This  is great, because it works in those places where it's sometimes
difficult to get to with tweezers: between toes, in the middle of a  head full of dark  hair,  etc. 

Apply a glob of liquid soap to a cotton ball. Cover the tick with  the
soap-soaked cotton ball and let it stay on the  repulsive insect for a few seconds (15-20), after which the tick  will come out on it's own and be stuck to the cotton ball  when  you lift it away. This technique has worked every time I've  used it (and that was frequently), and it's much less traumatic  for the patient and easier for me. 

Unless  someone is allergic to soap, I can't see that this would be
damaging  in any way. I even had my doctor's wife call me for advice
because  she had one stuck to her back and she couldn't reach it with 
tweezers. She used this method and immediately called me back to say, "It  worked!" 
 
Please pass on;  everyone needs this helpful hint.
