What You Need

What To Do

  1. Wash your hair with a clarifying shampoo to remove any product residue from your hair. This step is critical as the residue may otherwise reduce the effectiveness of olive oil.
  2. Liberally apply olive oil to your hair and scalp. Dividing your hair into several sections can ease this process.
  3. Tie your hair into a bun and put on your shower cap. Ensure the elastic of the shower cap is tight enough to let it sit securely on your head (to keep the lice from escaping).
  4. Leave the shower cap on for 4 to 6 hours.
  5. Remove the shower cap and comb the lice out with a nit removal comb. Clean the comb with paper towels at regular intervals. Dispose the paper towels once you are done.
  6. Wash and shampoo your hair twice after you are done.
  7. Divide your hair into sections and blow-dry close to the scalp on medium heat. This will kill the nits.
  8. Follow this routine 2 to 3 times a week until your hair is free from head lice.
