How can you remove head bugs in one day?

To remove head lice in one day, start by using a fine-toothed lice comb on damp hair to physically remove lice and nits. Follow up with an over-the-counter pediculicide shampoo or treatment specifically designed to kill lice. After treatment, wash all bedding, hats, and personal items in hot water, and vacuum areas where the infested person has been. Finally, check and treat all household members to prevent re-infestation.
