My sister-in-law said she got urinary traction because of taking BUBBLE bath all the time. Because soap is alkaline in general, it knocks our body PH out of balance. Some people are susceptible to urinary traction, others not. So if you keep getting recurring problems, then you might stay away from taking a bath. But personally, I have never had a problem. Besides, soapnuts, shikakai and amla being more acidic, I don't know if it will cause much trouble.
