During which phase does the hair signal the end of its active growth?

1. Anagen

2. Catagen

3. Resting

4. Telogen

The correct answer is: Anagen

During the anagen phase, the hair is actively growing and receiving nourishment from the blood supply. This phase can last anywhere from 2-7 years, depending on the individual. In contrast, during the catagen phase, the hair stops growing and the follicle begins to shrink. The resting phase, also known as the telogen phase, is when the hair is no longer connected to the blood supply and is preparing to shed. So, during the Telogen phase is when the hair signals the end of its active growth, as it is no longer receiving nourishment and will eventually fall out.
