The telogen phase is the phase where the dead hair remains attached to the scalp (hair follicle). This phase lasts between 2 and 6 months, represents at all time approximately 15% of hair. In the telogen phase, the dead hair is gradually pushed from the hair root by a new hair follicle in the anagen phase, until it detaches and falls. It is therefore quite normal to regularly lose hair and to find them in small numbers on the hairbrush, the floor or the pillow. The hair life cycle, ending by this process of removing dead hair, repeats 25 to 30 times during a human life.
