The lice & eggs removal machine uses the comb and suction power to gently lift lice and eggs. The teeth are rounded to smoothly run across the head. The comb head has been designed to adjust to either a rake or comb position for maximum comfort depending on the length of the hair. The design is smooth and rounded so that there are no sharp edges or components. As you gently comb through the hair, lice & eggs removing the machine's disposable capture filters securely traps head lice and their eggs. This makes rechecking the hair easy and reduces the chances of infestation. A brush is supplied with the unit to clean the stainless steel comb and unit between users. After each treatment, simply remove the disposable capture filter, snap on the lid, and hygienically dispose of the used filter.
