Nits are not round, but oval. They are light-colored when first laid (yellowish or gray), but darken to a tan or coffee color as the embryo develops. Once the egg hatches, the spent shell (the nit) remains attached to the hair shaft, but it is white.
How do I get lice eggs out of hair?
Once the comb has run-through a section of hair, the comb should be cleaned off in a shallow bowl filled with water and dish soap. Then, wipe it dry using facial tissue or paper towel, being sure to remove any lice or nits that have clung to the comb. Repeat this process until you have combed through all of your hair.
Why are some lice eggs brown and some white?
Lice attach their nits to pieces of hair, close to the scalp. If you see a small, oval blob on a strand of hair, that’s probably a nit. If these little eggs are yellow, tan, or brown, the lice haven’t hatched yet. If the eggs are white or clear, the lice have hatched.
