karvatyypeillä

Karvatyypeillä refers to the different kinds of hair found on the human body. These can be broadly categorized into vellus hair and terminal hair. Vellus hair, often called peach fuzz, is fine, short, and lightly pigmented, typically covering most of the body in children and adult women. Terminal hair, on the other hand, is longer, thicker, and darker. It grows on areas like the scalp, eyebrows, eyelashes, and in males, on the face, chest, and limbs, especially after puberty.

The growth and characteristics of hair are influenced by genetics, hormones, and age. Hormonal changes, particularly the increase of androgens like testosterone, play a significant role in the development of terminal hair during puberty. The distribution of these hair types varies greatly between individuals and is a key aspect of human physical variation. Factors like ethnicity can also contribute to differences in hair texture, color, and density. Understanding these variations helps in fields ranging from dermatology to anthropology.
