Seborrheic dermatitis is a common skin condition in infants, adolescents, and adults. The characteristic symptomsscaling, erythema, and itchingoccur most often on the scalp, face, chest, back, axilla, and groin. Seborrheic dermatitis is a clinical diagnosis based on the location and appearance of the lesions. The skin changes are thought to result from an inflammatory response to a common skin organism, Malassezia yeast. Treatment with antifungal agents such as topical ketoconazole is the mainstay of therapy for seborrheic dermatitis of the face and body. Because of possible adverse effects, anti-inflammatory agents such as topical corticosteroids and calcineurin inhibitors should be used only for short durations. Several over-the-counter shampoos are available for treatment of seborrheic dermatitis of the scalp, and patients should be directed to initiate therapy with one of these agents.

What Causes Cradle Cap In Babies And Adults

What causes cradle cap is not entirely certain, but in babies it may be the result of overactive oil-producing sebaceous glands, which are stimulated by the motherââ¬â¢s hormones. These glands produce sebum, an oily or waxy substance that lubricates and waterproofs the skin.

Another factor contributing to cradle cap or seborrhea in adults may be the colonization of the sebaceous glands by natural yeasts, specifically particular subspecies of the genus Malassezia. It is possible that these yeasts do not cause cradle cap, but rather take advantage of the overproduction of sebum that is already happening.

It is also likely that stress, chemical irritants and dry, cold weather may play a role in causing cradle cap. Cradle cap is not caused by bacteria, allergies, lack of hygiene or lack of care. It is not contagious.

Cradle cap can be treated quite easily and will usually clear up within a few weeks or months.

In older people, cradle cap, or seborrheic dermatitis, can be caused by the same factors that lead to the condition in infants.

How To Get Relief From Itching And Flaking

To relieve itching at home, the following remedies may be helpful:

  • Moisturize: Apply a gentle moisturizer to your skin after showering or bathing to help prevent dry skin and flaking.
  • Opt for lukewarm water: Hot showers may feel amazing, but they can be rough on your skin. Try keeping baths and showers to five minutes and using lukewarm water that wont dry out irritated skin.
  • Go for unscented: When choosing household items that touch your skin like soaps or laundry detergents, look for gentle, unscented types since these are less likely to cause skin irritation.
  • Try coconut oil: Using coconut oil on the scalp has been shown to hydrate the skin and may reduce inflammation as well.
  • Look for tea tree oil: Tea tree oil has been used for other skin conditions like athletes foot, and a 2002 study found that shampoos infused with tea tree oil may be effective at treating dandruff.
  • Manage stress: Because stress can increase the risk of developing seborrheic dermatitis, find healthy ways to reduce stress like getting enough sleep, practicing mindfulness, and meeting with a therapist.

Getting The Right Diagnosis

As with any medical condition, seeking a proper diagnosis is critical to developing the right treatment plan. “The first and the most important part of caring for your skin condition is to get the right diagnosis,” says Dr. Shi. “Various skin rashes can often look similar and have very different treatment approaches. For example, some over-the-counter psoriasis treatments work by reducing skin thickness and scaling, and if used incorrectly on eczema skin, can actually cause an eczema flare.”

Dr. Shi says, “More often than not, people with these conditions may require a prescription strength medication. Therefore, it’s better to see a dermatologist to confirm the correct diagnosis and get an individualized treatment plan.” As each of the three conditions will fluctuate in severity over time, a treatment plan may require different approaches.
