Yes, babies can get head lice, though it’s uncommon in children under two years old. Infants simply have less hair and fewer opportunities for the head-to-head contact that spreads lice. When it does happen, treatment options are more limited because most lice products aren’t approved for very young children, making manual removal the primary approach.
How Babies Get Lice
Head lice spread almost exclusively through direct head-to-head contact. For a baby, that typically means prolonged contact with a parent, sibling, or caregiver who already has lice. Cuddling, co-sleeping, and carrying an infant against your head or neck all create the kind of close contact lice need to crawl from one person to another.
Sharing items like hats, hairbrushes, or pillowcases is a much less likely route. Lice need a blood meal every 12 to 24 hours and can’t survive away from a human head for longer than a day. That said, if an older sibling in the household has lice, it’s worth checking the baby, since families tend to share close physical space constantly.
How to Check Your Baby’s Scalp
Spotting lice on an infant can be tricky, especially because cradle cap and dry skin flakes are common at the same age. Here’s what to look for:
- Live lice: Dark, poppyseed-sized insects crawling on the scalp, especially along the part line or behind the ears.
- Nits (eggs): White or yellowish-brown specks glued to the hair shaft, typically within a quarter inch of the scalp.
The simplest way to tell nits apart from dandruff or cradle cap flakes is to try flicking the speck off the hair. Dandruff slides off easily. Nits are cemented to the shaft and won’t budge without deliberate pulling or a fine-toothed comb. Work under a bright light and part the hair in small sections to get a clear view.
Babies can’t tell you their head itches, so watch for unusual fussiness, frequent head rubbing, or disrupted sleep. Some infants show no obvious signs at all, and the infestation is only discovered when a family member is diagnosed.
Why Treatment Is Different for Babies
Most over-the-counter lice shampoos and lotions carry age restrictions that put them off-limits for young infants. Here’s a general breakdown of when common treatments become an option:
- Two months and older: Certain prescription topical creams containing permethrin (5%) are FDA-approved starting at two months, but these are formulated for scabies, not lice. The over-the-counter permethrin rinse (1%) used for lice is generally labeled for children two years and older.
- Six months and older: Two prescription options become available. One is a single-application lotion (ivermectin 0.5%) that kills live lice and prevents newly hatched lice from surviving, often without requiring nit combing. The other is a prescription suspension (spinosad) initially approved for ages four and up, later expanded to six months and older.
For babies younger than six months, no medicated lice treatment is FDA-approved. That leaves manual removal as the safest and most practical option.
Wet Combing: Step by Step
Wet combing is the go-to method for babies too young for chemical treatments, and it works well given how little hair most infants have. You’ll need a fine-toothed nit comb (metal ones work best), a regular comb or soft brush, a spray bottle of water, a white towel, and a bowl of warm soapy water.
Start by wetting your baby’s hair and gently working out any tangles with a regular comb. Drape a white towel over their shoulders so you can see any lice that fall. Then take the nit comb and run it through small sections of hair, starting as close to the scalp as possible and pulling all the way to the tips. Comb each section several times before moving on. For babies with very short hair, sectioning isn’t necessary. Instead, comb the hair to the right, then to the left, then from back to front, repeating several times.
After each pass, rinse the comb in the bowl of soapy water and wipe it on a paper towel to remove any lice or nits. When you’re finished, soak the comb in water hotter than 130°F for five to ten minutes. Wash the towel in hot water and dry it on a high heat setting.
The key to making wet combing work is consistency. Repeat the process every other day for two full weeks. This catches any nits you missed and removes newly hatched lice before they’re old enough to lay eggs themselves. A single session won’t resolve an infestation because eggs take about a week to hatch.
Cleaning Baby Gear
Because lice can only survive one to two days without a host, you don’t need to deep-clean your entire house. Focus on items that have been in direct contact with your baby’s head in the past 48 hours.
Wash crib sheets, blankets, hats, and any fabric headrests in hot water and dry them on high heat. Vacuum your car seat, stroller, and any upholstered furniture where your baby has been sitting or lying. Items that can’t be washed or vacuumed (like a stuffed animal your baby sleeps with) can be sealed in a plastic bag for two weeks. After that period, any lice or viable nits will be dead.
There’s no need to spray furniture or rooms with insecticide. Transmission from objects is rare, and the chemicals pose more risk to a baby than the lice themselves.
What to Watch For
Head lice don’t carry diseases, but persistent scratching can break the skin on your baby’s scalp. Those small wounds sometimes become infected with bacteria that are normally harmless on the skin’s surface, leading to red, crusty, or oozing sores. If you notice signs of infection, or if your baby develops a fever alongside scalp irritation, that warrants medical attention.
Irritability and poor sleep are the most common effects of lice in infants. These typically resolve quickly once the lice are cleared. If you’ve been combing diligently for two weeks and are still finding live lice, talk to your pediatrician about whether a prescription treatment is appropriate for your baby’s age.
