Nanogen Hair Building Fiber, Medium Brown 30 Grams
Each individual keratin fiber is coated with a patent pending electrostatic coating. It is this coating that means Nanofibres dipolar charged. Dipolar charging is unique to Nanofibres, and means they bind perpendicularly to the hair, so every fiber thickens your natural hair as much as possible. Dipolar charged fibres are also better because they bind to hair even in high humidity or after some conditioners that change the charge of hair. The independent test report also shows only Nanofibres have significant perpendicular binding, for unique real hair density.
