Telogen effluvium is a scalp disorder characterized by the thinning or shedding of hair resulting from the early entry of hair in the telogen phase (the resting phase of the hair follicle).[1][2]

Emotional or physiological stress may result in an alteration of the normal hair cycle and cause the disorder.

Telogen effluvium may be caused by eating disorders, fever, childbirth, chronic illness, major surgery, anemia, severe emotional disorders, crash diets, hypothyroidism, and drugs.[1][3]

Diagnostic tests, which may be performed to verify the diagnosis, include a trichogram, trichoscopy[4] and biopsy.[3]

Vitamin D levels may also play a role in normal hair cycle. [5]
