Check again: I would thouroughly check your head and hair again for any remaining lice or nits. Often, many of the treatments need to be repeated one week after initial treatment. Also, keep in mind that the shampoos used to treat lice can cause some irritation to the scalp which can induce itching and may not represent a residual lice infestation.
