Call (786) 738-9515Persistent flaking, itching, redness, and irritation on your scalp, eyebrows, ears, or face usually isn't 'just dandruff.' It's most often seborrheic dermatitis — a chronic inflammatory skin condition that responds to treatment but tends to recur.
Here's what's actually causing your symptoms and how to control it long-term.
Dandruff: The mildest form — small white flakes, occasional itching, no visible redness. Affects up to 50% of adults.
Seborrheic dermatitis: More severe form — yellow, greasy scales over red, inflamed skin. Can spread beyond the scalp to eyebrows, sides of nose, ears, chest, and beard area.
Both are driven by the same factors: overgrowth of normal skin yeast (Malassezia) combined with individual immune sensitivity and excess oil production.
Common triggers: stress, cold/dry weather, hormonal shifts, certain medications, heavy oil-based hair products, and immune conditions. Patients with Parkinson's disease, HIV, or organ transplant recipients are more susceptible to severe forms.
It's not caused by poor hygiene — over-washing actually worsens it for many people.
Eyebrows and bridge of nose
Around the nostrils and smile lines
Behind and inside the ears
Beard and mustache areas
Mid-chest in men
Under heavy skin folds (less common)
Pyrithione zinc (Head & Shoulders): Antifungal, gentle, daily-use friendly.
Selenium sulfide (Selsun Blue): Antifungal, more potent.
Salicylic acid (Neutrogena T/Sal): Removes scale buildup.
Coal tar (Neutrogena T/Gel): Anti-inflammatory and antifungal.
Ketoconazole 1% (Nizoral): Strongest OTC antifungal — use 2–3x weekly, leave on 5 minutes before rinsing.
Rotate two different active ingredients (e.g., zinc and ketoconazole) for best results.
Ketoconazole 2% shampoo or foam: Stronger than OTC, used 2–3x weekly.
Ciclopirox shampoo: Alternative antifungal.
Topical corticosteroid solution/lotion: Quick relief for inflamed scalp; not for long-term use.
Topical calcineurin inhibitors (tacrolimus, pimecrolimus): Steroid-free option for face/eyebrow areas — safe long-term.
Oral antifungals: Reserved for severe, treatment-resistant cases.
Use a non-irritating cleanser, apply ketoconazole 2% cream to affected areas twice daily for 2 weeks, transition to maintenance 2–3x weekly. Topical calcineurin inhibitors are excellent for eyebrows and around the nose where steroids should be avoided.
For beards: use ketoconazole shampoo as a daily face wash on affected areas. Read the AAD treatment overview.
Once cleared, prevent recurrence with weekly to twice-weekly use of an antifungal shampoo. Most patients control symptoms indefinitely with this maintenance routine. Compare to other chronic conditions like eczema that also require ongoing care.

No — both dandruff and seborrheic dermatitis are non-contagious.
Yes — stress is a major flare trigger.
Some patients have permanent remission, especially with reduced stress or hormonal changes. Most need ongoing maintenance.
Generally not recommended — heavy oils can feed the yeast and worsen symptoms.
No — psoriasis has thicker, silvery scales and well-defined plaques. Both can affect the scalp and need to be distinguished by examination.
