I just looked it up, where I am currently living at may have moderately hard water, but thankfully the build up didn't happen this time (but I could be and might actually be wrong on this), and I am going to make absolutely sure I dilute bronners at least 10:1 if not 12:1 from here on out, just to be sure. I haven't done a deep clean for at least. I haven't deep cleaned my hair in about 4 months, I am thinking I may end up doing a deep clean maybe twice a year. Since that is better on my hair than what i had done before.
