Q1. What is a common cause of hair loss related to stress?
- A. Improved blood circulation
- B. Telogen effluvium ✓
- C. Increased hair growth
- D. Stronger hair follicles
Why: Stress can push a large number of hair follicles into the telogen (resting) phase, leading to telogen effluvium, which is a common type of stress-related hair loss.
Q2. Which of the following hormones is released during stress and may contribute to hair loss?
- A. Insulin
- B. Cortisol ✓
- C. Estrogen
