Wow thankyou for sharing this! I have pink Himalayan rock salt would that work? How much would you suggest putting on? And should I use a shampoo with it or not and if and when it clears it completely should I continue to use it or use an organic paraben and sulfate free shampoo that I have already? I've also found a few other things I'm going to try that I definitely suggest trying. The information I have gotten from three different people who now say they are cured completely. Firstly is using alcohol (grain not rubbing) vodka in particular apparently completely kills the bacteria they have been cured for 3 years now. Second person has been cured for several months after taking biotin they believe SD is related to a deficiency of certain nutrients such as biotin. Third person says it's due to problems with the gut and have cured theirs from taking VSL#3 supplements on amazon they have it the cheapest (take half a sachet up to 1 a day) and that's it. I strongly believe it's something to do with the liver gut and immune system.
