In the context of hair growth, which phase is known as the resting phase?

The phase known as the resting phase in the context of hair growth is Telogen. During this phase, hair follicles are in a state of inactivity. Hair that is in the telogen phase is not growing and is simply resting before it eventually sheds and is replaced by new hair in the subsequent growth cycles. The telogen phase usually lasts for several weeks to a few months, depending on various factors such as the individual's hair growth cycle, health, and genetics.

Understanding the hair growth cycle helps in comprehending how hair may shed or appear less voluminous during the telogen phase. In contrast, the anagen phase is the active growth phase, where hair is consistently growing, and the catagen phase is a transitional phase where growth stops and the hair follicle shrinks. The exogen phase, while sometimes considered a part of the telogen phase, refers specifically to the process of shedding, which occurs after the telogen phase has ended.
