Which stage reflects the period when the papilla starts to separate from the matrix of the hair bulb?

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

Answer: (D)

The period when the papilla begins to separate from the hair matrix occurs during catagen, the transitional stage between active growth and rest. In catagen the lower part of the follicle regresses, the hair bulb shrinks, and the dermal papilla pulls away from the matrix, effectively stopping hair production and preparing the follicle for the resting phase. During the active growth phase, the papilla stays attached to the matrix to support continuous production. In the resting phase, the follicle is dormant and sets up for re-entry into growth, while exogen refers to the shedding of the hair shaft after resting.
