Well folks, I spoke too soon about those shampoo bars. The first week went really well, then things went downhill. My hair was taking longer to dry and starting to feel gross, the sure signs of build-up. I got out my trusty baking soda and scrubbed my guts out, but I swear it made it worse. I have always used baking soda for build-up, be it chlorine from swimming or hairspray. I swear in this instance, it just gave the guk something better to stick to. This weekend, it was so bad that I took my aunt's advice and washed my hair with dawn dish detergent to get it out. So...more shampoo fail and back to buying it.
