What type of hair is generally not influenced by hormones and remains fine and soft?

The type of hair that is generally not influenced by hormones and remains fine and soft is vellus hair. Vellus hair is the short, thin, and slightly pigmented hair that covers most of the human body, especially in areas such as the cheeks, forehead, and arms. This hair type is typically less dense than terminal hair and does not undergo the same hormonal influences, which can cause terminal hair to become thicker and coarser during puberty and in response to certain hormonal changes.

Vellus hair is often referred to as "peach fuzz" and is primarily found in pre-pubertal individuals. It is soft because it is not affected by hormones that contribute to the development of coarser hair types. Understanding the characteristics and development of vellus hair is crucial for practitioners in fields such as electrolysis and laser hair removal, as it helps in determining the appropriate treatment methods for different hair types.
