Re: Post by Brendan from Adelaide, South Australia- Neither ACV nor baking soda worked for me, but when my scalp psoriasis was noticeably better after a week at the beach, I began using pure castile soap to clean my scalp and then rinsed it with a small amount of sea salt dissolved in warm water. Saline solution does sting a bit at first, but I decided to rinse it from my scalp only. My existing sores healed quickly - and without the excessive itching that had kept me constantly digging at my scalp. (I preferred sores to the constant itch! ) I've experienced 95% improvement after three months of this regimen and will likely fare much better when I finally conquer the learned scratching habit. I pray that this information will help others who found no relief from the many other remedies suggested, because psoriasis has such a negative effect on the quality of one's life. Best wishes!
