Q. About ten years ago our daughter did her practice teaching in an elementary school and got head lice. We tried all the treatments, but the lice kept coming back.
She finally found an electronic comb (Robi Comb) that electrocutes the lice. It was a bit pricey, but not as much as multiple bottles of lice shampoo that didn’t work.
A. We have heard from many frustrated parents that standard lice shampoos frequently fail because lice have become resistant to the pesticides. A dermatologist described his own success with Robi Comb in a similar situation (Journal of the American Academy of Dermatology, Feb. 2005).
The Robi Comb uses electric current to kill lice, but it does not shock the person on whom it is used. Daily use for two weeks is required to zap the lice and remove the nits. After that time, using it a few times a week for a month can help prevent the re-infestation that so troubled your daughter.
