Pubic lice (lice infestation) can grow even if you shave your body hair. Pubic lice are caused by lack of hygiene in the pubic area or sexual misconduct. The hairy environment of the pubic area is more suitable for the growth and reproduction of pubic lice. Pubic lice bites and their excretions will cause irritation to the pubic skin, which mainly manifests as itching and stinging. Pubic lice mainly attach themselves to pubic hair, and when infected with pubic lice, all pubic hair must be removed in order to avoid recurrent infections. Although the chance of re-infection decreases after the pubic hair is shaved, pubic lice will lay their eggs near the roots of the hairs, which will hatch into adult bugs after a period of time, and when the pubic hair grows back, the symptoms of pubic lice disease will still appear. To treat pubic lice, it is not only necessary to remove pubic hair, disinfect and iron intimate clothing, but also need to use topical medication under the guidance of a doctor, and at the same time, husband and wife or sexual partners should be treated at the same time. It is recommended to go to the hospital in time for treatment or therapy after having pubic lice.
