FOUND SOMETHING WORKING FOR 2 DAYS SO FAR. I was going crazy with an itchy scalp, no dandruff. I do have rosacea. This is what I tried. Dandruff shampoos of every brand, tea tree products, vinegar & water mixture which gives some relief all day (I pour a cup over my head after shampooing, takes out all product residue), changing hair care products numerous times, unscented products......you name it and I have tried it. What has worked for 2 days so far is this: I took 2 boric acid capsules and dissolved them in water, poured it over my head and DID NOT rinse. ITCHING IS GONE!
