Vellus hair is the fine, colorless or light-colored hair that covers most of our body. It is different from terminal hair, which is thicker and darker in color. Vellus hair is most commonly found on areas such as the face, arms, back, and chest.
Unlike terminal hair, vellus hair is very soft and almost invisible. Its purpose is to regulate body temperature and provide a protective layer for the skin. While vellus hair is present on most parts of the body, it is more noticeable in certain areas, such as the face in females.
Development of Vellus Hair
Vellus hair is present on our bodies from birth, but it becomes more prominent during puberty. During this time, hormonal changes cause some vellus hair to transform into terminal hair, particularly in areas like the armpits and genital region. This transformation is what leads to the development of pubic hair and axillary hair.
Vellus Hair Growth Cycle
Similar to terminal hair, vellus hair goes through a growth cycle that includes anagen (growth phase), catagen (transitional phase), and telogen (resting phase). However, vellus hair has a shorter anagen phase compared to terminal hair, which is why it remains short and fine.
Role of Vellus Hair
Although vellus hair is very fine and almost invisible, it plays a crucial role in protecting and insulating the skin. It helps in regulating body temperature by trapping heat close to the body. Additionally, vellus hair provides a barrier against external elements, such as dust and pathogens.
In conclusion, while vellus hair may seem insignificant, it serves important functions for our bodies. Understanding the differences between vellus and terminal hair can help us appreciate the complexity of our hair growth patterns and the role each type of hair plays in our overall well-being.
