Medicines for Telogen effluvium

What it is

Telogen effluvium is a common cause of temporary, diffuse hair shedding, in which more hairs than usual enter the "resting and shedding" phase of the hair cycle and then fall out together. It typically becomes noticeable a couple of months (often around three) after a trigger that has stressed the body, and causes a general thinning all over the scalp and noticeably more hairs coming out when washing or brushing, rather than distinct bald patches. Common triggers include a significant illness (including a high fever or infection), childbirth (very common), major surgery, severe stress, a crash diet or significant weight loss, iron deficiency, thyroid problems, and starting or stopping certain medicines. The reassuring key feature is that it is usually temporary: once the trigger has passed and any underlying factor is addressed, the hair cycle recovers and the hair grows back over several months. It does not cause permanent baldness.

How it is treated

The main approach is reassurance and addressing any underlying trigger, as telogen effluvium usually resolves on its own once the cause has passed. Understanding that the increased shedding is a delayed response to an earlier trigger — and that the hair will regrow — is helpful and reduces worry (which is important, as anxiety about the shedding does not help). Where there is a treatable contributing factor, such as iron deficiency or a thyroid problem, checking for and correcting it supports recovery, so a doctor may do some blood tests. Good general health and nutrition, and gentle hair care, help. No specific treatment is usually needed, and recovery of hair density generally occurs over several months, though it can take a while. If shedding is very prolonged, or there are other features (such as patchy loss or scalp problems), further assessment is arranged. The reassuring message is that telogen effluvium is a temporary, recoverable form of hair shedding, not permanent hair loss.
