Lice and Nits Removal

Lice crawl along the hair and scalp; nits are eggs cemented to hairs, commonly close to the scalp. Dandruff and product residue usually slide away more easily, while nits tend to stay attached. A nit can remain after a louse has been removed, so the practical question is whether live crawling lice can be found. An [Itchy Scalp](/symptoms/itchy-scalp/) or [Itching Worse At Night](/symptoms/itching-worse-at-night/) may prompt a check, but either symptom can arise from other scalp problems.

Wet the hair, add conditioner, and divide it into small sections. Place a fine-toothed comb at the roots, draw it through to the ends, and wipe it after each stroke so you can inspect what has been collected. Work around the whole scalp, paying attention behind the ears and at the nape. Repeat checks on the schedule advised for the treatment or by a healthcare professional. Wash or isolate items that touch the hair, and avoid sharing brushes, hats, pillows, and hair accessories. If live lice are detected, removal should be paired with an evidence-based product or [Head Lice Treatment](/treatments/medical-dermatology/head-lice-treatment/) advice.

Get medical advice if scratching has caused open skin, crusts, pus, marked redness, or swelling. Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) when live lice remain after careful treatment, the scalp problem keeps returning, or you cannot tell lice from another condition. Ask before using products on a very young child or on skin affected by eczema, allergy, or another scalp disorder.

Ask how to confirm live lice, which combing method suits the hair type, whether treatment is also needed, when to repeat the check, and how to assess household contacts.
