The Pro Longer range is suitable for long, fine hair. Thanks to amino acids and the exclusive FILLER A-100 complex, the hair fiber is densified from root to tip. In addition, the hair is strengthened, shiny and protected from future damage.

In a Pro Longer ampoule there is an ultra-concentrated formula which penetrates the hair fiber to densify from the inside then smooth the surface. Hair is instantly thicker, stronger and shiny.
