If I were you I would start on Humaworm's parasite cleanse program -- using the humanatea (and cream) as well to "stir things up." I would also minimize using soaps and toothpaste, and try to minimize shampoo. I started using good gums toothpaste and my mouth is much cleaner. After using humaworm, my hair stays cleaner longer.
(Does anyone else notice that the conventional remedies that "they" recommend often cause the very thing they are supposed to fix??)
