What signals the end of the growth phase?

1. Anlagen phase

2. Catagen phase

3. Telogen phase

4. Neogen phase

The correct answer is: Catagen phase

The catagen phase signals the end of the growth phase in the hair growth cycle. During the anlagen phase, the hair follicles are actively growing and producing new hair cells. The neogen phase is not a known phase in the hair growth cycle. The telogen phase, also known as the resting phase, occurs after the catagen phase and is when the hair stops growing and eventually falls out. So while the telogen phase is involved in the end of the growth phase, it is not the specific phase that marks its end. Therefore, B is the only correct option as it specifically refers to the growth phase.
