Treating and Managing Seborrheic Dermatitis


Seborrheic dermatitis will affect roughly half of all infants, making knowing how to treat and manage it key.

Cradle cap—or seborrheic dermatitis (SD)—is a common dermatologic condition that affects nearly half of all infants at some point in the first few months of their lives.1

This article will explore how to recognize and diagnose SD, as well as tips for treating and managing this condition.

What is SD?

SD is a chronic inflammatory skin condition sometimes referred to as cradle cap when it appears on the heads of infants, said Sherry G Cohen, NP-C, a family nurse dermatology practitioner in Lutherville, Maryland. It’s a common disease that is usually diagnosed clinically, and can present with mild disease lasting 4 to 6 weeks on average, but can last as long as a year.2

SD and dandruff fall into the same group of diseases that cause dry, flaky skin in the seborrheic areas of the body. Although dandruff is limited to the scalp alone, SD can affect other areas like the face, ears, nose, and eyelids.

This condition is most common during 3 stages of life1:

  • The first 3 months of infancy
  • During puberty
  • Between the ages of 40 and 60 years

The scalp is most commonly affected in infants, earning this condition the name of cradle cap, but the face and diaper areas can also show signs of SD. It’s also important to know how it may appear differently on other parts of the body.1

  • Scalp: Red to yellow plaques coated by thick, greasy scales
  • Face and neck: Red or pink flaky plaques that can appear on the forehead, eyebrows, eyelids, nasolabial folds, and retro-auricular areas
  • Body folds: Moist, shiny but non-scaly lesions common in the neck, armpits, and groin areas
  • Trunk: Redness and scaling as limited plaques throughout the lower abdomen

Generalized SD is rare and is often a sign of other conditions such as Leiner’s disease or immunodeficiencies. In these cases, itching is mild or absent with widespread redness, and other symptoms like diarrhea or failure to thrive may be evident.1

Only about 2% to 5% of teenagers experience SD, and by this age it tends to appear as an itchy, scaly rash on the scalp, face, chest, and skin folds. Although SD affects different genders and ethnicities equally, darker-skinner children may have areas of more pronounced hypopigmentation that lasts for weeks after an area of SD has cleared.3

The exact cause of SD is unknown, Cohen said, but androgens passed from mother to baby during pregnancy are believed to play a role.

“In newborns and infants, androgens stimulate the growth of the child's sebaceous glands that might drive the process,” Cohen stated, adding that a yeast called Malassezia has been found to grow in higher concentrations on people with SD, possibly as a result of an inflammatory reaction to the yeast.

Diagnosing SD

Making a clinical diagnosis of SD takes a few steps, particularly in ruling out other possible causes for dermatitis.

Differential diagnoses for SD can include things like:

  • Psoriasis
  • Contact dermatitis
  • Langerhan cell histiocytosis
  • Acrodermatitis enteropathica
  • Nutritional deficiency
  • Atopic dermatitis
  • Tinea capitis
  • Rosacea
  • Systemic lupus erythematous

In young children, a diagnosis can be narrowed based on how the dermatitis developed, Cohen added.

“Psoriasis usually starts in the diaper area and is well delineated. In infants, seborrheic dermatitis and atopic dermatitis can look very similar. The best way to distinguish them is by location, and the presence of intense itching in atopy,” Cohen explained. “Both can be red and scaly on the scalp. The rash of seborrheic dermatitis usually involves the skin folds and diaper area which are usually spared in atopic dermatitis. In infants atopic dermatitis often appears on the face, shins and forearms and other exposed areas that they can scratch. Contact dermatitis is often seen on the face or diaper area and is also itchy.”

A history and physical are the primary tools of diagnosis for SD, although skin biopsies may be performed in rare or complicated cases.

Management and treatment of SD

Infantile SD often resolves without treatment in a few months, Cohen said, but treatment options for persistent or symptomatic lesions can include medications like:

  • Low potency topical steroids such as hydrocortisone 1 % ointment
  • Topical calcineurin inhibitors like pimecrolimus cream or tacrolimus ointment depending on age
  • Topical antifungal creams, ointments, or shampoos like ketoconazole or selenium sulfide

Other remedies that may help to soothe the affected areas include oil preparations like mineral oil. This can soften and loosen the scales caused by SD, making it easier to separate the hair from the scalp, Cohen stated.

For areas that are not as sensitive as the face or intertriginous areas, a higher potency topical steroid can be used sparingly for short courses, whereas antifungals are preferred for long-term therapy, she added, explaining that studies have shown similar efficacy between these 2 treatments with lower adverse effects in the antifungals.4,5,6,7

Other medicated shampoos and treatments that might be used include zinc pyrithione, coal tar, and ciclopirox olamine. Rarely, in the most severe cases, antifungals are given orally for systemic effect, Cohen said.

A referral to a pediatric dermatologist may be appropriate in cases of SD that are complicated, prolonged, or appear with other symptoms.
