The Fermodyl formulations use these protein molecules to penetrate right to the cortex of the hair shaft and then build from within. This chemistry is unique within the hair care industry.

Standard hair products may improve hair strength by less than 1%. But by interacting with the hairs make up, the Fermodyl formulations improve the tensile strength of damaged hair by up to 15% and increase the diameter of the hair shaft by up to 20%. By increasing tensile strength, Fermodyl Interactives help weaker hair become stronger and help prevent breakage.
