Nits are tiny oval-shaped eggs that firmly attach to the hair shafts usually within ½ – 1 inches of the scalp. They may be off-white to brown in color. Unlike dandruff, they will not brush or blow off the hair. Not everything that doesn’t move easily off the hair shaft is a nit. Look at the hair and whatever is attached to it while it is taped on the white paper.
