Dandruff

Dandruff is a common scalp condition causing flaking of dead skin, often accompanied by an itchy or oily scalp. The flakes can be dry and fine or larger and greasy, and may be more noticeable on dark clothing or after scratching. The most common causes include: Seborrheic dermatitis; dry scalp; sensitivity to hair care products; a yeast called Malassezia.

Dandruff becomes an emergency when it is unusually severe, sudden in onset, accompanied by other serious symptoms (chest pain, difficulty breathing, fainting), or occurs in vulnerable individuals such as infants, the elderly, or people with serious chronic conditions.

Diagnosis of Dandruff begins with a detailed medical history and physical examination of the scalp. Your doctor may order blood tests, urine analysis, imaging studies (X-ray, ultrasound, MRI), or refer you to a specialist depending on suspected causes. Early diagnosis leads to faster, more effective treatment.

Mild cases of Dandruff can often be managed with self-care: Wash hair regularly with a mild or medicated anti-dandruff shampoo; avoid scratching the scalp; and limit the use of heavy styling products. If flaking and itching persist despite consistent shampoo use over several weeks. However, if symptoms are severe, persistent, or worsening, always seek medical attention rather than relying solely on home remedies.

Dandruff is typically classified as chronic. Acute forms usually resolve within a few days to weeks with appropriate care. Chronic or recurrent dandruff may persist for months and requires longer-term management by a healthcare professional.

You should see a doctor if: See a doctor if dandruff is severe; causes significant redness or soreness; does not improve with regular use of anti-dandruff shampoo. Early evaluation by a healthcare professional ensures an accurate diagnosis and prevents complications.
