I've developed what I think is dandruff. But it is most severe in my beard region of my face, cheeks and chin. I've tried pretty much every dandruff shampoo that is on the shelves I've also tried tea tree oil to no avail. At this point I'm just wondering if anyone has had similar problems and what might work that I haven't tried yet. It started a little over a year ago and I have been through a lot of stress and put on a bit of weight, is it possible that could be the cause? My last resort is to see dermatologist I guess.
