It is possible to use head lice treatment on hair extensions, but you must be sure to remove the hair extensions before applying the treatment. This is because the chemical used to kill the lice will destroy the bonds in the hair extensions. However, the treatment does not harm the extensions themselves and you can reapply them afterward.
If you are unsure about whether you have head lice, it is best to visit a doctor who can show you the evidence. To identify lice, you should look for nits. These are colored brown and are visible when placed on a white napkin. Moreover, you should watch out for louses with their legs visible.
Head lice are parasitic insects that live on human scalps. Adult lice are about the size of a sesame seed, and are easily spread by head-to-head contact. In addition, head lice can be spread by sharing combs, pillows, and hats. Lice can survive for up to eight hours, but once they are removed from their food source, they will die. The louse life cycle starts with the nit, a small whitish-yellow speck that attaches itself to one hair strand.
Insecticides are a common way to treat head lice. However, they can be harmful to humans and the environment and may not be the most effective treatment. These products contain pesticides that damage the nervous system of the louse. The ingredients in these products kill the lice and their eggs. This method is only effective if you use the product correctly and make sure it has been applied thoroughly. It is also important to use only one product at a time. Using two or more products can result in reinfestation, which will require you to use another round of pesticides.
