Nit Lice 101

 

Head lice are small brown and grayish insects about the size of a small sesame seed that you would usually find on a hamburger bun. You can find head lice clinging to a single strand of hair but they prefer to live close to the scalp because that is where they find their food. Head lice will hatch their eggs between 7 to 10 days. It also takes 7 to 10 days for a recently hatched louse to achieve adult hood and then start to lay its own eggs.

The majority of head lice infections will come from either close friends or family members. In most cases a person may not even be aware that they have an infectious group of head lice living on their scalp.

Most people that have head lice will not have any noticeable symptoms. The only symptom that may occur is an itchy scalp. An itchy scalp is not because of a head lice biting a person but rather it may occur because of an allergy. It will take approximately 2 to 3 months for any itching to develop after you have been infested with head lice.
