What about the hairpiece they showed on Beyond 2000? It looked very realistic and was completely undetectable unless you can detect the so called mesh which is 30 micons thin i.e. 1/3 the thickness of paper and very strong. The only drawback is that is has to be redone every 2 weeks but then it's always new and wont wear out like other peices. Also it's more expensive. The company is Propia and it's from Japan.
