I have tried industrial grade boric acid directly on scalp, and felt an immediate effect. Whether it is the mites or something else, this stops them in their track.
Another thing I noticed was my scal relaxed, and the slight but permanent inflammation in the prostate was relieved. This is a very important developement.

It suggests that there is some sort of chemical factor which controls specific smooth muscle contraction. Since the scalp is a muscle in this group, it is evident that prostaglandins are being secreted by these things. It makes sense though, they feed on endocrine, and other hormones. This may enable them to manufacture human-like hormonal products for their own use. This may also tie-in to the nitate\nitrite levels in saliva.

Since the hair tissues are rich in mast cells, this would be the ideal place to aggitate small blood vessles and feed off products moving through blood.

I think we're on to something very huge here. {at least for me} Shroom
