What should you know about dry dandruff?

Dandruff is a scaly scalp condition. Flakes may be fine and white, while an irritated scalp can also feel tight or itchy. Seborrheic dermatitis can cause more noticeable scale, redness, or greasy flakes and may affect areas around the ears, eyebrows, or nose as well as the scalp. A flaky scalp can also be aggravated by harsh cleansing, very hot water, scratching, or a product that does not suit you.

The appearance alone cannot confirm the cause. Notice whether the scale is dry or oily, whether the scalp is red, and whether hair products or a change in washing routine preceded the problem. These details help a clinician distinguish ordinary dandruff from eczema, psoriasis, or contact irritation.

Wash gently and rinse thoroughly, using lukewarm water rather than very hot water. Avoid picking flakes, because broken skin can become sore and more inflamed. If a clinician or pharmacist recommends a medicated shampoo, follow its directions about how long it should remain on the scalp and how often to use it. A treatment aimed at dandruff may need regular use to control recurring scale.

Keep styling products away from irritated skin while you identify triggers. If symptoms continue, a dermatologist can consider medicated shampoo treatment or topical antifungal treatment when those options fit the findings.

Arrange a medical review if the scalp is painful, swollen, bleeding, crusted, or developing areas of hair loss. Seek advice when itching disrupts sleep, the rash spreads beyond the scalp, or careful use of an appropriate shampoo does not improve the flaking. Prompt assessment is also sensible when a new product is followed by burning or marked redness.

Could this be dandruff, seborrheic dermatitis, eczema, psoriasis, or a product reaction? Which shampoo suits my scalp, and how should I use it? What signs would mean I should stop a product or return for another examination?
