What should you know about Vichy anti dandruff?

Dandruff causes loose flakes and may come with itch or an oily, irritated scalp. It can overlap with [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/), which may also affect the eyebrows, ears, or sides of the nose. A product labelled anti-dandruff may contain cleansing or antifungal ingredients, but formulas differ, so check the label rather than assuming every bottle works in the same way. [Dandruff](/conditions/dandruff/) is common and is not caused by poor personal hygiene.

Follow the bottle directions, work the shampoo into the scalp rather than only the hair, and allow the recommended contact time before rinsing. Use lukewarm water and avoid vigorous scratching, which can break the skin. Keep the product away from the eyes and rinse well. If the scalp becomes sore or irritated, stop and reassess the routine. A clinician may recommend [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) or [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) when ordinary care is not enough.

Arrange medical advice for thick plaques, bleeding, pus, marked redness, hair loss, or a painful scalp. Seek help if severe itch prevents sleep, symptoms spread beyond the scalp, or flaking continues despite careful use. [Itchy Scalp](/symptoms/itchy-scalp/) and [Flaky Scalp](/symptoms/scalp-flaking/) can have causes other than dandruff, including psoriasis, eczema, contact allergy, or infection, so treatment depends on the diagnosis.

Ask which ingredient suits your scalp, how often to use it, how long to continue, and whether you should alternate it with a gentle shampoo. Mention hair dye, oils, styling products, new medicines, and any rash on other body areas. A clinician can also check whether irritation is from the product itself or whether another scalp condition is present.
