04. What’s the difference between the 1st generation and the 2nd generation FULLY Hair Building Fibers?

     There’re 3 differences:

1. The 2nd generation is made slimmer, longer, softer and lighter than the 1st generation. It can match naturally to the real human hair. It will not make people feel dusty on the head after apply.

2.  The 2nd generation is made of 100% natural ingredients, it’s bactericide-free and preservative-free, it will not cause any skin or health problem even keep using for years to come.

3. The each single of 2nd generation FULLY hair building fibers carries the homopolar negative ion.
So the hair fiber will not have the chance to clump together inside nor outside the bottle.
And the dispersibility and Static adsorption ability are greatly developed than the 1st generation.
