What do nits look like on a comb

If you place a nit on a white paper towel and take a closer look, you will see that many nits are two-toned--often a golden brown with a dark brown circle inside.

When lice initially lay nits on the hair strand, they typically have this coloration.

The dark circle is the small lice bug growing inside the egg. Over the next few days, that lice bug grows inside the egg.

As it matures, the nit will appear darker and darker until it seems completely brown.

After the lice bug hatches out of the egg, the eggshell remains on the hair strand. Lice eggs left over after the bug has hatched will appear to be white or translucent because all you see left over is a shell or casing with no bug inside.

Similar to a chicken egg, after you crack open the egg and remove the insides, all you have left is a white shell.

Take a look at the close up picture of an old translucent lice eggshell. After the bug has left the egg, the top part of the eggshell is broken open, and you see only the shell.
