Why is the bottle of Kmax keratin fibers not filled completely?
The bottles are never filled to the brim, but the amount of fibers contained within them is always slightly higher than that shown in the package, because the packaging machinery is calibrated to a greater quantity than expected. The bottle is not filled completely because there is the empty space necessary to vigorously shake the product producing the electrostatic charge necessary for the fibers to attach themselves to natural hair.
