Do you know what to do with eyelashes?

if any eyelash comes out,  place it between  thumb and forefinger.  If you chose correctly which digit it stuck  to, you got a wish.

Should an eyelash fall out you pick it up with one finger, close your eyes and make a wish and then blow hard....  should the eyelash not be blown away then the wish won't come true.

Put the lash on the back of your hand and try to blow it off - make a wish, and then blow hard and if the lash blows away, the wish will come true.

An eyelash should be put in the palm of the hand - make a wish, and then blow  hard and if the lash blows away, the wish will come true.
 
Hair and nail clippings should  be burned so witches can't get them and cast a  spell on you.
