There are various kinds of wraps that are used in spa centres and beauty salons. Some use seaweed, others dead sea salt, de-toxifying herbals etc. They do work, but some people don't like the fact that they are wrapped fairly tightly and you can't move much while they are on. I've had it a few times and felt great afterwards - and yes, I did lose inches! Don't try doing it at home, as it is really not possible to do a good job with the wrapping yourself, even though some companies do sell home kits. These companies are just out for your money, not for quality. Go to a good salon or spa centre and you will be fine. Best thing is to just sleep while wrapped up. You will wake up refreshed and feeling great and that little bit slimmer! Unless you do them regularly though, it may just be temporary inch loss. Good luck!
