Seborrheic Dermatitis (Cradle Cap, Facial Erythema & Greasy Scalp Scaling)
An authoritative clinical and educational profile of Seborrheic Dermatitis, covering Malassezia yeast-mediated cutaneous inflammation, greasy yellowish scaling and erythematous plaques across sebum-rich zones (scalp, nasolabial folds, glabella, pre-sternal chest), infant cradle cap, constitutional homeopathic supportive management, and emergency red flags for exfoliative erythroderma, secondary bacterial superinfections, and severe eczema herpeticum.

"Sudden explosive, severe, or treatment-refractory seborrheic dermatitis in a young adult is an established clinical indicator warranting HIV screening."
In simple words
Seborrheic Dermatitis is a chronic, relapsing inflammatory dermatosis characterized by well-demarcated erythematous plaques topped with greasy, yellowish, oily scales occurring predominantly in regions of high sebaceous gland density—including the scalp, face (nasolabial folds, glabella, eyebrows, beard area), retroauricular folds, external auditory canal, and upper central chest (pre-sternal region). Occurring in two distinct age populations—infants (infantile seborrheic dermatitis, presenting as thick greasy yellowish scalp crusts termed 'cradle cap' within the first 3 months of life) and adults (peak incidence between 30 and 60 years)—it is driven by an abnormal cell-mediated cutaneous inflammatory reaction to lipophilic Malassezia yeasts feeding on sebum lipids. In severe or sudden explosive forms, it may serve as an early cutaneous marker for underlying HIV infection or Parkinson's disease.
A chronic inflammatory skin disorder affecting areas rich in sebaceous glands, characterized by salmon-colored erythematous patches covered with greasy, yellowish, adherent scales and mild-to-moderate pruritus.
Common causes
- Malassezia yeast colonization: overgrowth of Malassezia globosa and Malassezia restricta whose lipases degrade sebum triglycerides into irritant unsaturated free fatty acids
- Cutaneous inflammatory and immune response: localized epidermal penetration of metabolites activates keratinocyte Toll-like receptors (TLR2), NF-kappaB signaling, and local production of pro-inflammatory cytokines (IL-1beta, IL-6, TNF-alpha, IL-8)
- Sebaceous lipid hyperproduction: androgenic stimulation of sebaceous gland activity provides a continuous lipid-rich metabolic microenvironment for yeast proliferation
- Epidermal barrier dysfunction: impaired stratum corneum ceramide synthesis and altered lipid composition increasing vulnerability to fungal by-products
- Neurological and neuroendocrine factors: altered sebum composition and autonomic dysregulation in neurodegenerative disorders (Parkinson's disease, post-stroke states, facial nerve palsy)
Risk Factors
- Infancy (0–3 months; maternal transplacental androgen stimulation) and Adulthood (30–60 years; male predominance)
- Immunosuppression: Human Immunodeficiency Virus (HIV/AIDS; prevalence exceeds 35–80% with sudden severe presentation), organ transplant recipients, and lymphoma
- Neurological and psychiatric disorders: Parkinson's disease, traumatic brain injury, stroke, depression, and chronic fatigue
- Emotional stress, severe fatigue, and cold, dry winter climate triggering acute flare-ups
- Alcohol abuse and chronic malnutrition
Common symptoms
- Well-demarcated salmon-pink or erythematous plaques covered with greasy, yellowish, oily, adherent scales
- Characteristic anatomical distribution: scalp ('cradle cap' in infants; diffuse greasy dandruff in adults), face (nasolabial folds, eyebrows, glabella, eyelashes [seborrheic blepharitis]), retroauricular creases, and sternal chest
- Mild to moderate pruritus (itching) and burning sensation, particularly on the scalp and face during sweating
- Cracking, weeping, and painful fissures in the retroauricular folds (behind the ears) and intertriginous body folds
- Waxing and waning clinical course with acute seasonal winter flares and spontaneous summer remissions
- Absence of nail changes (no oil drop spots or subungual hyperkeratosis) in uncomplicated seborrheic dermatitis
