Telogen effluvium is a temporary hair loss condition characterized by increased shedding of hair due to a stressor or a change in hormonal balance. It’s often noticed as an increased amount of hair in the hairbrush, shower drain, or on pillows, and can be triggered by events like childbirth, illness, surgery, or even emotional stress.
Key aspects of telogen effluvium:
Trigger: A stressor or hormonal change can cause a large number of hair follicles to prematurely enter the resting (telogen) phase.
Timing: Shedding typically begins a few months (2-3 months) after the trigger.
Appearance: Hair may appear thinner, and more hair than usual may be lost.
Duration: It’s generally a temporary condition, and hair regrowth usually occurs within several months, often within 6 months, according to the British Association of Dermatologists.
Treatment: No specific treatment is usually needed, as hair growth will resume once the underlying cause is resolved.
Causes and triggers:
Stress:
Physical or emotional stress, like illness, surgery, childbirth, or even major life changes.
Hormonal changes:
Postpartum hormonal changes, particularly a drop in estrogen, can trigger telogen effluvium.
Medications:
Certain medications, like beta-blockers, retinoids, and anticoagulants, can also be a cause.
Nutritional deficiencies:
Iron deficiency or other nutrient deficiencies can contribute.
Underlying medical conditions:
Hypothyroidism (underactive thyroid) and other medical conditions can also be linked.
Symptoms:
Increased shedding of hair, Thinning hair on the scalp, and Hair that is easily plucked out.
Diagnosis:
Telogen effluvium is typically diagnosed based on clinical features, such as diffuse hair thinning and increased shedding, according to DermNet.
Note: While most cases resolve spontaneously, if hair loss is severe, persistent, or you have concerns about the cause, consulting a doctor or dermatologist is recommended.
