If there are lice in the pubic hair, the condition is clinically known as pubic lice. Lice are parasites that grow on the pubic hair and cause intense itching and the presence of eggs on the pubic hair, and are mostly caused by a history of high-risk sex, a condition known as a sexually transmitted disease (STD). It is recommended to shave off all pubic hair and burn the shaved pubic hair to avoid spreading the disease to others. After shaving the pubic hair, wash the vulva, and then apply iodine on the pubic mound for treatment. It is recommended that the iodine applied should not flow onto the labia, so as not to cause localized tingling. Generally, this condition will be cured after about 5-7 days of clinical treatment. It is recommended that in addition to keeping the vulva clean, women must also avoid a history of high-risk sex in their daily lives.
