I too use shampoo bars pretty regularly and have not had a problem. I used to do ACV rinses and do them now, sometimes, but not every time I use a 'poo bar. At the moment, I am using Auromere's Tulsi-Neem soap bar for shampoo (my scalp needs the herbal treatment badly) and have not felt that need for the rinse like I have with other bars.

I am highly porous, I color my hair with high lift color regularly.
