Hello, my name is Amy. My husband has been plagued with acne since a child, he is now 41. The last year and a half he had this one bad spot on the back of his head in his hairline that kept flaring up and then more popped up and he began pouring hydrogen peroxide on them. When the peroxide hit these sores small worm like things came pushing out. He removed them and placed them on slides and we looked at them through a microscope and found they were demodex mites. This was 4 days ago. He has began a regiment of natural holistic items that include tea tree oil, Borax, Yellow Sulphur, Apple cider vinegar, and so on...He goes to see his dermatologist on Friday. My question to you is how contagious is this condition. I know they like to latch on to hair follicles and feed off subaceous oils but I don't think I have them. how can I tell without going to the doctor as well. i have no sores, no scalp or facial irritation.
