Which phase of the hair growth cycle is known as the resting phase?

The resting phase of the hair growth cycle is known as telogen. During this phase, hair growth ceases, and the hair follicle is not actively growing or shedding hair. It is a period of dormancy that can last for several weeks to months. By understanding this phase, it's important to note that after telogen, the hair can eventually be shed and a new hair will start its growth cycle again.

In the context of the phases of hair growth, catagen refers to a transitional period where hair stops growing and the follicle begins to shrink, while anagen is the active growth phase where the hair is continuously produced. Exogen represents the phase when the hair is being shed and may happen alongside telogen, but it is not specifically recognized as the resting phase. Thus, telogen is distinctly identified as the resting phase in the hair growth cycle.
