Lice Treatment begins with explaining to the parents and children how lice spreads. If you aren't taught how it spreads how are you going to avoid catching head lice again? Licenders takes the time to talk to you, to explain step by step what you need to do and what you don't. Kids socialize in a different fashion then adults do.
