Definition: The telogen phase is the resting phase of the hair follicle. At any given time, 10%-15% of all hairs are in the telogen phase. This phase lasts for about 100 days for hairs on the scalp and much longer for hairs on the eyebrow, eyelash, arm and leg.

During this phase the hair follicle is completely at rest and the club hairis completely formed. Pulling out a hair in this phase will reveal a solid, hard, dry, white material at the root.

About 25-100 telogen hairs are shed normally each day.
