All About Lice
Everything you need to know about head lice Lice cycle, how they spread, what symptoms to look for, and the best ways to treat and prevent them.
What Are Head Lice?
Head lice are tiny insects that live on the scalp and feed on small amounts of blood. They are very common among school-aged children but can affect anyone in close contact.
Size: About the size of a sesame seed
Color: White, gray, or brown
Lifecycle: Egg (nit) → Nymph → Adult
Quick Fact: Head lice do not spread diseases, but they can cause itching, discomfort, and stress for both children and adults.
At Bye Nits, we specialize in thorough lice and egg removal, while also teaching you the best ways to stay lice-free for good.
How Do Lice Spread?
Lice spread mainly through direct head-to-head contact. They cannot jump or fly, but they move quickly from one strand of hair to another when heads touch.
Common ways lice spread:
- Sharing hats, combs, hairbrushes, headphones, or towels.
- Using the same bedding, cushions, or furniture.
- Close contact during play, school, sports, or sleepovers.
- Did you know? Pets cannot get or spread human head lice.
To prevent lice from spreading, it’s important to avoid sharing personal items and to check all family members if one person is infested, especially in homes with children or home helpers and in environments like schools or daycare centres.
Step-by-Step Guide to Removal
Identify
Check the scalp carefully, especially behind the ears and near the neck, where lice and eggs often hide.
Comb Out
Use a fine-tooth lice comb on damp hair to remove lice and nits from root to tip.
Treat
Apply a professional lice treatment or visit Bye Nits for a full in-salon session to ensure all lice and eggs are removed.
Clean
Wash bedding, clothes, towels, and combs in hot water to prevent reinfestation.
Repeat & Monitor:
Recheck hair after 7 days to make sure no new lice have hatched. A quick follow-up helps keep the whole family lice-free.
Symptoms to Look Out For
Constant itching
Red bumps
Visible nits
Tickling
The life cycle of lice lasts about 30 days and includes three stages: eggs (nits), nymphs, and adults.
Each stage plays an important role in how lice survive and spread.
Egg (Nit)
Laid close to the scalp, nits are glued firmly to the hair shaft. They hatch in about 7–10 days, leaving behind a translucent shell.
Nymph
Once hatched, the baby louse (nymph) begins feeding on blood immediately and matures within 9 days through three growth phases.
Adult
Fully grown lice live for about 3 weeks, laying up to 10 eggs per day. Without a human host, they survive only 24–48 hours.
Because of this short but rapid life cycle, even one missed egg can restart the infestation , which is why a 7-day follow-up check is essential at Bye Nits.
Survival & Transmission
Lice have adapted perfectly to human scalps:
- They feed every few hours and cannot survive long without human blood.
- Their eggs are glued so tightly to the hair that home treatments often fail to remove them completely.
Lice do not jump or fly, but they crawl quickly from head to head especially when:
- Kids play closely or share selfies and hugs
- Families or home helpers share brushes, pillows, towels, sofa, or car
- Children/parent sit or sleep side by side
This is why checking everyone in the same home and time is crucial when one case appears – including parents and caregivers.
At Bye Nits, we understand how easily lice spread and ensure every nit is gone, breaking the cycle safely and completely.

FAQ's
1. What are head lice and how do they live?
Head lice are small insects that live on the scalp and feed on blood. They can’t jump or fly but crawl quickly between hair strands. Each louse lives for about 30 days and lays eggs (nits) close to the scalp.
2. How can I tell if my child has lice?
The most common signs are constant itching, red bumps on the scalp, and visible nits near the roots of the hair. You might also see tiny moving lice, especially behind the ears and near the neck.
3. Can lice spread through sharing items like hats or towels?
Yes. Lice often spread through shared personal items like hats, hairbrushes, combs, pillows, or headphones. It’s important to avoid sharing anything that touches the hair or scalp.
4. Can pets carry or spread lice?
No. Human head lice only live on humans — pets cannot get or transmit lice.
5. How long can lice survive off the head?
Lice can only survive for 1–2 days away from the scalp. However, nits (eggs) can remain attached to hair strands even after lice die, so proper combing and cleaning are essential.
6. What’s the best way to remove lice at home?
Wet combing with a fine-tooth lice comb is effective. However, for complete removal of lice and eggs, a professional treatment — like Bye Nits’ non-toxic, in-salon procedure — ensures faster and safer results.
7. How can I prevent lice from coming back?
Check the whole family at the same time, clean bedding and brushes in hot water, and schedule regular scalp checks. Using lice-repellent essential oils and routine combing can also help prevent reinfestation.
8. How often should I recheck after a treatment?
We recommend rechecking 7–10 days after treatment to ensure no new lice have hatched. At Bye Nits, we include a free follow-up check to guarantee your family stays lice-free.
