Cleansing is a detoxification technique that many models and celebs use throughout their careers. Regular cleansing, they claim, is not only great for losing weight but it also clears complexions and strengthens hair and nails. The most popular cleanse is the colon cleanse, but there are also liver and kidney cleanses. The first stage in a colon cleanse is to stop any more toxins from entering the system by eating only fresh organically grown vegetables. The second stage adds cleansing supplements such as Bentonite and Psyllium. Bentonite absorbs the toxins, while Psyllium pushes them through and out of your system. Supposedly Ben Affleck, Courtney Love, Andie Macdowell, Janet Jackson, Cindy Crawford, Alicia Silverstone, and Liv Tyler are all regular cleansers, and many other celebs have gotten into the habit of cleansing before big awards shows.
