Vellus Hair: What Is It and How Does It Grow?

Vellus hair is the short, soft hair that covers most of the human body. You might not even know you have it, but this type of hair plays an important role in keeping your skin healthy. In this blog post, we'll take a closer look at vellus hair, how it grows, and what its purpose is.

What Is Vellus Hair?

Vellus hair is the type of hair that covers most of the human body. It's usually short, soft, and barely noticeable. In fact, you might not even know you have it! This type of hair is different from the terminal hairs that are found on the head, eyebrows, and eyelashes. Terminal hairs are longer, thicker, and darker than vellus hairs.

How Does Vellus Hair Grow?

Vellus hair grows from tiny follicles in the skin. These follicles are much smaller than those that produce terminal hairs. Each follicle contains a tiny muscle called an arrector pili. This muscle is responsible for making the hair stand up when it's cold or when you're scared.

What Is the Purpose of Vellus Hair?

Vellus hairs serve several important functions. First, they help to keep the skin warm by trapping heat close to the body. They also help to protect against UV rays and other environmental hazards. Finally, vellus hairs can help to regulate oil production and keep the skin healthy.

Conclusion

Vellus hairs play an important role in keeping our skin healthy and protected from environmental hazards. Although they're usually short and soft, these tiny hairs serve a big purpose! Next time you're feeling down about that pesky peach fuzz on your face, remember that vellus hair is there for a reason.
