Did you mean Type I Keratin?

Glossary Type I Keratin

Type I keratin is a fibrous protein that is a key structural component of hair, skin, and nails. It is classified as an acidic keratin and is primarily found in the hard tissues of the body, contributing to the strength and resilience of hair strands. In the context of hair loss, understanding type I keratin is relevant as it plays a crucial role in hair follicle health and integrity; any disruption in its production or structure can lead to weakened hair and increased susceptibility to hair loss. Distinguishing characteristics of type I keratin include its high tensile strength and its ability to form complex structures with other keratins, particularly type II keratins, to create the overall architecture of hair.
