Aside from severe itching of the scalp, the best way to tell if a lice infestation is present is to look for eggs stuck to the hair. If little cream colored eggs are in the hair NEAR THE SCALP SURFACE, this is a clear indication that live lice are present.
**Finding eggs in the hair is NOT an indication that there are living lice in the hair if the eggs are farther from the scalp surface (more than 1/2 inch away). These eggs either already hatched or are never going to hatch.
