hair

Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, sex, or religion.

The upper and lower lips are referred to as the "Labium superius oris" and "Labium inferius oris", respectively. The juncture where the lips meet the surrounding skin of the mouth area is the vermilion border, which is known for its prominent display in humans as well as a wide variety of mammals.[1] The vermilion zone of the upper lip is known as the cupid's bow. The skin of the lip, with three to five cellular layers, is very thin compared to typical face skin, which has up to 16 layers.[2] With light skin color, the lip skin contains fewer melanocytes (cells which produce melanin pigment). Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. With darker skin color this effec
