protect it in some way as the alkaline chemical will take the shine off of the tub.
