The only way to guarantee that you will NEVER get lice is to shave your head COMPLETELY BALD. Any amount of hair (even the shortest buzz cut) is enough hair for lice to nest in. To minimize your exposure, never share brushes, hair accessories, hats, pillows, or sports helmets with others. Girls should wear their hair in a tight bun to keep it from touching other people’s heads. Using a lot of hair products like gel, mousse and hair spray are NOT effective at repelling lice. However, our Lice Choice Head Spray is gentle enough for you to use daily to help prevent lice. If sprayed daily on your hair, the Head Spray will immediately start breaking down the exoskeleton of any bug that has transferred onto your head, so it can’t mate and lay eggs. There are many lice “repellents” on the market that claim to discourage lice from wanting to go on your head because they won’t like the smell of the coconut, rosemary, peppermint, tea tree, etc. However, there is no scientific evidence that lice truly are repelled by these scents. And in our treatment facility, we have treated thousands of families who had been using these so-called “repellents” when they got lice.
