- ATelogen phase
- BAnagen phase

Show answer & explanationAnswer & explanation
Correct answer: B. Anagen phase
Anagen is the active growth phase where the hair matrix actively divides and produces new hair, lasting anywhere from 2 to 6 years. Catagen is a short transitional phase, and telogen is the resting phase before shedding.
Why the other options are wrong
- A. Telogen is the resting phase where growth has stopped.
- C. Catagen is the brief transitional phase, not active growth.
- D. Exogen refers to shedding, not active growth.
Anagen Phase
The active growth phase of the hair cycle during which the hair follicle produces new hair cells.
- Lasts 2-6 years on average
- About 90% of scalp hair is in this phase at any time
- Followed by catagen and then telogen
