- QUESTION: I have been diagnosed as having seborrheic dermatitis. I am using
- a medicated shampoo every fourth day. It holds the itching in check, but I
- would like to have a cure, if that is possible. Also would like to know how
- it got started and if it is contagious, and how to get rid of it? Everyone
- seems to think it is a lifetime guest. I would very much appreciate your
- explanation.

- ANSWER: It sounds like you have a mild case, one which only affects the
- scalp, rather than other parts of your body. It is the dry or greasy scales
- of the scalp caused by seborrhea that create those embarrassing flakes we call
- dandruff. However, in severe cases the lesions can appear behind the ears, in
- the ear, on the eyebrows, the bridge of the nose and even on the chest. In
- newborns, seborrheic dermatitis is often seen, and is called "cradle cap".
- The good news is that it does not cause hair loss. The less happy news is
- that it may indeed be a lifetime guest.
- However, it may be completely controlled through the proper use of
- medicated shampoos. Various medications are effective, including zinc
- pyrithione, selenium sulfide, sulfur and salicylic acid, and preparations
- containing coal tar. In severe cases that require a more rapid response,
- hydrocortisone or other corticosteroid lotions can be employed. Although
- these preparations are used as frequently as once or twice a day to begin
- with, once the condition begins to subside applications can be reduced to once
- or twice a week. Shampoos are also used on a daily basis to begin treatment,
- and after reducing the inflammation can usually control the dandruff, scaling
- and itching with but one or two applications per week. Though not cured, the
- condition may disappear for months at a time (remission). Genetic factors are
- thought to be a main element in the cause of the condition, but climate also
- plays an important role, as the situation worsens during the winter months.
- Though not considered an infectious disease, some recent research has focused
- on a common yeast (Pityrosporum ovale) as a possible cause, and the use of
- topical anti-yeast medications can be effective in some patients.
