Baby skin is sensitive and changes frequently. If you are noticing scalp ringworm (tinea capitis) in baby, here is what you need to know.
The short answer
Tinea capitis (scalp ringworm) is a fungal infection of the scalp that causes scaly patches, itching, and areas of hair loss. Unlike ringworm on the body, scalp ringworm requires oral antifungal medication because topical creams cannot penetrate the hair follicle adequately. The hair typically grows back fully after successful treatment.

What Parents Should Know
According to AAP, AAD, NIH guidelines, tinea capitis (scalp ringworm) is a fungal infection of the scalp that causes scaly patches, itching, and areas of hair loss. Unlike ringworm on the body, scalp ringworm requires oral antifungal medication because topical creams cannot penetrate the hair follicle adequately. The hair typically grows back fully after successful treatment. At 0-3 months, tinea capitis is rare in newborns but possible. Scaly scalp patches at this age are more commonly cradle cap. If scalp patches are accompanied by hair loss or the area looks inflamed, your pediatrician should evaluate to rule out a fungal infection. A fungal culture can confirm the diagnosis. It is generally considered normal when cradle cap (seborrheic dermatitis) is often confused with tinea capitis but does not cause hair loss. However, you should contact your pediatrician promptly if a swollen, boggy, tender area on the scalp (kerion) that may ooze or be very painful.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Tinea capitis is rare in newborns but possible. Scaly scalp patches at this age are more commonly cradle cap. If scalp patches are accompanied by hair loss or the area looks inflamed, your pediatrician should evaluate to rule out a fungal infection. A fungal culture can confirm the diagnosis.
3-6 months
If tinea capitis is suspected, a culture of the affected scalp area confirms the diagnosis. Treatment with oral antifungal medication (usually griseofulvin) is necessary and is safe for infants under medical supervision. A medicated selenium sulfide or ketoconazole shampoo used 2 to 3 times weekly helps reduce contagiousness.
6-12 months
Tinea capitis becomes more common as babies have more social contact. Signs include round patches of hair loss with black dots (broken-off hairs), scaling, and sometimes swollen, boggy areas called kerions. Treatment typically lasts 6 to 8 weeks. All family members should use antifungal shampoo to prevent spread.
12-24 months
Toddlers in daycare are at higher risk. Do not share combs, brushes, hats, or hair accessories. A kerion (severely inflamed, swollen area) may need additional treatment with oral steroids alongside antifungals. Complete the full course of medication even if the scalp looks better before treatment ends.
What to Tell Your Pediatrician
- Describe when you first noticed scalp ringworm (tinea capitis) in baby and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if scaly patches on the scalp with associated hair loss.
- Mention if a round bald spot on your baby's scalp.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Cradle cap (seborrheic dermatitis) is often confused with tinea capitis but does not cause hair loss
- Scaly patches on the scalp with associated hair loss
- A round bald spot on your baby's scalp
- Scalp itching that is not responding to cradle cap treatments
- A swollen, boggy, tender area on the scalp (kerion) that may ooze or be very painful
- Scalp infection with fever and enlarged lymph nodes in the neck

What You Can Do at Home
- Keep track of when you notice scalp ringworm (tinea capitis) in baby — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that cradle cap (seborrheic dermatitis) is often confused with tinea capitis but does not cause hair loss — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
- While monitoring at home, seek immediate care if a swollen, boggy, tender area on the scalp (kerion) that may ooze or be very painful.
Related Conditions
Treating Ringworm in Baby
Ringworm (tinea) is a common fungal infection that causes a ring-shaped, scaly rash. It is treated with over-the-counter antifungal cream applied twice daily for 2 to 4 weeks, even after the rash looks better. Ringworm is contagious but your child can return to daycare once treatment has started. It is not caused by a worm despite the name.
Patchy Hair Loss in Baby
Patchy hair loss in babies is usually caused by friction from lying on the back (positional alopecia), a very common and harmless condition. Other causes include alopecia areata, scalp ringworm, or cradle cap. Positional hair loss fills in naturally as the baby spends more time sitting up.
Cradle Cap (Seborrheic Dermatitis)
Cradle cap is a very common, harmless condition that causes yellowish, greasy, scaly patches on your baby's scalp. It is not caused by poor hygiene, it does not bother your baby, and it almost always clears up on its own within the first several months of life.
Alopecia Areata in Babies
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing round, smooth patches of hair loss. While uncommon in babies, it can occur at any age. The condition is not painful or contagious. Many children experience spontaneous hair regrowth, though it may take months. Your pediatrician or dermatologist can confirm the diagnosis.

My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
