Which phase is transitional and degeneration?

Which phase is transitional and degeneration?

• A. Anagen
• B. Catagen
• C. Telogen
• D. Exogen

Answer: (B)

Catagen is the transitional phase in the hair cycle between active growth and resting. During this short stage, growth stops, the lower part of the follicle degenerates, and the hair bulb detaches from the dermal papilla, signaling the shift from growth to regression. This combination of ending growth and follicle degeneration is why it’s described as transitional and degenerative. In contrast, anagen is the active growth phase, telogen is the resting phase, and exogen refers to the shedding process, not the transitional degeneration inside the follicle.
