We'd be surprised how many of us with itchy scalps have "somethin' goin' on" ... One of these posts links to photos of an Asian man undergoing surgery after years of eating Sushi (raw fish) with his scalp opened up and oodles of little worms in there! I have some itching in my right scalp, but it's much reduced since cleansing many months now. I suspect all the pingings in that area were the critters being killed. According to Dr C, we need to avoid solvents in our foods (anything with "Benzyl" or "Propyl"), as well as topicals such as IsoPropyl Alcohol (rubbing alcohol), since these render our tissues more porous, opening up channels for the tiny worm-stages to travel to other areas of the body. Use grain alcohol (vodka) instead, or even vinegar (I keep both in spray bottles around the house).
