Signs and Symptoms

Head lice can cause itching and scratching especially on areas of the body with hair.  They particularly love the scalp, behind the ears and the nape of the neck.

You can often see the lice eggs, also known as nits on the hair shaft.  They look like tiny white little grains of sand and can often be mistaken for dandruff. 

The difference between dandruff and nits is dandruff flakes off whereas nits literally stick to the hair shaft and will not move if you blow on them.

When checking a head, chances are you will not see the lice because they are very fast moving.  You will however see the nits and that is what you should be looking for to determine if you have an infestation.
