Keyfibre Bonder Mask 300ml from Emsibeth Cosmetics is a professional restoring hair mask for salon use. It restores, regenerates and restructures the hair fibre, and it returns strength, elasticity, softness and shine to hair where keratin is missing or depleted. The formula is built on Rice Peptides and Amino Acids. Because they have a low molecular weight, they get into the hair shaft and gather where keratin is missing or depleted. Processing takes 3 to 5 minutes on damp hair, so it fits easily into a basin service.
