Hair Root Sheath (Not a bug)

Natural Habitat

Found on the scalp or skin of mammals, often seen when a hair is plucked or shed during the telogen phase.

Diet & Feeding

Not an organism; does not eat. It is biological tissue nourished by blood supply in the skin.

Behavior Patterns

This is stationary biological tissue. The white bulb indicates the hair was likely in the telogen (resting) phase or plucked with the inner root sheath intact. It is not parasitic or alive independently.

Risks & Benefits

No risks; this is a normal part of human anatomy. It is frequently mistaken for lice nits or parasitic worms due to its whitish, bulbous appearance.
