Myself and two daughters have very long hair, brushing our hair at the sink is not a good thing! Roto - Rooter was great at fixing the nasty clog all our hair had created. It took an hour or two, and the plumber was very sweet and joked around with my husband about all his women and their long hair! And no wonder we had an extremly slow draining sink! The clog we had going with all the hair could have made a small kitten!
