Also to know is, what color are live lice eggs?
Nits often appear yellow or white although live nits sometimes appear to be the same color as the hair of the infested person. Nits are often confused with dandruff, scabs, or hair spray droplets. Head lice nits usually take about 8–9 days to hatch.
One may also ask, do dead nits stick to hair? Head lice are not spread through bed linen, clothing or head gear, as they do not leave the scalp unless they are dead or dying. Eggs ('nits') do not fall off until weeks after they have hatched as the egg shells are glued tightly to the hair shaft.
