6% sulfur cream kills demodex mites, get ur pharmacy to make it up, 6% sulfur in aqueous cream. (Aqueous is the cream base). Its cheap.
Put it on ur face just before it gets dark & leave it on all night every night. Use it on ur face or eye brows, Ur eye brows will grow back just like mine did.
Buy sulfur powder & mix it in with ur shampoo, use around a level teaspoon mix with the usual amount u use per wash (use a cup add a level teaspoon then add abit of shampoo & stir add a tad of hot water & stir). Lather on ur scalp & leave for 15-30 minutes then wash out ( only do this when its dark, lights off! Shorter the hair the better.) Even use as a face soap, leave on for a few minutes.
"Face doctor" soap & cream also kills demodex mites, use the cream/soap at night & that does the trick.
