Lice are tiny insects that live on the scalp and feed off human hosts. They breed and lay eggs, or nits, along strands of hair. They do not carry disease, but are highly contagious and cause itching. Lice spread from person to person through close contact. These tiny insects can live 30 days on the human body, while nits live two weeks or longer. Nits are often hard to get rid of, but there is a natural way to dry nits up and remove them from hair.
Apply two cups of olive oil to the hair from roots to tips. Leave the olive oil in.
Pour a cup of salt onto the hair. The olive oil helps the salt to stick to the strands of hair. Using your fingers, make sure the salt is evenly spread on every strand of hair. The salt will dry up nits that remain on the hair strands.
Wrap the hair up in a plastic bag and let it sit for 8 hours.
Rinse the hair with warm water and then comb the hair with a fine-tooth comb. Wipe the comb on a towel to get rid of dead nits. Repeat until all the hair is thoroughly combed.
