How Can Head Lice Change Colour?

Head lice are tiny, brown insects with six legs. Adult lice are about the size of a sesame seed. As their blood oxidises, their colour changes to black. Luckily, these lice are not harmful to humans and the best way to get rid of them is to treat them as soon as possible. You should check your hair regularly for signs of head lice and make sure that you don’t have any new infestations.

Adult head lice are two to three millimeters long and tan to gray-white in colour. They have six legs and can latch onto hair. When stuck on a human head, they will live for up to 30 days before dying. If they fall off their host, they’ll die within one or two days.

Head lice are not dangerous to humans, but they can cause an itchy scalp. If you have a head lice infestation, you should visit a doctor and take the proper medication. You should avoid contacting other people and stay away from school until you are sure that you’re free of the parasite.

Hair dye is not a solution for head lice, but it can help treat them. However, you should read the ingredients label and only use products with hydrogen peroxide or ammonia. These products will help kill live lice while also discolouring the hair.
