Kathymack, from your sig I can see you've been using them a while! Have you seen more or less frizz with them (and a rinse out)? And do you use "chelating" or moisturizing ones?
Yossarian, I'm going to look for this thread.
It sounds like shampoo bars aren't as moisturizing even without the chelating ingredients? Regardless, I think I might try some samples, because that coffee one sounds DELICIOUS. (I have dark brown hair, so I'm not worried about tinting) Thank you for the information; very useful!
