Can Air Pollution Really Cause Hairfall? Evidence Remains Limited

Most people lose hair for reasons such as family traits, hormones, stress or nutrition.

Air pollution might also affect hair, but scientists do not yet know for sure that it causes hair loss.

Many studies have looked at cells or animals rather than people.

Studies of populations have found a connection, but that does not prove pollution is the cause.

The possibility may matter more in cities with heavy smog.

Washing your hair after days with lots of pollution may help remove pollutants.

Covering your hair outside when the air is poor is another simple step.

Eating foods rich in antioxidants is also suggested.

If hair loss starts suddenly or happens in patches, see a dermatologist.
