Telogen Effluvium

Telogen effluvium (pronounced: təˈlɒdʒən ɪˈflʊviəm) is a common type of hair loss that occurs when a significant number of hair follicles on the scalp enter the resting (telogen) phase of the hair growth cycle simultaneously, causing the affected hairs to fall out.

Etymology

The term "telogen effluvium" is derived from the Greek words "telos" meaning "end", and "effluvium" meaning "outflow", referring to the end phase of the hair growth cycle and the outflow of hairs from the scalp.

Causes

Telogen effluvium can be triggered by various factors, including severe stress, major surgery, significant weight loss, chronic illness, or a high fever. Certain medications, such as beta blockers or antidepressants, can also cause telogen effluvium.

Symptoms

The primary symptom of telogen effluvium is an increase in hair shedding. The hair loss is usually diffuse and often more severe in certain areas of the scalp. The hairs that fall out are typically telogen hairs, which can be identified by a small bulb of keratin on the root end.

Treatment

Treatment for telogen effluvium primarily involves addressing the underlying cause of the hair loss. This may involve discontinuing a medication, managing stress, or treating an underlying medical condition. In some cases, minoxidil (Rogaine) may be recommended to help stimulate hair growth.
