I'm a grandma of 3 and have dealt with the lice plague numerous times. I've spent thousands of dollars over the decades on lice treatments. Then I discovered the mouthwash cure. Generic is fine. It works like a charm. I make sure that the eyes are covered, spray full strength amber mouthwash to soak the hair and cover the head with a plastic bag (using a hair tie to secure in the back). After two hours I rinse the hair and hten go through with a high quality metal nitcomb. Bugs are dead and nits are easier to remove. Best most effective treatment I've found!! I've done tons of research on the cons of this treatment and the best they can come up with is that its flammable, the kids might suffocate on the bag, and that the alchol may absorb into the scalp. Some of the perscriptions shampoos can cause brain damage if used too often. No open flames or smoking while treatment is in progress and watch them so they don't try to eat the bag. BE SURE not to let it get into the eyes.
