Sorry to read this. Same thing is known to happen to susceptible individuals with sulphate surfactant shampoos, experts believe that is due to inflammation at the follicular level and I do wonder if you are experiencing a similar effect as you admit to being rather enthusiastic. Of the people I have read about experiencing this phenomena, a good number have pre-existing scalp and/ or other inflammatory health conditions.
