There are a number of head lice treatments that you can buy over the counter. Some of these products work to kill lice, while others are just for prevention. Preventative products include sprays and shampoos. These products prevent lice from returning, and don’t require a second treatment. You should be sure to follow the directions carefully to ensure that your child’s scalp is safe.
In addition to applying an insecticide, you can also try nit combing. A pediatrician at Harvard Children’s Hospital recommends this method, which is nontoxic and does not have any side effects. She also recommends regularly checking everyone’s head and washing hair in hot water.
Another way to protect yourself against head lice is to keep your child away from other people with lice. While head lice can easily be spread from head to head, it is crucial to treat the lice as early as possible. Changing pillowcases and ensuring that they are dry and warm can help to prevent the spread of the disease.
If the live lice are still present after using a permethrin treatment, you should apply a second treatment. This is recommended if live lice are still visible seven to nine days after the first treatment. For the best results, you should use the product regularly to keep the lice from coming back.
