Can your hair fall out after an operation?

Yes, hair loss, known as telogen effluvium, can occur after an operation. This type of hair loss is temporary and typically happens when the body is under significant physical or emotional stress, such as that experienced during or after an operation. Here's how it occurs:

1. Stress Reacts:

An surgery can cause the body's "fight or flight" response to be activated, leading to the release of stress hormones like cortisol. These hormones can disrupt the hair growth cycle.

2. Hair Growth Cycle Interrupted:

The hair growth cycle consists of three phases: Anagen (active growth), Catagen (transitional), and Telogen (resting).

Stress can force a large number of hairs into the Telogen phase prematurely,causing them to remain dormant.

3. Hair Loss:

After a few months, the Telogen hairs are shed when new Anagen hairs begin to emerge. This can lead to noticeable hair thinning or loss, usually starting about 2-3 months after the operation.

4. Temporary Condition:

Telogen effluvium is usually temporary and resolves on its own within 6-9 months.

However, if the hair loss persists or is severe, it's essential to consult a dermatologist or healthcare provider to rule out any other potential causes and receive proper treatment.
