Head lice are small insects that can be difficult to spot in your hair.
The eggs which are commonly know as “nits” are brown or white empty shells attached to the hair by a sticky substance.
The Lice will hang onto the hair tightly remaining close to the
scalp where it is warm; can get food (your blood); and are able
to hide, making it difficult to see them. It is the adult lice that will
move from head to head when in close contact. The nymph or
younger lice stay on the same head for around six days after hatching.
