As mentioned above, I use J. R. Liggett's shampoo bar, which can be found in some health food stores. It's really just a mild soap with some oils mixed in. I'm currently using VO5 conditioner (to help with detangling), which is very inexpensive, and silicone-free. Suave has the Naturals line of conditioners, which is also inexpensive and silicone-free (but the Naturals shampoo is NOT sulfate-free). Some folks skip the shampoo and wash with the silicone-free conditioner.
