Why don't you bleed when you pull a hair out?

When you pull out a hair, you typically don't bleed because hair follicles are not surrounded by blood vessels; they are located in the dermis layer of the skin, which contains the blood supply. The hair itself is made of keratin and is not living tissue, so removing it usually doesn't affect the surrounding skin or cause damage to blood vessels. However, if the hair is pulled out forcefully or if the skin is irritated, it may cause minor bleeding or soreness.
