What should you know about constant dandruff?

Dandruff is visible shedding from the scalp. Flakes may be white and dry, or yellowish and greasy, and itching can occur alongside them. Seborrheic dermatitis can cause recurring flaking with redness or irritation, especially around the scalp, hairline, ears, or eyebrows. Product buildup, infrequent cleansing, and sensitivity to hair products can also keep the scalp unsettled. Persistent flakes do not by themselves identify one cause.

Use a medicated shampoo according to its label or a clinician’s instructions, and allow it to contact the scalp for the recommended time before rinsing. Apply it to the scalp rather than only the hair lengths. Avoid scratching, very hot water, and heavy styling products that leave residue. A gentle routine between medicated washes may reduce irritation. If symptoms continue, a dermatologist can check whether dandruff, seborrheic dermatitis, or another scalp problem is present and may recommend medicated shampoo treatment or topical antifungal treatment.

Arrange a dermatology assessment when flaking persists despite appropriate shampoo use, returns quickly, or comes with marked redness, thick plaques, pain, oozing, crusting, or areas of hair loss. Seek prompt care for swelling around the eyes or face, fever, or rapidly worsening tenderness. These features may point beyond uncomplicated dandruff and need an examination.

Ask which scalp condition best fits the pattern, how often to use a medicated product, whether another treatment is needed, and which ingredients or styling habits could be aggravating the scalp. Mention any new products, skin conditions, or hair loss.
