Some wraps are good, some are crap, a lot just take water, so as soon as you have a glass or two of water you just but it back. Some can be good for detoxing the skin. Iwent and had professional universal contour wraps before, and they measure you before and after, and guarantee several inches of weight loss and if you gain it back within a week you get your money refunded, they were very affective, and great foor lymph drainage (like colonic for the skin!)
