This has got to be one of the most disgusting videos I've ever watched. I don't know how this young girl acquired such a bad case of lice, but I was floored when I saw how much lice this woman was combing out of her hair. There are layers upon layers of lice sticking to the comb every time it's pulled through her short locks. Have you ever had lice or seen a case this bad? 
According to the Mayo Clinic, head lice are small, wingless, parasitic insects that feed on your blood. As seen in this case of lice, they develop on the scalp, and are easiest seen at the nape of the neck and over the ears. Head lice live for approximately 30 days, and the females lay nearly six eggs a day, causing the multiplication of lice to be particularly rapid. In this video, it's hard to say how long the young girl has had lice as sometimes it takes up to three months for itchiness to develop. One thing's for sure: she has accrued a ton of the tiny insects! 

Because lice are so easily spread, it's important to know how to get rid of it. Lice can be treated with special lotions and shampoos designed for repeated use in the case of head lice. After using a shampoo treatment it is best to rinse the hair with vinegar to help remove nits from the hair shaft. Cutting the hair short is also a good way to help the process of lice removal. Using a fine-toothed comb like the one in this video will remove the actual nits from the hair, but must be performed every three to four days for at least two weeks; hair must be wet for this to work. Above all, it is important to wash everything that could be contaminated by the person carrying the lice. From bedding and clothes, to brushes and toys, anything that could have lice on it should be washed with hot water and dried on high heat. Vacuuming and covering furniture are also important steps to take to prevent the spread of lice.
