Lice infestations are not contagious after proper treatment. It's crucial to understand that lice are contagious only when there are adult female fertilized lice present. It is possible to eliminate all the adult lice while inadvertently leaving behind their small eggs, known as nits. This is why it is important to carefully comb the hair using a suitable nit comb or seek professional assistance. These nits remain dormant and hatch around 7 to 10 days later, leading many individuals to mistakenly believe they have been reinfected. In reality, the initial treatment was likely incomplete and thorough removal of the nits was necessary.
