Abstract
A shampoo/conditioner that repels lice and aids in the removal of head lice and nits is presented. It is a formulation comprising at least one homeopathic louse insecticide included with acetic acid in association with a gentle wetting agent and shampoo and conditioner and softener components, all tested for low dermal irritation with a final pH below 4.5 and a viscosity of 1200 to 2000 CPS. The product reduces or eliminates the activity of live lice and makes it significantly easier to comb out nits. The product creates an environment repulsive to head lice thereby acting to prevent re-infestation. It is suited for the daily use that is necessary to insure permanent removal of all lice and nits by combing and serves to beautify the hair.
