The Pro-Lice kit contains WipeOut(12oz) and the Pro-Lice Comb which work together to eradicate an active head lice infestation. WipeOut utilizes ingredients that destroy "Super Lice" without harming the individual. Since a louse can sense moisture and shut down its orifices, WipeOut is designed to keep those orifices open to kill the louse from the inside. After applying WipeOut, the Pro-Lice Comb removes deceased lice and their nits with steel, micro-grooved teeth. WipeOut is a professional product that will eliminate even the most difficult case of head lice.
