Because lice are tiny and easy to miss, many people feel unsure at the beginning. So, to remove confusion and worry, let’s clearly explain what lice look like in the simplest, most honest way.

What Lice Look Like (Plain Explanation)

Lice are very small parasitic insects that live on the scalp and feed on blood.

Visually, lice usually look like:

• tiny bugs, similar to a sesame seed
• tan, gray, or light brown in color
• flat before feeding, rounder after feeding
• fast-moving when disturbed
• wingless and crawling, not jumping

Because they blend into hair easily, spotting them takes patience.

Bold Summary: Lice are tiny, crawling insects near the scalp that resemble small brown or gray sesame seeds.

What Lice Eggs (Nits) Look Like

Often, people see nits before seeing live lice.

Nits usually look like:

• tiny white, yellow, or tan dots
• oval or teardrop shaped
• firmly attached to hair strands
• located close to the scalp
• difficult to slide off

Because dandruff flakes move easily, while nits stay stuck, this difference matters.

Where Lice Are Most Commonly Found

Lice prefer warm, hidden areas. Therefore, they are commonly found:

• behind the ears
• at the nape of the neck
• along the scalp line
• under thick hair sections

Because of this, careful checking is essential.
