I don't wash my hair in the bath, for the exact reason that you mentioned above to mooism. You rinse your hair in the water that is all soapy and it doesn't feel like you get all the soap out. I have a lot of hair, and it really doesn't work well. I just don't wash it when I take a bath. Baths are for relaxing, and showers are for cleaning. :-p But of course, I don't shampoo my hair every day anyway.
