The soap bars Kathy Mack sells are really nice, I use them on my body too. I also like the J.R. Liggett shampoo bar, which I can buy locally for around $7 at Wholefoods and other health food type stores.

The Chagrin Valley shampoo & soap bars left my hair feeling waxy and coated, even with using a vinegar rinse. I haven't experienced that problem with other soap/shampoo bars.
