The hair growth stage when all cell division stops is referred to as the?

The correct answer identifies the catagen stage as the period in hair growth when all cell division ceases. This transitional phase follows the anagen stage, where the hair actively grows, and leads into the telogen stage, which is the resting phase.

During the catagen stage, the hair follicle shrinks and detaches from the dermal papilla, meaning that the cells that produce hair are no longer dividing or generating new hair fibers. This is a critical phase because it signals the completion of the hair’s growth cycle before the hair finally falls out during the telogen stage. Understanding the dynamics of these stages is essential in hair removal practices, as they dictate the effectiveness of various removal techniques based on whether the hair is actively growing, transitioning, or resting.
