First, a hair follicle contains epithelial cells — a cell type that lines the body's vessels and cavities — as well as a specific kind of adult stem cell called dermal papillae.

Almost 100 research teams around the world have now used these special mice to help find adult stem cells in hair follicles, liver, muscle, and other tissues.

Given this, it shouldn't come as a surprise that if these stem cells are destroyed, so is the hair follicle (Ohyama et al., 2006; Ohyama 2007).
