Is alcohol the best way to get rid of head lice you have tried shampoo and they keep coming back?

No, alcohol is not the best way to get rid of head lice. While alcohol can kill lice, it is not effective in removing nits, which are the eggs of lice. Nits are very small and can be difficult to see, but they are essential to get rid of in order to completely eliminate lice. If you have tried shampoo and lice keep coming back, it's important to use a treatment specifically designed for lice, such as a lice comb, over-the-counter lice medication, or prescription lice medication. These treatments are more effective in killing both lice and nits, and can help you get rid of lice completely.
