Does anesthesia cause hair loss?

Anesthesia does not cause hair loss, according to NetWellness. Hair loss that occurs after surgery or general anesthesia may be caused by the stress of the surgery and recovery process.

There are two types of alopecia, a condition that causes hair loss. Pressure alopecia causes hair loss when a specific area of the scalp is subject to prolonged pressure. This type may occur during a long surgery or immobile recovery process. In this condition, hair loss only occurs in the area that was under pressure. Telogen effluvium alopecia may occur during acute stress, such as stress endured under major surgery or illness, and results in general hair loss, as stated NetWellness.
