ICD-11 definition : Acute telogen effluvium is an acute-onset scalp hair loss that occurs two to three
months after a triggering, often life-threatening, stress which interrupts normal
anagen hair growth. It is commonly seen in survivors who have required intensive care
for severe sepsis, blood loss, inflammatory disease or trauma. It may also result
from acute starvation. Large numbers of anagen hairs are converted to telogen and
are shed two to three months later resulting in a diffuse alopecia.;
