Treatment for Seborrheic Dermatitis of the Scalp

Understanding the Condition

  • Seborrheic dermatitis presents with greasy yellowish scaling, itching, and secondary inflammation primarily affecting sebaceous areas including the scalp. The condition is more pronounced in patients with certain conditions such as Down syndrome, HIV infection, and Parkinson's disease. 1

Second-Line Treatment Options

  • The American Academy of Dermatology recommends moderate potency (class 2-5) corticosteroids for short periods (up to 4 weeks) to control inflammation in seborrheic dermatitis cases not responding to first-line therapy. Caution must be exercised with topical corticosteroids to avoid skin atrophy, striae, and other adverse effects. 2

  • Coal tar shampoos are recommended for seborrheic dermatitis involving the scalp according to clinical practice guidelines. 3

Special Considerations

  • Clinicians should check for possible nutrient deficiencies (thyroid function, vitamin D, zinc, ferritin) that may exacerbate seborrheic dermatitis. 5

  • Some patients may develop contact dermatitis to topical preparations, particularly neomycin which causes reactions in 5-15% of patients with chronic external otitis. 1
