Thanks, Wavy_Girl! The Bobeam bars look nice, especially the shealoe. She does recommend following with a conditioner, though.

I thought the ACV rinse was to remove mineral build up. If its used to balance the ph, would I be able to use a ph-balanced shampoo bar without following with an acid rinse?

As this article notes, it is impossible to make a pH balanced shampoo bar.

If you do not have hard water (i.e., high mineral calcium content), you may be able to skip the rinse.

I use the bars 3-4 times/week, and ACV once a week. My biggest concern with the vinegar was the odor, so I made an infusion with herbal teas from CV - smelled awesome and left my hair super shiny. Others have recommended lemon and/or orange rinds and hibiscus leaves (h/t Keihs), I haven't tried those yet but they'll be in my next ACV.
