Lice: What You Need to Know

Lice are tiny, wingless parasites that live on the human scalp. They feed on human blood and can cause intense itching and discomfort. Lice infestations, known as pediculosis, are especially common among school-aged children.

Life Cycle of Lice

  • Egg (Nit): Lice eggs, also known as nits, are laid by the female louse. They are oval and usually yellow to white. Nits are glued to the hair shafts and take about 7-10 days to hatch.

  • Nymph: The baby louse hatches from the nit and looks like an adult but is smaller. Nymphs mature into adults about 7 days after hatching.

  • Adult: Adult lice can live up to 30 days on a person's head. They feed on blood several times a day.

Symptoms of Lice Infestation

  • Intense itching: Caused by an allergic reaction to louse bites.

  • Red bumps on the scalp, neck, and shoulders.

  • Lice on the scalp: They might be hard to spot because they move quickly.

  • Nits on hair shafts: They can be mistaken for dandruff but are difficult to brush out.

Dandruff: An Overview

Dandruff is a common scalp condition that causes white flakes of skin to appear in the hair. It's not contagious or harmful, but it can be embarrassing and sometimes challenging to treat.

Causes of Dandruff

  • Dry skin: The most common cause of dandruff. Flakes from dry skin are generally smaller and less oily.

  • Seborrheic dermatitis: Marked by red, greasy skin covered with flaky white or yellow scales.

  • Not shampooing enough: Can lead to a buildup of oils and skin cells, causing dandruff.

  • Other skin conditions: Like eczema or psoriasis.

Dandruff vs. Dry Scalp

While dandruff and dry scalp might seem similar, they are different conditions. Dandruff is caused by an excess of oil on the scalp, leading to the buildup of skin cells that flake off. Dry scalp, on the other hand, is due to a lack of moisture, leading to irritation and flaking.

Spotting the Difference: Lice Eggs vs. Dandruff

One of the most common confusions is differentiating between lice eggs and dandruff. Here's how you can tell them apart:

  • Location

    • Lice Eggs (Nits): They are found close to the scalp, especially behind the ears and near the neckline.

    • Dandruff: Can appear anywhere on the scalp.

  • Appearance

    • Lice Eggs (Nits): Oval and often yellow or white. They are about the size of a pinhead.

    • Dandruff: White, flaky particles that can be of varying sizes.

  • Attachment

    • Lice Eggs (Nits): Firmly attached to the hair shaft and cannot be easily brushed off.

    • Dandruff: Can be easily shaken or brushed off the hair.


Lice Eggs (Nits): Require specific treatments to remove both the lice and their eggs. Dandruff: Can be treated with medicated shampoos and conditioners.

Prevention and Care

Preventing lice and dandruff requires different approaches:

  • For Lice

    • Avoid head-to-head contact.

    • Do not share personal items like combs, brushes, or hats.
