Symptoms
Hie most common symptom is itching of the scalp, caused when the louse bites through the skin to
feed on blood. Other symptoms include irritation caused by the louse's saliva, insomnia, adenopathy, hair loss
in massive infestations and psychological disturbs(mainly because of the associated stereotype), also
excessive scratching may cause bleeding of the scalp, which may increase the risk of microbial infection.

Treatments proven by medical research Shaying the Head
Shaving off all the hair is a viable solution.[2] This can be performed alone using mirrors to see all
sides of the head, although it is easier to have someone else help with the procedure. A completely shaven
head is not necessary, the hair only needs to be cut to 1 inch or less.
Shaving the head gives the lice little to grasp to stay attached to the head. The main reason for
cutting is to lower the temperature of the scalp. Lice primarily stay in the areas of hair that are warm and dark.
Girls generally have longer hair and you will find that the lice stay at the base of a ponytail, nape of the neck,
or behind the ears. Cutting the hair very short will cause an insufficient ambient temperature for lice to live in.
While effective, some patients may find the hair removal aesthetically unappealing which is why many turn to
other cures, typically requiring some form of chemical to be applied.
