Seborrheic Dermatitis
Manage seborrheic dermatitis clinically when distribution is typical, but perform targeted fungal testing or biopsy for atypical, refractory, or systemic presentations. Use site-directed antifungal therapy for control, brief anti-inflammatory treatment for flares, and maintenance therapy to reduce relapse.
Diagnosis
When clinical diagnosis is sufficient and when to test
Use morphology, site, age, and treatment response to determine whether apparent SD needs confirmation or diagnostic expansion.
Diagnose SD clinically when greasy scale with erythema is confined to typical seborrheic sites—scalp, central face, retroauricular skin, and upper chest—and the course is recurrent. Routine laboratory or instrumental testing is seldom required.

Obtain a KOH preparation from active scale when an annular advancing border, central clearing, alopecia, broken hairs, pustules, satellite lesions, or an atypical distribution raises concern for dermatophyte infection, tinea versicolor, or candidiasis. A positive KOH supports a fungal alternative or coexisting infection and should redirect treatment; KOH may also identify yeast forms in candidiasis.

Perform a skin biopsy when lesions remain diagnostically ambiguous after examination and targeted fungal evaluation, when psoriasis and SD coexist or cannot be distinguished clinically, or when presumed SD is severe, atypical, and unresponsive to local therapy. Scalp psoriasis more often shows neutrophilic parakeratosis, spongiform micropustules of Kogoj, and clubbed evenly elongated rete ridges; SD more often shows follicular plugging, shoulder parakeratosis, and prominent lymphocytic exocytosis.

In a child after infancy but before puberty, do not assume isolated scalp scale is SD; prioritize tinea capitis, atopic dermatitis, and psoriasis in the differential. pedsinreview aappublicationspedsinreview aappublicationsDifferential Diagnosis of Seborrheic Dermatitis | Pediatrics In Review | American Academy of Pediatrics
Use dermoscopy as an adjunct when demodicosis or rosacea is plausible: SD shows patchy dotted vessels with fine yellow scale, whereas erythematotelangiectatic and papulopustular rosacea show linear vessels in a polygonal network.

Consider HIV or other immunodeficiency, neurologic disease, cardiac disease, and alcoholic pancreatitis as predisposing contexts when SD is unusually extensive or difficult to control. PubMedPubMedSeborrhoeic dermatitis - PMC
Initial Treatment
Site-directed treatment for adults
Select a topical antifungal foundation, then add anti-inflammatory therapy only when erythema or pruritus requires faster flare control.
For mild-to-moderate adult scalp SD, begin ketoconazole 1% to 2% shampoo twice weekly for 4 weeks. Other supported topical classes include ciclopirox or miconazole formulations, mild- to moderate-potency topical corticosteroids, and keratolytic or humectant agents such as propylene glycol.

For limited facial or body disease, use topical ketoconazole, ciclopirox, or clotrimazole. Mild- to moderate-potency topical corticosteroids can be used for inflammatory disease; choose the shortest effective exposure because SD is recurrent and treatment frequently becomes intermittent.

Topical calcineurin inhibitors are an off-label option for facial SD when steroid exposure is undesirable or repeated anti-inflammatory treatment is needed. Pimecrolimus 1% cream is not approved for SD, although it is used in practice for this indication.

Maintenance after control
Plan maintenance at the first successful response because adult SD relapses. Ketoconazole 2% shampoo once weekly for 6 months reduced relapse in the cited adult scalp data; a separate treatment table recommends once-weekly ketoconazole or ciclopirox maintenance after induction.

Escalation
Approach to severe, resistant, or extensive disease
Failure of topical treatment should trigger diagnostic reassessment before systemic treatment.
Classify disease as refractory only after confirming that the eruption is SD rather than scalp psoriasis, dermatophyte infection, candidiasis, contact dermatitis, rosacea, or demodicosis. Re-examine the distribution, perform KOH testing when fungal disease is plausible, and biopsy persistent diagnostically uncertain plaques.

For severe or resistant adult SD, oral therapies have been reported, including itraconazole, terbinafine, fluconazole, ketoconazole, prednisone, and isotretinoin; however, the summarized evidence includes open trials and case reports for several agents, and professional society guidelines and SD-specific labeled treatment options remain limited. Systemic treatment should therefore be reserved for selected refractory cases after diagnostic confirmation and specialist-level risk assessment.

Do not use an unusually severe presentation solely as a reason to intensify topical therapy. Evaluate for relevant predispositions, including HIV infection, neurologic disease such as Parkinson disease, neurologic injury, ischemic heart disease, and alcoholic pancreatitis, when clinical context supports that workup.

Pediatrics
Cradle cap and pediatric seborrheic dermatitis
Age and systemic findings determine whether conservative management is appropriate or whether presumed SD needs investigation.
For uncomplicated infantile scalp SD, counsel that the condition is generally favorable and may completely resolve by 5 to 6 months without treatment. This expectation supports a conservative approach when the infant is otherwise well and lesions are limited to typical greasy scalp scale. Wolters Kluwer+1Wolters KluwerPediatric Dermatitis Seborrhoica - A Clinical and... : Indian Dermatology Online JournalPubMedInterventions for infantile seborrhoeic dermatitis (including cradle cap) - PMC
For infant scalp disease requiring treatment, options listed for mild disease include selenium sulfide 2.5% shampoo, zinc pyrithione 1% to 2% shampoo, ciclopirox 1% shampoo or 0.77% gel, and ketoconazole 1%. Hydrocortisone 1% liniment or 0.1% lotion is listed for moderate-to-severe scalp disease; for non-scalp involvement, ciclopirox 1% cream or ketoconazole 1% cream is listed for mild disease and hydrocortisone 1% liniment or cream for moderate-to-severe disease. PubMedPubMedPediatric Dermatitis Seborrhoica - A Clinical and Therapeutic Review
Treatment evidence in infantile SD remains uncertain, and there is no consensus treatment recommendation. Avoid automatically treating all cradle cap aggressively when the disease is asymptomatic and self-limited; use medication when extent or inflammation justifies intervention and reassess if it does not improve. PubMed+1PubMedInterventions for infantile seborrhoeic dermatitis (including cradle cap) - PMCPubMedPediatric Dermatitis Seborrhoica - A Clinical and Therapeutic Review
In adolescents, mild scalp options listed include salicylic acid 3% shampoo, tar 1% to 2% shampoo, selenium sulfide 2.5% shampoo, zinc pyrithione 1% to 2% shampoo, and ketoconazole 1% to 2% shampoo. PubMedPubMedPediatric Dermatitis Seborrhoica - A Clinical and Therapeutic Review
For pediatric lesions that are unresponsive to appropriate local therapy or accompanied by petechiae, hemorrhagic lesions, lymphadenopathy, or systemic symptoms, evaluate for Langerhans cell histiocytosis rather than persisting with empiric SD treatment. pedsinreview aappublications+1pedsinreview aappublicationsDifferential Diagnosis of Seborrheic Dermatitis | Pediatrics In Review | American Academy of Pediatricspublications aapSeborrheic Dermatitis | Pediatric Care Online | American Academy of Pediatrics
