#During telogen, or the resting stage, the hair stops growing and is retained in the hair follicle as a dead hair. A telogen hair is characterized as a small hair, approximately one-third the length of the anagen hair. Hairs continue to grow until they reach a preset length and then enter the resting phase. The hair will remain in this state until a new hair starts to grow, pushes the old hair out, and the old hair is shed. <br><br>
