Treatment Options for Seborrheic Dermatitis

The most effective treatment for seborrheic dermatitis combines topical antifungal medications to reduce Malassezia yeast with topical anti-inflammatory agents to control inflammation and itching. 1

First-Line Treatments

Topical Antifungals

• Ketoconazole 2% cream is FDA-approved for seborrheic dermatitis and should be applied to affected areas twice daily for four weeks or until clinical clearing 2
• Ketoconazole works by impairing the synthesis of ergosterol, a vital component of fungal cell membranes, reducing Malassezia ovale populations 2
• Other effective topical antifungals include ciclopirox and clotrimazole 3

Anti-inflammatory Agents

• Topical hydrocortisone is effective for temporarily relieving itching and inflammation associated with seborrheic dermatitis 4
• Mild to moderate potency corticosteroids can be used for short-term management of inflammation 3
• Avoid long-term use of topical corticosteroids, especially on the face, due to risk of skin atrophy, telangiectasia, and tachyphylaxis 1

Treatment by Affected Area

Scalp Seborrheic Dermatitis

• Antifungal shampoos containing ketoconazole, selenium sulfide, or piroctone olamine are effective first-line treatments 5
• For thick, scaly areas, keratolytic shampoos containing salicylic acid or coal tar can help reduce scaling 6
• For moderate to severe cases, topical corticosteroid solutions, foams, or oils can be used short-term 6

Facial and Body Seborrheic Dermatitis

• Ketoconazole 2% cream applied twice daily for four weeks is the standard treatment 2
• Avoid alcohol-containing preparations on the face as they may increase skin dryness 1
• Topical calcineurin inhibitors (tacrolimus, pimecrolimus) can be considered as steroid-sparing agents for facial involvement 3

Treatment for Different Severities

Mild Cases

• Gentle skin care with mild, non-soap cleansers and moisturizers to reduce dryness and scaling 1
• Over-the-counter antifungal shampoos for scalp involvement 6
• Ketoconazole 2% cream for facial and body involvement 2

Moderate to Severe Cases

• Combination therapy with antifungal agents and short-term topical corticosteroids 5
• For resistant cases, consider systemic antifungal drugs like terbinafine or itraconazole 3
• Narrowband UVB phototherapy has shown efficacy in treatment-resistant cases 1

Special Populations

Infants (Cradle Cap)

• Often self-resolves by 6 months of age 6
• Mild cases can be treated with mineral oil to loosen scale followed by gentle combing 6
• For more severe cases, consider baby shampoos with emollient agents or medical device shampoos containing piroctone olamine 3

Common Pitfalls and Caveats

• If no clinical improvement is seen after the treatment period, the diagnosis should be reconsidered 2
• Distinguish seborrheic dermatitis from similar conditions like psoriasis, atopic dermatitis, and contact dermatitis, which require different treatment approaches 1
• Secondary bacterial infection may occur and should be treated with appropriate antibiotics if present 1
• In people with darker skin, erythema may be less apparent, and postinflammatory pigmentary changes might be a presenting sign 6

Treatment Algorithm

1. Start with topical antifungal (ketoconazole 2% cream) twice daily for facial/body involvement or antifungal shampoo for scalp involvement 2, 5
2. For significant inflammation, add short-term topical corticosteroid 1
3. For maintenance, continue antifungal treatment with reduced frequency 7
4. For resistant cases, consider systemic antifungals or phototherapy 3
