Are all hairs on body the same structurally? explain. help please
yes they are all hairs on the body are the same because they are all made of growing proteins and in some people for example there hair may be course so the hair on there arms legs that sorta thing is going to grow in strong and dark so yes they r all the same structurally.
did this help at all?

No, all the hairs on our body are not the same structurally. There are two main types of hair on our body: vellus hair and terminal hair.
1. Vellus Hair: Vellus hair is short, fine, and often colorless or lightly pigmented. This type of hair covers most of our body, including areas like our arms, legs, and face. Vellus hair is relatively thin and has a shorter growth cycle, so it doesn't usually grow very long.
2. Terminal Hair: Terminal hair, on the other hand, is thicker, longer, and more pigmented than vellus hair. It is usually found in specific areas, such as the scalp, eyebrows, eyelashes, and pubic region. Terminal hair grows for a longer time before entering a resting phase, allowing it to grow much longer than vellus hair.
Furthermore, even within these two main types of hair, there can be variations in structure. For example, scalp hair tends to be thicker and stronger compared to the hair on our arms or legs. Additionally, different individuals may have variations in the shape, thickness, and texture of their hair based on genetic factors.
To understand the structural differences between hairs, you can observe them under a microscope or analyze hair samples using techniques such as scanning electron microscopy. These methods can provide detailed images of the hair shaft, cuticle, cortex, and medulla, which are the different layers that make up a hair strand.
