TLDR Telogen effluvium is hair loss caused by many hairs stopping growth suddenly, often due to stress or illness, but sometimes it's normal and not due to disease.
The document from 21 years ago discussed Telogen effluvium, a condition where a large number of anagen hairs from all areas of the scalp prematurely enter the telogen phase. This can be triggered by various internal stressors to the follicles, such as metabolic disturbances, nutritional deficiencies, or serious systemic illnesses. However, some cases are 'physiological,' and do not indicate disease. Once the hairs enter the catagen phase, they must go through the telogen phase and shedding before a new anagen hair can regrow.
