Full Answer

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.

Dermatologists look at the roots of hair to determine if it is falling out due to telogen effluvium, reports WebMD. If the hair has a club-shaped bulb at the end, this indicates it has gone through an entire growth season that was abnormally accelerated by the stressful event.

When hair loss is at its peak due to telogen effluvium, hair may fall out by the handful, says WebMD. While this is alarming, the hair loss is usually temporary and resolves with time. Hair usually begins to grow back six months after the event that caused the telogen effluvium. A diet with sufficient iron and protein helps the hair grow back.
