Neem oil to the rescue
Well, I am a true testimonial! I have only been using neem seed oil for a short time, since Thursday evening last, and already I notice a big difference. I was exposed to water from a deteriorating water heater carrying well water and the gentleman in whose home I was house sitting had red bumps all over his skin when I met him about a month after I moved in (he was in a nursing home) And by then I was already scratching and showering elsewhere. My scalp has been riddled with parasites and I have used wild oregano oil, internally and externally, and tea tree oil, but still my scalp crawls...
With the neem seed oil, I still get a bit of it, but not half what it was.
I will let you know one I've gotten over this horrible problem. Neem to the rescue!
