My best friend and her daughter keep getting headlice as soon as they are gone they are back again her daughter is 10 what can she do help

Recurrent lice: Recurrence of lice is the result of repeated exposure or chronic infestation due to incomplete nit removal (a tedious but essential task). Treating all family members at the same time. Over the counter lice kits have degree of toxicity when used repeatedly, and can result in resistance. A newer medication called Sklice touts the ability to kill both the louse and the nits, with low toxicity.

Head lice: It would be helpful to know where the reinfection is coming from. Ask the child to not use hairbrushes,or borrow hair accessories of others. Be sure bedding is washed in warm water and floors and furniture are cleaned. Also not all head lice treatments are effective and it may be time for a prescription.
