What characterizes the telogen phase of hair growth?

The telogen phase is a crucial stage in the hair growth cycle that is characterized primarily by the hair being in a resting state. During this phase, which typically lasts several weeks to a few months, hair follicles do not actively produce new hair. Instead, the existing hair remains in place while the hair follicle prepares for the next growth cycle. This stage is significant because it allows the hair to remain attached to the scalp, even though it is not growing or undergoing any active changes.

At the end of this phase, it's common for the hair to eventually enter a shedding process, transitioning to a new phase known as shedding or exogen. However, during the telogen phase itself, the hair is stable and not experiencing growth or significant breakdown, distinguishing it from other phases of the hair growth cycle.
