What Are These Bumps on My Son’s Scalp? Common Causes and Solutions
Noticing unusual bumps or rashes on your child’s scalp can be unsettling. As a parent, your first instinct might be to worry—Is this an infection? Allergic reaction? Something serious? While scalp bumps in children are rarely a cause for panic, understanding their potential causes can help you address the issue confidently. Let’s explore common reasons for scalp bumps in kids and practical steps to manage them.

1. Folliculitis: Tiny Red Bumps from Irritation
Folliculitis occurs when hair follicles become inflamed, often due to bacteria, fungi, or irritation from sweat, oils, or tight hairstyles (like braids or ponytails). These bumps may look like small red pimples, sometimes with a white tip. They can itch or feel tender.
What to do:
– Gently wash the scalp daily with a mild, fragrance-free shampoo.
– Avoid harsh hair products or tight hairstyles that trap sweat.
– For persistent cases, consult a pediatrician. They may recommend an antibacterial or antifungal shampoo.

2. Head Lice: The Itchy Culprit
Head lice are a common childhood nuisance. These tiny parasites lay eggs (nits) near the scalp, causing intense itching. The bumps themselves are often red and may appear scratched due to constant rubbing.
What to do:
– Check for lice and nits (small white or gray specks attached to hair shafts).
– Use an over-the-counter lice treatment shampoo, and carefully comb out nits with a fine-toothed comb.
– Wash bedding, hats, and brushes in hot water to prevent reinfestation.

3. Cradle Cap (Seborrheic Dermatitis)
Common in infants, cradle cap causes greasy, yellowish scales or crusty patches on the scalp. Though harmless, it can sometimes lead to red bumps or mild inflammation beneath the scales.
What to do:
– Gently massage the scalp with baby oil or coconut oil to loosen scales.
– Use a soft brush to remove flakes after bathing.
– For older children, a medicated shampoo with ingredients like selenium sulfide or ketoconazole may help.

4. Allergic Reactions or Contact Dermatitis
New shampoos, conditioners, or hair products can trigger allergic reactions, resulting in itchy red bumps, dryness, or swelling. Even “gentle” products labeled for kids may contain fragrances or dyes that irritate sensitive skin.
What to do:
– Stop using any new products immediately.
– Rinse the scalp thoroughly with lukewarm water.
– Apply a hypoallergenic moisturizer or hydrocortisone cream (with a doctor’s guidance) to soothe itching.

5. Ringworm (Tinea Capitis)
Despite its name, ringworm is a fungal infection—not a worm. It causes round, scaly patches with broken hairs, sometimes accompanied by red bumps. This condition is contagious and requires treatment.
What to do:
– See a pediatrician for diagnosis. Oral antifungal medication is typically prescribed.
– Avoid sharing combs, hats, or towels to prevent spreading the infection.
—
6. Heat Rash or Sweat Bumps
Hot weather or overdressing can lead to blocked sweat glands, creating small, prickly bumps on the scalp or neck. These are usually harmless but may cause discomfort.
What to do:
– Keep your child cool and dry. Opt for breathable fabrics like cotton.
– Rinse the scalp with cool water and pat dry gently.
—
7. Chickenpox or Viral Rashes
Though less common today due to vaccines, chickenpox can still occur. It causes fluid-filled blisters that crust over, often starting on the scalp, face, or torso. Other viral rashes (like hand, foot, and mouth disease) might also involve scalp bumps.
What to do:
– Monitor for fever, fatigue, or spreading rashes.
– Keep your child hydrated and avoid scratching to prevent scarring.
– Consult a doctor for diagnosis and symptom management.

When to See a Doctor
Most scalp bumps resolve with simple home care, but seek medical advice if:
– Bumps worsen or spread rapidly.
– Your child has a fever, swollen lymph nodes, or signs of infection (pus, warmth, pain).
– The scalp becomes excessively scaly, inflamed, or loses hair.

Prevention Tips
– Keep the scalp clean: Regular washing with gentle products prevents buildup of oils and sweat.
– Avoid irritants: Opt for hypoallergenic shampoos and skip heavy styling products.
– Check for lice routinely: Especially after sleepovers or camp.
– Teach hygiene habits: Discourage sharing combs, hats, or helmets.
