Head lice

What it is

Head lice are tiny insects that live in hair and feed on the scalp. They spread through head-to-head contact. They are common in school children and are not a sign of dirty hair.

How it works

Lice are tiny insects that live on the scalp and lay eggs (nits) glued to hair shafts.

Why it matters on darker skin

Lice affect all hair types. Tightly coiled hair is less often affected, but braids and dense hair make lice and eggs harder to see and remove.

Causes and triggers

Head-to-head contact; not a sign of dirt.

What helps — and why it works

Wet-comb conditioned hair section by section with a fine-tooth lice comb every 3 to 4 days for at least two weeks. Pharmacy lice treatments can be used as directed. Check everyone in the household and treat only those with live lice. Wet combing with conditioner every 3–4 days: removes lice before they breed. Expected timeline: 2 weeks. Approved lotions: kill lice. Expected timeline: repeat after 7 days.

What to avoid and why

Avoid kerosene, petrol or insecticides on the scalp; these are dangerous. Shaving the head is not necessary.

Common mistakes

• Kerosene or insecticides.
• Treating without seeing live lice.

Caring for children's skin

Children's skin is thinner, loses water faster and absorbs more of what is applied to it relative to body size, so simpler is safer. For most children a short lukewarm bath, a fragrance-free soap substitute and a plain emollient are all that is needed, plus shade, clothing and sunscreen from six months of age. Avoid adult products, essential oils, antiseptics in bath water, bleaching or 'toning' creams, and cosmetic treatments such as relaxers and gel nails. Medicines and medicated creams should be used only as a doctor, nurse or pharmacist advises, and in children Melanin & Me does not offer photo checks: a clinician should see the child. Trust your instincts as a parent: a child who is unusually sleepy, floppy, not feeding, breathing fast or has a rash that does not fade when pressed with a glass needs urgent care. Keep a simple record — photos and dates — of rashes that come and go, as this helps the doctor.

Products, medicines and when to worry

When choosing products for children, look for fragrance-free formulas with short ingredient lists, and avoid adult acne, anti-ageing or lightening products, essential oils and talc. Medicated creams — including steroid creams, antifungals and antibiotics — are safe and helpful when prescribed for the right condition and used for the right length of time, but mixed creams sold over the counter can contain strong steroids that are unsafe for children. Sunscreen is suitable from six months of age; younger babies should be kept in the shade and covered. Do not give medicines intended for adults, and ask a pharmacist about the right medicine for a child's age and weight. Seek urgent care for any rash with fever and a very unwell child, a rash that does not fade under a glass, swelling of the face or lips, or blistering of the mouth or eyes.

Questions to ask your doctor or pharmacist

Useful questions include: What do you think is causing this? Is it likely to come back, and how can I prevent it? Which products should I stop? How long before I should expect improvement, and when should I come back if it isn't better? Are there side effects to watch for? Is this treatment safe if I am pregnant, breastfeeding or for my child? Writing your questions down, bringing your products (or photos of their labels) and taking dated photos of the problem make an appointment much more useful.
