Seborrheic dermatitis is a common condition that affects the skin on your scalp. In babies, it is known as “cradle cap,” but it can also affect adults. It causes an itchy, scaly rash and dandruff. This condition can also affect oily areas of the body, such as the face and eyebrows, ears, eyelids, chest and back.
Seborrheic Dermatitis FAQs
The signs and symptoms of seborrheic dermatitis vary with age. The following paragraphs describe how it affects people of different ages.
Seborrheic dermatitis in infants
When an infant gets seborrheic dermatitis, it tends to form on the scalp, which is why it’s commonly known as cradle cap. Signs and symptoms of cradle cap include:
- Yellow, greasy scale on the scalp
- A thick layer of scale can cover the entire scalp
- The scale is often yellow to brownish in color
- With time, the scale becomes flaky and easily rubs off
In infants, seborrheic dermatitis also can form on the face, usually on a baby’s eyelids, around the nose, or ears. It can also form in the diaper area. In a few babies, seborrheic dermatitis covers most of the body. Most infants seem not to be bothered by seborrheic dermatitis, although cradle cap sometimes itches.
Seborrheic dermatitis in adults
In adults and adolescents, seborrheic dermatitis causes reddish, scaly patches on the skin that look greasy or moist. Scales can flake off and tend to be yellowish to white. The skin can itch, especially on the scalp and in the ear canal. Sufferers may also feel a burning sensation.
Patches tend to form in areas where the skin is oily, including:
- Scalp
- Ears (around and in the ear canal)
- Eyebrows (the skin beneath)
- Center of the face
- Eyelids
- Upper chest
- Upper back
- Armpits
- Genitals
People of all ethnicities and ages get seborrheic dermatitis. Infants 3 months of age and younger and adults between 30 and 60 years of age are most susceptible. People of all skin colors and ages get seborrheic dermatitis. You have a higher risk if you have any of the following medical conditions:
- HIV (About 85% of people infected with HIV develop seborrheic dermatitis)
- Acne, rosacea or psoriasis
- Parkinson’s disease
- Epilepsy
- Stroke or heart attack (recovering from)
- Alcoholism
- Depression
- An eating disorder
There is also a correlation between seborrheic dermatitis and taking the following medications: Interferon, lithium and Psoralen.
Researchers are still studying what causes this common skin disease, and they know the cause is complex. Many factors seem to work together to cause seborrheic dermatitis. These factors may include the yeast that normally lives on our skin, our genes, living in a cold and dry climate, stress and a person’s overall health.
Researchers have learned that it is not caused by poor personal hygiene, is not an allergy and doesn’t harm the body.
Treatments for Seborrheic Dermatitis
This is a condition that our Riverchase dermatologists frequently diagnose and treat.
If you think you may have seborrheic dermatitis, you should see a member of our dermatology team for a diagnosis. This common skin condition can look like psoriasis, eczema or an allergic reaction, but each of these skin conditions requires a different treatment.
To make a diagnosis, your doctor will review your medical history and perform a physical examination of the rash area. Sometimes seborrheic dermatitis is a sign of an underlying medical condition. If your dermatologist suspects this, medical tests may be necessary.
Although seborrheic dermatitis cannot be cured, there are benefits to getting treatment. Treatment can loosen and remove scale, prevent a skin infection, and reduce swelling and itch. The type of treatment a dermatologist prescribes varies with the patient’s age and where seborrheic dermatitis appears on the skin.
