Epithelial keratins are a group of fibrous proteins that form a key component of the cytoskeleton in epithelial cells, including those in the hair follicle. They play a crucial role in maintaining the structural integrity and resilience of hair and skin. In the context of hair loss, abnormalities or mutations in keratin genes can lead to conditions such as alopecia or other hair disorders, highlighting their importance in hair biology and health. Key distinguishing characteristics include their ability to form intermediate filaments, which provide mechanical support and protection to cells.
