yo i have dandruff and the shampoos dont really work i tryed head and shoulders but that only works when it wants to. i tried selsun and it work when i used it but it kept getting in my eyes. so what i suggest is try the vinager thing out i am this weekend. And as for oils my sister in law put a oil in my head called "Dr. Hobbs" I think she got it from a convience store. but if you can find it massge it into your hair an hour after you wash you hair. Also the mayo thing worked for my aunt. She let it set in her hair for about an hour. Just try one of my techniques. see u later
