Understanding Those Mysterious Bumps on Your Child’s Scalp
As a parent, noticing unusual bumps on your child’s scalp can be alarming. Your mind might race through possibilities—Is it an infection? An allergic reaction? Something more serious? While it’s natural to worry, most scalp bumps in children are harmless and easily treatable. Let’s break down the common causes, how to identify them, and what steps you can take to help your little one feel better.

1. Folliculitis: Tiny Red or White Bumps
Folliculitis occurs when hair follicles become inflamed, often due to bacteria, fungi, or irritation. It’s common in kids who sweat heavily, wear tight hats, or scratch their scalps (hello, sandbox adventures!).
What to look for:
– Small red bumps or pustules, sometimes with a white tip.
– Mild itching or tenderness.
– Occasional crusting if scratched.
What to do:
– Keep the scalp clean with a gentle, fragrance-free shampoo.
– Avoid picking or scratching the bumps.
– For persistent cases, a pediatrician may recommend an antibacterial or antifungal shampoo.

2. Cradle Cap (Seborrheic Dermatitis): Flaky, Scaly Patches
Common in infants but possible in older kids, cradle cap is a harmless condition caused by overactive oil glands. It often appears as greasy yellow or white scales or crusty patches.
What to look for:
– Thick, flaky scales stuck to the scalp.
– Mild redness but no significant discomfort.
– Possible spread to eyebrows or behind the ears.
What to do:
– Gently massage baby oil or coconut oil into the scalp to loosen scales.
– Use a soft brush to remove flakes after bathing.
– For stubborn cases, a pediatrician might suggest medicated shampoos with salicylic acid or ketoconazole.

3. Head Lice: Itchy, Moving Specks
The mere mention of lice can make anyone’s head itch! These tiny parasites feed on blood and lay eggs (nits) close to the scalp. While not dangerous, they’re highly contagious.
What to look for:
– Intense itching, especially behind the ears or at the nape of the neck.
– Visible white nits (egg casings) glued to hair shafts.
– Small red bumps from scratching.
What to do:
– Use an over-the-counter lice treatment containing permethrin or dimethicone.
– Comb hair with a fine-toothed nit comb daily for 1–2 weeks.
– Wash bedding, hats, and brushes in hot water to prevent reinfestation.

4. Allergic Reactions or Contact Dermatitis
Kids’ scalps can react to shampoos, dyes, or even new laundry detergents. Contact dermatitis causes red, itchy bumps that may blister or ooze in severe cases.
What to look for:
– Sudden rash after using a new product.
– Swelling, dryness, or hives.
– Itching that worsens with scratching.
What to do:
– Identify and eliminate the irritant (switch to hypoallergenic products).
– Apply a cool compress or hydrocortisone cream (for children over age 2) to reduce inflammation.
– Antihistamines like children’s Benadryl can ease itching (consult a doctor first).

5. Scalp Psoriasis or Eczema: Chronic Dryness
While less common in kids, these chronic skin conditions can cause raised, scaly patches. Psoriasis often has well-defined red plaques with silvery scales, while eczema appears as dry, cracked skin.
What to look for:
– Persistent red or pink patches.
– Flaking that resembles dandruff but thicker.
– Itching that disrupts sleep or daily activities.
What to do:
– Use moisturizers designed for sensitive skin.
– Avoid harsh shampoos; opt for formulas with colloidal oatmeal or ceramides.
– A pediatric dermatologist may prescribe topical steroids or calcineurin inhibitors.

6. Insect Bites or Stings
Mosquitoes, fleas, or even spiders can leave behind itchy bumps. These are usually isolated and resolve within a few days.
What to look for:
– Single or clustered red bumps.
– A small puncture mark in the center.
– Swelling that subsides within 24–48 hours.
What to do:
– Clean the area with soap and water.
– Apply calamine lotion or a baking soda paste to reduce itching.
– Watch for signs of an allergic reaction (e.g., difficulty breathing), which requires immediate medical attention.
—
7. Cysts or Epidermoid Cysts
These slow-growing, painless lumps under the skin result from blocked hair follicles. While usually harmless, they can become infected if irritated.
What to look for:
– A small, firm bump that moves slightly when touched.
– No redness unless infected.
– Possible discharge of thick, cheese-like material if ruptured.
What to do:
– Avoid squeezing or poking the cyst.
– Warm compresses can reduce swelling.
– A doctor may drain or remove it if it causes discomfort.

When to Call the Doctor
Most scalp bumps resolve with home care, but seek medical advice if your child has:
– Severe pain, swelling, or warmth around the area.
– Fever or swollen lymph nodes.
– Bumps that ooze pus or bleed.
– No improvement after 1–2 weeks of treatment.
