I have it very mildly on my scalp. And I have signs of it on my ankles and around my knees. The scalp gets a little itchy some times but it I leave it alone it seems to be OK.

Mine seems to come and go and I don't use any medication. I try to get plenty of rest and to eat well.

My mother had it worse than I and I wonder if it is not hereditary. Hope you find something that works for you . I realise that medication is sometimes necessary.
