In a normal healthy person's scalp about 85% of the hair follicles are actively growing hair and 15% are resting hair. A hair follicle usually grows anagen hair for 4 years or so, then rests for about 4 months. The resting or telogen hair has a club or bulb at the tip. A new anagen hair begins to grow under the resting telogen hair and pushes it out. For more information visit the telogen effluvium treatments.
