What causes excessive dandruff?

Dandruff is usually caused by excessive proliferation and shedding of skin cells on the scalp. This may be due to several reasons: 1. Malassezia infection: Overgrowth of the fungus Malassezia on the scalp can trigger seborrheic dermatitis, leading to increased oil production and excessive dandruff. 2. Excessive sebum production: Too much sebum provides an ideal environment for Malassezia growth, stimulating dandruff formation. 3. Dry skin: A dry climate or the use of strong degreasing shampoos can cause excessive dryness of the scalp, resulting in flaky dandruff. 4. Stress and hormonal changes: Psychological stress, hormonal fluctuations, or certain medications may also affect scalp health and trigger dandruff. 5. Poor lifestyle habits: Irregular diet, lack of sleep, and excessive consumption of oily foods may also worsen dandruff problems. For daily care, maintain scalp cleanliness and avoid over-washing to prevent irritation. Follow a healthy diet, consuming more foods rich in zinc. Ensure adequate sleep and reduce stress.
