process where hair follicle cells produce and harden keratin
Follicular keratinization is the process by which cells in the hair follicle produce keratin, a protein that forms the structure of hair. This process involves the hardening and flattening of these cells as they move up the follicle, eventually forming the hair shaft. Proper keratinization is essential for healthy hair growth, while abnormalities in this process can lead to hair disorders.
