Understanding Dandruff​​

Dandruff refers to excessive shedding of dead skin cells from the scalp, often accompanied by itching, redness and irritation. While minor flaking is normal, abnormal scaling may indicate conditions like seborrheic dermatitis or fungal infections, with multifactorial causes.

​​Primary Causes​​

▌Fungal Dandruff (70%+ cases)

Malassezia furfur, a naturally occurring scalp fungus, triggers visible flakes when overgrowth disrupts keratinocyte renewal cycles.

▌Dry Scalp

Common in dry climates/seasonal changes, characterized by small, non-greasy flakes from compromised moisture barrier.

▌Seborrheic Dermatitis

Chronic inflammatory condition presenting with red, oily scalp and yellowish scales.

▌Contact Dermatitis

Irritants in haircare products or over-washing may damage scalp microbiome balance.

▌Other Contributors

•  Hormonal fluctuations

•  Stress & immune function

•  Genetic predisposition

•  Sebum overproduction
