Arm hair

Arm hair is hair that grows on a human's forearms. Sometimes this covers even the elbow area.

This is typically thought as a male trait as men have terminal hair on their arms, making them noticeable, particularly if they have black hair. Terminal arm hair is concentrated on the wrist end of the forearm, extending over the hand.

Terminal hair growth on arms is a secondary sexual characteristic in boys and appear in the last stages of puberty. If boys have arm hair before this stage, it is long, heavy vellus hair, and this is rare. Vellus arm hair is usually concentrated on the elbow end of the forearm and often ends on the lower part of the upper arm.

This type of vellus hair growth on arms sometimes occurs in young women and girls.
