BC Fibre Force is a new dimension of hair repair returning even most eroded hair to its optimal level of force & resilience. For the first time the formulas with Micronized Hair-Identical Keratins penetrate deeply into the hair architecture to re-cement specifically the Cell-Membrane-Complex, the intercellular bonding cement responsible for strong & resilient hair fibre. To use: Work into towel-dried hair & rinse out after 2 minutes. Please note this salon size product does not come with a pump.
