Answer 1

Answer:

When you’re a baby, you have lanugo hair.

This soon changes to vellus hair in childhood, which helps the body regulate its temperature.

It’s often referred to as “peach fuzz” or “baby hair” because of its appearance, which is short, thin (less than 1/13th of an inch longTrusted Source), and lightly colored. Common areas include the nose, ears, and even eyelids.

Once puberty hits, however, the body hair transforms again. Vellus hairs become terminal, meaning that they become thick, strong, and darker in color.
