Which stage occurs last in the hair growth cycle?

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

Answer: (B)

Hair growth happens in three main phases: a long active growth phase, a short transition phase, and a resting phase. The resting phase is the final stage in this sequence because the follicle is dormant and the old hair remains in place until it is shed, making way for the next growth cycle to begin. The duration of the resting phase allows time for the hair to shed gradually and for new growth to eventually start. Some sources describe shedding as a separate exogen phase that can follow telogen, but for this exam’s framework the resting phase is considered the last step before regeneration.
