I also have fine, thin hair so I can't spare much either : ) I also use the CV bars, but many people with our hair type don't react well to shea and/or castor oil. I have to watch shea content or my hair goes berserk (that's what Bobeam did to me, as did the CV formulas with shea high up in the ingredients). Your experience with the Shea Moisture Y&B suggests that shea is not your hair's friend, either. I use that line, but only in moderation (no more than 2x/wk).
There are several poo bar manufacturers that don't use shea butter or castor oil. I haven't tried them yet, but if you do a search for "shampoo bars" there are several threads with great recommendations. I'll post a few links when I get back to my laptop.
The bars are definitely not for everyone, so if you find that other products work better, don't feel guilty! Just do what's right for YOU.
