Mayonnaise has been known to kill lice in some cases and if you are looking for a natural way to do this it will be important to know how to go about applying it. You will need to cover your head in a thick coat of mayonnaise so that all of it is completely covered for maximum effectiveness. You will then want to put a shower cap over your head and keep all of the mayonnaise on your hair for anywhere from six to eight hours. It is extremely important to make sure that you keep the mayonnaise on your hair for a long time in order to ensure that all of the lice are killed.
You may want to leave the mayonnaise on your hair overnight just so you can increase the likelihood of this treatment working. After you have left the mayonnaise on your head for a long enough time you will need to take of the shower cap and massage shampoo through your hair until you have completely removed all of the mayonnaise. As you are washing out the mayo you should be able to see the dead lice going down the drain. It will be important to make sure that you remove and thoroughly wash all of the linens as well as any stuffed animals in order to make sure that none of the lice are left behind to reproduce.
