Why does telogen effluvium cause hair loss?

Each scalp hair moves through growth, transition, resting and shedding phases. Telogen effluvium happens when a trigger shifts more follicles into the resting phase around the same period. The hairs do not all fall immediately; shedding becomes noticeable when those resting hairs release from the scalp later.

Possible triggers include a significant illness, emotional or physical stress, childbirth, restrictive eating, some medicines or a major change in the body. The timing can make the original trigger easy to overlook. Hair Loss is a very common presentation of Telogen Effluvium, although other scalp conditions can also cause shedding and need different care.

Make a note of when shedding began and what happened beforehand, including illness, diet changes, new medicines and hormonal events. Handle hair gently, avoid tight hairstyles and harsh chemical treatments, and eat regular balanced meals. A clinician may examine the scalp and consider blood tests when symptoms suggest a nutritional, thyroid or other medical contributor. Treatment focuses on the trigger when one is found.

Arrange a review if shedding is sudden and severe, continues, forms smooth patches, affects the eyebrows, or comes with scalp pain, scale, redness or scarring. Seek prompt care for hair loss with marked weakness, unexplained weight change or other new body symptoms. Early examination can separate diffuse shedding from inflammatory or patchy disorders.

Ask which recent events could have shifted the hair cycle; whether the pattern fits diffuse shedding; whether medicines, nutrition or thyroid function need review; and how progress will be monitored as the scalp returns to its usual cycle.
