Instantly Ageless® Hair in Seconds™ is actually the second generation of hair building fibers. Our new technology sets us apart from our competitors. The difference is subtle and almost impossible to discern with the naked eye, but under magnification of 100x, the slimmer and longer fibers make all of the difference. In our new formulation, the fibers are all the same length which makes a much more natural look. They are also very difficult to distinguish from a natural human hair and will not block pores.
