Lice vs Dandruff: How to Tell the Difference
Confused about whether those white specks are lice eggs or just dandruff? Learn the key differences so you can identify what you're dealing with and take the right action.
The Quick Test
Try to brush or blow the white specks off the hair shaft:
If they come off easily: It's likely dandruff
If they won't budge: It's likely lice eggs (nits)
Key Differences at a Glance
While both lice nits and dandruff can appear as white specks in hair, they have very different characteristics. Here's how to tell them apart:
Appearance
Lice (Nits)
Nits are small, oval-shaped, and firmly attached to individual hair strands. White, tan, or yellowish in color.
Dandruff
Irregular white or yellowish flakes of varying sizes. Loose and easily moved.
Attachment
Lice (Nits)
Nits are glued firmly to the hair shaft and won't brush or blow off. Require force to remove.
Dandruff
Flakes sit loosely on scalp and hair. Easily brushed, blown, or shaken off.
Location
Lice (Nits)
Nits usually within 1/4 inch of scalp, concentrated behind ears and at nape of neck.
Dandruff
Scattered throughout hair and on shoulders. Falls onto clothing easily.
Texture
Lice (Nits)
Hard shell-like eggs with smooth surface. Teardrop shape. Won't crush easily.
Dandruff
Soft, flaky dead skin cells. Irregular shapes. Crumbles when rubbed.
