Three years of persistent dandruff strongly suggests seborrheic dermatitis â a chronic scalp condition driven by an overgrowth of a naturally occurring yeast (Malassezia). Moving to Greater Noida with its pollution, hard water, humidity changes, and stress can definitely trigger or worsen this condition. Shaving the hair does not treat the underlying problem; the dandruff will return if the scalp is not treated. Start using a medicated antifungal shampoo containing Ketoconazole 2% (e.g., Nizral) â use it twice a week, lather and leave it on the scalp for 5 minutes before rinsing. Continue for at least 4â6 weeks. Avoid hot water on the scalp, reduce oily hair products, and manage stress. If there is itching, redness, or thick flakes not improving after 4â6 weeks, a dermatologist can prescribe a topical steroid or a stronger antifungal treatment.
Next Steps
See a Dermatologist for proper evaluation and prescription treatment if ketoconazole shampoo alone does not control it in 4â6 weeks. Please consult me directly on Practo for a detailed evaluation.