Clinical Red Flags
Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:
- Exfoliative Erythroderma (Leiner's Disease in infants): generalized, generalized severe redness and scaling covering >90% of the body surface area, accompanied by failure to thrive, persistent diarrhea, severe hypothermia, or dehydration (dermatological emergency requiring immediate pediatric/dermatology hospital admission)
- Secondary Bacterial Cellulitis / Impetiginization: rapidly spreading warm erythema, swelling, intense localized pain, honey-colored weeping crusts, facial cellulitis, or high spiking fever
- Severe Eczema Herpeticum (Kaposi's Varicelliform Eruption): sudden eruption of painful, punched-out, umbilicated vesicular lesions with high fever (viral emergency requiring immediate systemic acyclovir)
- Severe, explosive, treatment-refractory seborrheic dermatitis in a young adult (mandates urgent screening for underlying HIV infection)
Lifestyle & diet support
Wash face daily with a gentle, fragrance-free foaming cleanser, avoid alcohol-based skin toners, harsh soaps, and heavy petrolatum-based moisturizers that trap sebum, use lukewarm water rather than hot showers to prevent facial flushing, shave facial hair or maintain a trimmed beard if facial scaling persists beneath facial hair, spend safe brief periods in natural sunlight (UV radiation inhibits Malassezia growth), and avoid touching or picking at facial scales.
Treatment Approaches
Conventional Management
A multimodal topical strategy aimed at clearing scales, suppressing Malassezia burden, and soothing inflammation: (1) Scalp therapy: topical antifungal shampoos (Ketoconazole 2%, Ciclopirox 1%, Zinc Pyrithione 1–2%, Selenium Sulfide 2.5%) lathered and left for 5 minutes 2 to 3 times weekly; alternating with salicylic acid or coal tar shampoos for thick adherent crusts. (2) Facial and body therapy: topical antifungal creams (Ketoconazole 2% cream, Ciclopirox cream applied BID for 2–4 weeks). (3) Non-steroidal topical anti-inflammatory agents: Topical Calcineurin Inhibitors (Pimecrolimus 1% cream, Tacrolimus 0.1% ointment; highly effective steroid-sparing agents for facial and retroauricular areas avoiding steroid-induced skin atrophy or rosacea). (4) Mild low-potency topical corticosteroids (hydrocortisone 1% cream) for acute short-term flares (maximum 5–7 days). (5) Infantile cradle cap management: gentle massage with pure mineral or coconut oil to soften crusts followed by gentle brushing with a soft infant comb and washing with mild baby shampoo.
Homeopathic Approach
Homeopathic constitutional and skin remedies (such as Graphites, Sulphur, Natrum Muriaticum, Mezereum, Kali Sulphuricum, Calcarea Carbonica, Sepia Officinalis, Arsenicum Album, Petroleum, Thuja Occidentalis) serve as supportive care to ease facial redness, soothe itchy retroauricular fissures, and support skin barrier resilience alongside gentle cleansers, antifungal creams, and dermatologist follow-up.

Diagnosis & tests
Investigation Protocol
Diagnosed clinically based on characteristic morphology (greasy yellow scales on erythematous plaques) and anatomical distribution in sebum-rich areas. Dermoscopy displays yellowish greasy scales, dotted vessels, and atypical red loops. Microscopic 10% KOH preparation demonstrates yeast blastospores and pseudohyphae excluding dermatophyte infections. In patients presenting with unusually severe, explosive, sudden-onset, or treatment-refractory seborrheic dermatitis, diagnostic HIV antibody/antigen testing and neurological screening are clinically mandatory.
Differential Diagnosis
Differentiate Seborrheic Dermatitis from Plaque Psoriasis / Sebopsoriasis (thick, silvery-white micaceous scales on sharply defined erythematous plaques with Auspitz sign and nail pitting), Atopic Dermatitis (intense pruritus on flexural surfaces with elevated IgE), Rosacea (erythema and telangiectasias across central face without greasy yellow scales; triggered by spicy foods/heat), Contact Dermatitis, Lupus Erythematosus (malar butterfly rash sparing nasolabial folds, positive ANA), and Tinea Faciei.
