What should you know about little itchy bumps?

When the bumps are on the scalp, flaking and itch can occur with [Dandruff](/conditions/dandruff/) or [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/). Thickened, sharply defined areas with scale may occur with [Scalp Psoriasis](/conditions/scalp-psoriasis/). Tender bumps around hairs can suggest [Folliculitis](/conditions/folliculitis/). Intense itch with visible nits or close contacts who are also itchy raises the possibility of [Head Lice](/conditions/head-lice/).

The same symptom can have different causes, so note whether itch is worse at night, whether there is scale or discharge, and whether bumps follow hair follicles. Scratching can break the skin and make irritation or infection harder to judge.

Use lukewarm water, gentle products and clean hair tools; avoid picking and vigorous scratching. If flaking is present, a clinician or pharmacist may discuss [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/). If lice are suspected, use an appropriate [Head Lice Treatment](/treatments/medical-dermatology/head-lice-treatment/) and follow its instructions, including any advice about close contacts. Do not share combs, brushes or hats while checking the cause.

Arrange a review if itch persists, disturbs sleep, causes hair loss or does not improve with gentle care. Seek prompt attention for pus, spreading redness, fever, painful swelling, facial swelling or breathing difficulty. Broken skin from scratching may need assessment for secondary infection.

Ask whether the bumps are follicular, scaly or consistent with an infestation, and whether you need a scalp examination. Ask which products to stop, how long to use treatment and how to prevent reinfection if lice are found.
