Scalp Ringworm in Children (Tinea Capitis): Patches and Treatment

Short answer: scaly bald patches on a child’s head, sometimes with tiny black dots where hairs have snapped, are very often scalp ringworm (tinea capitis), and it needs a doctor and a course of antifungal medicine taken by mouth, because creams and totkay can’t reach the fungus living inside the hair root.

A mother parts her son’s hair after school and finds a patch the size of a coin. The skin is grey and flaky, and the hairs there look chewed off close to the scalp. Is it the “coin-sized bald patch” people talk about, or dandruff, or something he picked up from a friend’s cap? This guide walks through scalp ringworm in children: how to spot it, why it won’t go away with a cream, what the doctor will do, and how to stop it moving round the family.

What scalp ringworm actually is (no worm involved)

Ringworm isn’t a worm. It’s a fungus from the same family that causes daad on the body and athlete’s foot, but on the scalp it behaves differently, because instead of just sitting on the skin it grows down into the hair follicle and into the hair shaft itself, so each hair turns weak and snaps off at the surface.

Think of a weed that has sent its roots below the paving stones. Spray the top all you like. The roots stay.

That’s why a cream fails.

It spreads by touch and by anything that touches heads, from combs, brushes, caps, dupattas and pillowcases to barber’s clippers and sometimes a kitten or puppy with patchy fur, which is why crowded classrooms and shared beds make it so common in South Asian families. Nobody’s fault.

How to recognise it: patches, black dots and the boggy lump

It varies. Look for any of these:

• Scaly patches: one or more round or oval areas with grey or white flakes, sometimes looking like stubborn dandruff in one spot.
• Broken hairs: short stubs a few millimetres long, or hairs snapped flush with the scalp that look like black dots.
• Itch: often, though not always.
• Swollen glands: small lumps at the back of the neck or behind the ears.
• A kerion: a soft, raised, boggy swelling that may ooze pus and feel tender. It looks like an abscess, but it’s the body over-reacting to the fungus.

A kerion frightens parents most. Please don’t let anyone squeeze it, cut it or put a hot poultice on it, because it needs a doctor soon and a kerion that’s left alone can leave a permanent bald scar where hair never returns.

Is it ringworm or alopecia areata?

Both give a coin-sized bald patch, which is why they get mixed up. Alopecia areata leaves smooth, clean skin with no flakes, no itch and no broken stubs; it’s an immune condition, not an infection, and it doesn’t spread. Ringworm is scaly, often itchy, and full of snapped hairs. Our alopecia areata guide covers the smooth kind. If you can’t tell, the doctor can, often just by looking and sometimes by taking a few hairs or scales for a lab test.

Age by age: who gets it and what to watch

• Under 6 months: rare. A scaly scalp at this age is usually cradle cap. Any oozing, spreading rash or fever in a young baby needs a doctor that day.
• 6 to 12 months: still uncommon. Don’t use any adult antifungal shampoo or cream without a doctor’s say.
• 1 to 3 years: starting to appear, often from older siblings or pets.
• 3 to 6 years: common. Nursery, madrassa and school spread it through caps and close play.
• Over 6: the most common group up to the early teens. It becomes rare after puberty, when the scalp’s natural oils change.

Why creams and totkay fail on the scalp

Parents often try an antifungal cream from the chemist first, because it worked for daad on the body, and on the scalp it may calm the surface for a week before the patch comes straight back, not because the cream is fake but because it simply can’t reach the fungus hiding inside each hair. Wrong tool.

Home fixes fail for the same reason, and some cause harm:

• Mustard oil, coconut oil, neem oil: they soften flakes, so the patch looks better, while the fungus carries on underneath.
• Mehndi, garlic paste, lemon, raw turmeric packs: these can burn a child’s scalp, and a burnt, raw patch is easier to infect.
• Kerosene or petrol: dangerous. They blister skin and the fumes are poisonous to breathe. Never.
• Steroid creams (the “mixed” tubes from the chemist): they hide the redness and let the fungus spread wider. We explain this trap in why steroid creams make daad worse.
• Shaving the head: it doesn’t remove the fungus in the follicle, and a razor can nick the skin and carry spores to new spots.

What the doctor will do

A GP, paediatrician or skin doctor will look at the patch, check the neck glands and may pull a few hairs or scrape some scale for a fungal test, and leaving the scalp unwashed and unoiled beforehand helps that test.

Treatment is almost always an antifungal medicine taken by mouth, as tablets or a liquid. The doctor chooses which one and works out the amount from your child’s weight. Courses usually run for several weeks, and stopping early is the most common reason ringworm returns. A medicated shampoo is often added for the child and sometimes the whole family, because it cuts down the spores that spread to others, even though it can’t clear the infection by itself.

Give it exactly as prescribed. Don’t swap, stop or share it; that’s the doctor’s decision, and so is adding anything else alongside it. Hair usually regrows once the fungus clears.

Stopping it spreading at home and school

1. Give every child their own comb and brush. Label them with a strip of tape.
2. Soak combs, brushes and hair clips in hot soapy water for 30 minutes, then rinse and dry, once a week during treatment.
3. Wash caps, topis, scarves, dupattas and pillowcases on the hottest wash the fabric allows, or soak in hot water, then dry in the sun.
4. Check every brother and sister’s scalp in good daylight. Part the hair in lines about 2 cm apart and look for flakes and broken stubs.
5. Ask your barber to clean clippers between customers, or take your own comb.
6. If a cat, kitten or dog has patchy fur, take it to a vet as well.

Most children can keep going to school once treatment has started, so tell the teacher kindly and ask that caps, helmets and combs aren’t swapped between friends in class or on the sports field.
