Head lice are 3mm in length when fully grown with a tan or grey color. They get to the hair roots on the head and suck blood from the human scalp. Lice cannot survive more than 24 hours without blood.
Scratching these bumps makes them sore and can lead to an infection. An infected bump will be red, tender, and you may have a scab on the scalp from head lice. Seek medical advice if you notice such bumps.
Head lice infestation
Head lice spread through head contact or sharing of personal effects used to groom hair. Note that pets like cats and dogs do not spread lice since lice cannot fly.
They are not an indication of poor hygiene. Kids mostly contract them from daycare or school and adults get it from friends or family members who share personal effects.
Black people are less prone to attacks by head lice as compared to other races because of their hair shaft shape that makes it difficult for head lice to grab onto. However, this does not mean that they cannot get them
Severe infestation
Some infestation may never itch. Itching occurs when the lice inject antigenic components from their saliva into your scalp when they feed. The itching can last for a period of 6 weeks on first infestation.
Severe head lice infestation involves more than 10 live lice on the head. This condition is called pediculosis.
If you neglect a head lice infestation it may lead to secondary infection on the scalp. However, head lice do not spread other diseases
Head lice eggs
Their eggs look like dandruff flakes and they are also known as nits. A female louse produces a sticky substance that makes nits stick on hair shafts. Lice bites are itchy red bumps on the scalp or neck.
Nits are tiny with brown, tan, white, or yellow shade. They look like dandruff and they can’t easily move even if you brush your hair or shake them off. The female louse produces a sticky substance that adheres to the hair shaft and scalp. They are easier to spot more than lice unless you have a chronic infestation.

However, the eggs of head lice look like dandruff the only difference is that the eggs do not fall off easily like dandruff.
Dandruff only itches when the scalp is super dry while head-lice infestation itch when the saliva of the lice irritates your scalp.
Head lice are contagious and can spread from one person’s head to another when they share personal hair grooming material. However, dandruff is not contagious.
Head lice are associated with red swollen bumps on the scalp while dandruff does not cause any inflammation. Dandruff mostly affects adolescents and young adults while head lice can infect anyone.
