I initially heard about this on the local morning news broadcast.
I think the key is to be present when it is being done to someone else before you invest your money, if you do at all. It is a custom hair weave so they have to measure your head before they order the hair. They sell the methodology to stylists who can be come distributors of the hair & learn the hair application technique, which is supposed to stay on the head but not have to be sewn in or glued in. When I wore my weave it was a sewn in type and so I can't imagine how the Jonetics hair is applied without being sewn in, at least a little.
