turned my hair dull brown gray [SEP] this does not work if you have well water everything i read said that this would just be a conditioning treatment but this turned my hair a dingy brownish gray it was awful having read more online about cassia treatments i have learned that you cannot use this with well water or water buildup this should be on the packaging in large printi guess it should work fine if you have done a clarifying treatment recently and you are using distilled water but who would think to do all that probably smarter people than i well you have been warned
