Dandruff: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Get emergency help for swelling of the lips, tongue, or throat, breathing difficulty, or collapse after applying a hair or scalp product.

    These may be signs of a severe allergic reaction rather than dandruff.

    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Be seen today

    Seek prompt medical care if your scalp becomes increasingly painful, hot, swollen, or starts draining pus, as these can be signs of infection.

    Fever with rapidly spreading redness also needs urgent assessment.

  3. 3

    Does any of this apply?

    Book an appointment

    Arrange a routine appointment if:

    • Symptoms continue after several weeks of correctly using an anti-dandruff shampoo
    • Itching, redness, or scaling is severe or regularly disrupts sleep
    • Scaling affects your face, ears, chest, or other areas
    • You have patchy hair loss, broken hairs, thick plaques, or scalp sores
    • Symptoms began after a new hair product and do not settle after stopping it
    • A child has marked scalp scaling or hair loss
    • The condition is affecting your confidence or daily life

Dandruff alone is not an emergency.

Every sign above is quoted from the sofidex article on Dandruff. If you are not sure, err upward — it is always reasonable to be checked.
