Appear to have found a cure!
Had what appeared as pustules in hair follicles on scalp (all over scalp but mainly towards front where touched head). Starts as red area then small pimple which grows. Itch often present.Have had condition for 18 years or so, after 3 years it spread to my chest hair. Some hair loss caused and much annoyance and discomfort.
Doctors prescried many Antibiotics and creams which worked only once for a limited period. Shampoos had no effect.
Have recently cut back on dairy products. Spots disappear when do not have dairy.
If I start having dairy again they start to reappear!
