Telogen Effluvium, a condition characterized by hair loss, is commonly triggered by traumatic events such as serious illness, injury, surgery, stress, or physiological shock to the body. The human hair growth cycle consists of three stages: anagen, catagen, and telogen. During the anagen phase, hair actively grows, followed by the transitional catagen phase. Finally, the telogen phase is a resting period for the hair follicles. Telogen Effluvium occurs when a significant number of hair follicles suddenly enter the telogen phase, resulting in excessive hair shedding.
Is Telogen Effluvium Permanent?
Telogen effluvium is typically a temporary condition. However, for some individuals, it can become chronic, especially if the underlying disease or disorder responsible for it is chronic as well. In most cases, hair starts to regrow within three to six months after the triggering event has ended or been resolved. Occasionally, though, hair loss may be delayed and not commence until several months after the stressful incident. The average hair loss experienced by people with telogen effluvium is around 30 percent, although some individuals may lose up to half of their hair. Complete hair loss due to telogen effluvium is uncommon.
Signs of Telogen Effluvium
Identifying the presence of telogen effluvium can be done through several indicators. One common sign is the discovery of hair in the drain or an excess amount of hair caught in a brush after showering. Over time, individuals may also notice a decrease in hair volume or the widening of their hair parts, making their scalp more visible. If you suspect you have telogen effluvium, it is advisable to consult a medical professional who may conduct a wash test. During this test, the practitioner washes your hair and counts the number of strands lost in the process. Additionally, blood tests may be conducted to determine the underlying cause of hair loss. Another method used to differentiate telogen effluvium from other forms of hair loss is measuring the diameter and length of the hairs that are shed.
