Hi Bondo - glad you found success with your hand sanitizer. I have scalp Psoriasis and have tried everything! I too have gone down the line that you tried - the re-creation of the ocean - I use a 100% seaweed powder from a company in Belfast - I have the treatments down to every 2 weeks now - bit messy, but they work for me.
I would love to try the hand sanitizer but I do get an allergic reaction to any hand wash (it plays havoc with the hand wash supplies in work!!) - and wonder what it would do to my scalp!?!
Having thought about it - I think the alcohol in the sanitizer would stop any build up of nasties and therefore allow sores to heal.
Well good luck and hopefully you have found ur cure and take care.
