Telogen effluvium is characterised by abundant and diffuse reactive hair loss, affecting the entire scalp. Generally temporary, it lasts between two and four months and can be triggered by various traumatic events such as intense stress, miscarriage, stopping hormonal contraception, surgery, severe infectious diseases, emotional shocks, or a strict diet causing deficiencies.
Hair loss often occurs two to four months after the triggering event. In women, telogen effluvium results in a noticeable thinning of the hair, sometimes with the loss of entire clumps, making the experience particularly distressing.
Telogen effluvium is usually temporary. Hair regrowth occurs naturally after the fall phase, and the hair gradually regains its normal density.
