Hair is present on all parts of the body except the palms, soles and the red portion of the lips. The pattern of hair distribution, its density and longevity depend on a person's hereditary influences, nutrition and medical status. Soft, long hair occur on the scalp, beard, axilae and pubis. Stiff hair or bristles are found in eyelashes, eyebrows and inside the nose. On the rest of the body, downy unpigmented hair is found.
Nails are convex, translucent horny plates situated at the tips of our fingers and toes.
The outer exposed part of the nail is called the nail plate and the hidden part lying underneath the skin cuticle is the nail root which grows forward to form a nail plate. It is a common observation that some people have rough dry skins, while others have smooth shiny skins. This is because of the variations in the secretion of sebaceous glands which secrete an oily substance giving texture to the skin. Many people have a bad odour in their perspiration and at times, they find themselves in very embarrassing situations. The sweat reacts with the bacteria on the skin and causes this odour.
