Mayonnaise
While mayonnaise is a great ingredient for your salad, it can also be used to get rid of lice effectively. It is recommended to spread this substance over the whole scalp, then cover the area with a shower cap. Leave it overnight so that the lice would suffocate. In the morning, use a comb to remove dead nits and lice on your hair, then wash thoroughly to cut through its grease. Keep in mind to use full-fat, real mayonnaise to get the best results. Do it 1 week later to remove any lice which survives the previous treatment. [2]
