text: scalp odor? my 6 year old daughter has scalp odor no matter how much i wash and wash her hair. i have heard to use some kinds of soap or something but i don't remember exactly. could anyone out there tell me what would be best to use to cure this problem? maybe her hair follicles have a bacteria or something.  has she been checked out by a doctor?  there has to be an underlying cause of the smell, and smells are often due to some type of infection.
