Seborrheic dermatitis is a condition that dermatologists frequently diagnose and treat.
If you think you might have seborrheic dermatitis, you should see a dermatologist for a diagnosis. This common skin condition can look like psoriasis, eczema, or an allergic reaction. Each of these skin diseases requires different treatment.
A dermatologist diagnoses seborrheic dermatitis by:
- Reviewing the patient’s medical history.
- Examining the patient’s skin and looking closely at the rash.
Sometimes seborrheic dermatitis is a sign of an underlying medical condition. If your dermatologist suspects this, medical tests may be necessary.
Although treatment cannot cure seborrheic dermatitis, treatment has benefits. Treatment can loosen and remove scale, prevent a skin infection, and reduce swelling and itch.
The type of treatment a dermatologist prescribes varies with age and where the seborrheic dermatitis appears on the skin.
Infants (scalp): Called cradle cap, this tends to completely disappear without treatment. If treatment is necessary, a dermatologist may recommend:
- Shampooing the baby’s scalp daily with a baby shampoo.
- Gently brushing away the scale, once scale starts to soften.
- Applying a medication to the infant’s scalp.
Infants (skin beyond the scalp): This, too, will clear. If treatment is needed, a dermatologist may prescribe a medicine that can be applied to the child’s skin.
Adolescents and adults (scalp and rest of body): After infancy, seborrheic dermatitis usually does not go away without treatment. For the best results, a dermatologist will consider many factors before creating a treatment plan. Treatment may include:
- Dandruff shampoos.
- Medicine to apply to the skin for short periods of time.
- Barrier-repair cream.
Dandruff shampoos can be helpful on the skin as well as the scalp. Your dermatologist can explain how to use these shampoos on the skin.
Often the best results come from combining two or more treatments. Your dermatologist can create a treatment plan to meet your needs. Most plans include medication and skin care.
Always follow your dermatologist’s instructions. Using a treatment more often than prescribed or longer than prescribed can cause side effects.
Infant: Seborrheic dermatitis often completely disappears by 6 months to 1 year of age. It can return when the child reaches puberty.
Adolescent or adult: A few people see seborrheic dermatitis clear without treatment. More often, seborrheic dermatitis lasts for years. It tends to clear and flare without warning. Treatment often is necessary to control it.
