Dandruff

Short summary: Dandruff is a common scalp condition that causes visible flaking and sometimes itching. It is often linked to seborrheic dermatitis, scalp oil balance, skin sensitivity, or overgrowth of yeast that normally lives on the skin.

Basic information about dandruff

Many people notice white or yellowish flakes on the scalp, hair, or shoulders together with itching. Symptoms may become worse with stress, cold weather, oily scalp conditions, or infrequent washing in some individuals. ^[1][2]

Dandruff is not simply a sign of poor hygiene. Diagnosis is often straightforward, but other conditions such as psoriasis, eczema, or fungal infection may need to be considered if symptoms are severe or unusual. Treatment often includes medicated shampoos and gentle scalp care. ^[1][2][3]

Short conclusion: Dandruff is common and usually manageable, but thick scales, hair loss, inflammation, or treatment-resistant symptoms should be medically assessed. ^[1][2]
