Key signs and symptoms to check
If your child keeps scratching head—especially at night—consider lice. An itchy scalp in a child can be caused by many things, but these signs point to lice:
- Persistent itching that worsens at night
- Red or irritated scalp from scratching
- Tickling feeling of something moving in hair
- Small sores or crusts on scalp from scratching
- Lice behind ears and at the nape of the neck (favorite hiding spots)
- White eggs in hair (nits) stuck to the hair shaft and hard to slide off
Live lice are quick and avoid light. Nits (eggs) are easier to spot because they’re glued to hair within about a quarter inch of the scalp.
Nits vs dandruff: what’s the difference?
Families in Denver frequently ask us about nits vs dandruff because both can look like tiny white specks. Here’s how to tell them apart if you’re seeing bugs in hair not dandruff or stubborn specks that won’t brush away.
| Feature | Lice/Nits | Dandruff |
|---|---|---|
| Location | Nits glued to hair shaft, often 1/8–1/4 inch from scalp; live lice move fast | Flakes on scalp and hair; not attached |
| Movement | Live lice crawl; nits do not move | No movement |
| Removal | Nits hard to slide off; need combing | Flakes brush off easily |
| Color | Nits are off-white/tan; hatched shells look white | White flakes; may be oily or dry |
If you see nits stuck to the hair shaft that don’t flick away, it’s likely lice—not dandruff.
Step-by-step: how to tell if you have lice
Use this at-home method to confirm lice quickly and accurately.
- Gather tools: bright natural light, a fine-tooth lice comb, paper towel, conditioner, and clips.
- Detangle dry hair, then apply a small amount of conditioner to reduce friction.
- Start at the nape and behind the ears—lice favor these warm spots.
- Comb from scalp to ends in small sections; wipe the comb on a white paper towel after each pass.
- Look for:
- Live lice: sesame-seed sized, tan/gray, fast-moving
- Nits: off-white/tan ovals cemented to hair; won’t slide off
- Repeat over the crown and sides until the entire scalp is checked.
If you’re unsure, snap a clear, well-lit photo of what you find and reach out—we’re happy to help you confirm. For complete removal, see our in-home lice and nit removal services.
Head lice on a toddler: special guidance
Head lice on toddler hair can be tricky because fine strands tangle and toddlers have limited patience. Avoid pesticide shampoos for little ones. Instead, rely on careful combing with a professional-grade comb and non-toxic conditioner. Our mobile head lice clinic team is trained to calm wiggly toddlers and complete safe, gentle removal at home.
What to do next (professional and at-home options)
If you’ve confirmed lice, act within 24–48 hours to prevent spreading. Here’s a simple plan.
At-home checklist
- Comb every strand daily for 7–10 days with a metal lice comb
- Focus on the scalp, nape, and behind the ears
- Wash pillowcases, hats, and brushes used in the last 24–48 hours
- Do not bag or spray your home—lice don’t live long off the head
- Schedule a re-check on day 7 to ensure all nits are gone
Pro tips for faster success
- Use plenty of conditioner during comb-outs; it slows lice and gathers debris.
- Section hair tightly and overlap your comb passes—missed sections are the #1 reason for recurrence.
- Clean the comb between swipes on a white towel to spot evidence clearly.
- Limit head-to-head contact until you have two clear checks 24 hours apart.

FAQ
How long after exposure will itching start?
Itching can start 4–6 weeks after the first case because it’s a reaction to bites. In repeat cases, itching may start sooner.
Can I get lice from my house or pet?
Lice need human blood and die within 24–48 hours off the head. Pets do not carry human head lice. Focus on heads, not the house.
Do over-the-counter shampoos work?
Many contain pesticides and may not kill resistant lice or remove nits. Manual combing by trained pros remains the most reliable approach.
How do I prevent spread at school or daycare?
Avoid head-to-head contact, keep hair tied back, and perform routine checks during outbreaks. Notify close contacts if a case is confirmed.
