Common Causes of Scalp Bumps in Children
1. Cradle Cap (Seborrheic Dermatitis)
Common in infants and toddlers, cradle cap appears as greasy, yellowish, scaly patches or raised bumps on the scalp. It’s caused by overactive oil glands and isn’t contagious or painful. Though it might look concerning, gentle washing with a mild baby shampoo and brushing with a soft brush can help loosen flakes. In stubborn cases, pediatricians may recommend medicated shampoos.
2. Folliculitis
This occurs when hair follicles become inflamed, often due to bacteria, fungi, or irritation from sweat, tight hats, or hair products. Folliculitis bumps resemble small red pimples, sometimes with pus. Keeping the scalp clean, avoiding harsh products, and using warm compresses can help. Persistent cases may require antibiotic ointments.
3. Head Lice
Lice infestations are a frequent culprit in school-aged children. These tiny insects cause itchy, red bumps that result from scratching. Look for nits (lice eggs) attached to hair shafts or live lice moving near the scalp. Over-the-counter lice treatments, thorough combing, and washing bedding/clothing are essential to eliminate them.
4. Contact Dermatitis
Allergic reactions to shampoos, conditioners, or hair dyes can trigger red, itchy bumps. The rash often appears shortly after exposure. Switching to hypoallergenic products and rinsing the scalp thoroughly usually resolves the issue. A pediatrician may suggest antihistamines or corticosteroid creams for severe itching.
5. Heat Rash (Miliaria)
Hot weather or overdressing can block sweat glands, leading to tiny red bumps on the scalp, neck, or forehead. Keeping your child cool, dressing them in breathable fabrics, and avoiding heavy creams can prevent and relieve heat rash.
6. Chickenpox or Viral Infections
Viral illnesses like chickenpox may cause itchy, fluid-filled blisters anywhere on the body, including the scalp. These bumps often come with fever or fatigue. While most viral rashes resolve on their own, consult a doctor for proper diagnosis and symptom management.
7. Scalp Psoriasis or Eczema
Chronic conditions like psoriasis (thick, scaly patches) or eczema (dry, inflamed skin) can affect the scalp. These require medical guidance for long-term management, often involving prescription creams or shampoos.
8. Insect Bites or Stings
Mosquitoes, fleas, or other insects can leave behind itchy, swollen bumps. Clean the area with soap and water, apply a cold compress, and monitor for signs of an allergic reaction (e.g., difficulty breathing).
9. Cysts or Lipomas
Rarely, harmless growths like epidermoid cysts (filled with keratin) or lipomas (fatty lumps) may develop. These are typically painless but should be evaluated by a doctor to rule out abnormalities.

When to See a Doctor
Most scalp bumps aren’t emergencies, but seek medical advice if your child experiences:
– Persistent itching or pain that disrupts sleep or daily activities.
– Signs of infection: Increasing redness, warmth, pus, or swollen lymph nodes.
– Fever or lethargy accompanying the rash.
– Rapid spread of bumps to other body parts.
– No improvement after a week of home care.
A pediatrician can perform exams, take skin swabs, or order blood tests to identify the cause and recommend targeted treatments.

Home Care Tips for Mild Cases
For non-serious bumps, try these strategies:
– Gentle Cleansing: Use fragrance-free, hypoallergenic shampoo to avoid irritation.
– Avoid Scratching: Trim your child’s nails and distract them from scratching to prevent infection.
– Cool Compresses: Soothe itching and reduce swelling with a damp, cool cloth.
– Moisturize: Apply a mild, non-greasy moisturizer if the scalp is dry or flaky.
– Identify Triggers: Track products, foods, or environments that precede flare-ups.

Preventing Future Scalp Issues
– Practice Good Hygiene: Regular hair washing (but not over-washing) keeps oil and sweat buildup at bay.
– Choose Breathable Fabrics: Opt for cotton hats or avoid tight headwear in hot weather.
– Educate About Sharing: Teach kids not to share combs, hats, or hair accessories to reduce lice risk.
– Patch Test New Products: Test shampoos or dyes on a small skin area before full use.
