text: how do you get rid of headlice? i know many people w/ headlice n they kept on asking me how 2 get rid of them. ok heres what works for head lice.  you put mayonaise all in your hair you leave it in your hair for 3 to 4 hours with a shower cap over it.  then you rinse the mayonaise out with vinegar.  then wash your hair and towel dry it.  then take the lice comb and go through your hair with it layer by layer.  continue to do this for about a week.  also wash all sheets, blankets, pillows etc that youve had your head on lately
