Head Lice and Nits

Two Different Things

Live head lice are moving insects on the scalp. Nits are the eggs, and they are firmly attached to individual hair strands, usually close to the scalp.

Nits do not brush off the way dandruff, hairspray residue or dry skin will. That resistance is often the clearest clue.

Why It Matters

Missing nits is the most common reason a case comes back. Removal has to account for both the live head lice and the eggs, strand by strand.
