Final answer:
The most common type of stress-induced hair loss is Telogen Ef`f`lu`vium.
Step-by-step explanation:
This condition occurs when there is a disruption in the normal hair growth cycle, leading to excessive shedding of hair. Stress can push a large number of hairs into the telogen (resting) phase prematurely, causing them to fall out.
During periods of high stress, the body releases stress hormones such as cortisol, which can affect the hair follicles. This can result in a higher percentage of hairs entering the telogen phase and eventually shedding.
It's important to note that Telogen Ef`flu`vium is usually a temporary condition and the hair typically regrows once the underlying stress is resolved.
