Final answer:
The Catagen Stage of hair growth is a brief, transitional phase lasting about 2 to 3 weeks, marking the end of active hair growth and the beginning of the shedding process.
Step-by-step explanation:
The Catagen Stage of hair growth is a transitional phase that follows the active growth period known as the anagen phase. This stage is characterized by a cessation of hair follicle cell division and lasts approximately 2 to 3 weeks. During this time, the hair follicle shrinks and detaches from the dermal papilla, setting the stage for the hair to eventually be shed during the next phase, the telogen phase, where the hair is at rest.
