Keratin is a naturally occurring protein in the human body that makes up physical structures such as hair and nails. When these basic structures are weakened and keratin is lost, keratin can be added through the cosmetic process to fill in the voids of the original keratin fibers, providing better strength. Most commonly, people use keratin as a hair straightening treatment. Possible keratin side effects include hair loss, allergic reactions, itching, rash, eye irritation, lungs, throat, mouth and nose, dry hair, and cancer. These side effects do not come from keratin itself, but from processing tools and additives contained in keratin products that help them work.
