Collagen is an important protein of the body's connective tissue. Keratin is a tough protein that hair and nails are made of. Both are important in hair's structure and health. As a person ages, the body loses the ability to make collagen. Hair can become dry, brittle, coarse, break easily and fall out. Keratin is the dominant protein for keeping hair strong. Collagen can improve hair's appearance and follicles. Hair care products containing collagen do not just work on the outside layers of the hair, they work all the way down to the scalp and the hair cuticles.
