If you have lice, there are a few things you can do to clean your brushes and get rid of the lice. First, use a mild soap. You can use a regular bar of soap or a shampoo bar specifically designed for cleaning hair. Soak the bristles of the brush in the soapy water for about 30 seconds. Rinse the brush well and dry it off. Next, put some rubbing alcohol on a cotton ball and swab around the base of each bristles. Be sure to get into all nooks and crannies. Finally, rinse off the alcohol with water and dry off your brush. These steps should be enough to get rid of most lice, but if you still have them after following these steps, you may need to go see a doctor. ..
