"Silicon K New Life" is a great product for prolonging the life of your hair system.  It keeps the hair from tangling up because each time you use the product, it applies a thin coat of silicon onto the hair and that keep the hair from also looking old and gives a healthy look even to old hair systems.This product out performs all the other spray and tonics, conditioners, etc. There are plenty of products out there that restore and I even sell a handful myself, but this product works best to maintain all areas. It shows results once you spray it onto your hair system.
