An itchy scalp is the most common symptom of lice infestation. However, other conditions, including dandruff and scalp eczema, can cause also itchy scalp. Itchy scalps can also be a sign of an allergic reaction to hair care products such as shampoo, too.  Some people who have head lice may not experience itching right away. It can take up to six weeks after infestation for the scalp to begin feeling itchy.  Some people may also feel a “tickling” sensation on their scalp or head, as though something is moving or crawling. White flakes may be caused by dandruff or scalp eczema. They may also be caused by an allergic reaction to shampoos and other hair care products. However, these “flakes” may actually be lice eggs (nits).  Dandruff commonly occurs throughout the hair. Lice eggs commonly occur closer to the scalp and are not as widespread as dandruff flakes. If you cannot easily brush or shake the flakes off the hair or scalp, they may be lice eggs. Lice may find their way into your home on clothes or bedding. They cannot fly, but they can jump great distances. You may see small bugs that look like light-brown sesame seeds on clothing, bedding, skin, or hair.
