The female head louse lays as many as 10 eggs (ova) per 24 hours, usually at night. She positions her eggs at the base of the hair shaft within 1-2 mm of the scalp, with a predilection for the hair line at the back of the neck and the backs of the ears. These eggs may appear to be dandruff flakes except they are adherent to the hairs and cannot be shaken off.

The entire scalp is usually itchy, but the rash is preferentially located at the back of the neck and/or ears. The rash frequently looks for all the world like eczema that has been scratched.

Treatment of head lice involves shampooing your hair with a lice shampoo, such as permethrin shampoo. The recommended number of treatments is one, however I found that with my patients, we need 5-7 consecutive days of treatment to kill all the lice. You also need to get a lice comb and comb out all the eggs from the hair.

I recommend that all members of the household get treated at the same time to make sure there are no residual lice in the house. All the combs, brushes and hats need to be washed with hot soapy water.
I also recommend an evaluation by a dermatologist or your regular doctor to make sure this is the proper diagnosis. Also, please make sure you don’t have any allergies or sensitivities to the ingredients of the shampoo.
