THE HUMAN HAIR
As an individual, you need to take good care of yourself. This involves personal hygiene and good grooming. These are necessary for good health and personal appearance .Your appearance is also very important. This is because it is your appearance that tells people about the kind of person you are.
Personal hygiene and good grooming requires cleanliness of every part of the body including Hair, Eyes, Ears, Teeth, Skin and Legs.
All mammals have hair, a slender, threadlike outgrowth of the epidermis. Each strand of hair is composed of a scleroprotein called keratin and lacks both blood vessels and nerves. Both the color and form of human hair and the shape of the hair follicle serve as reliable determinants of racial and ethnic heredity.
The hair is defined as a slender, threadlike outgrowth of the epidermis. Your hair is one of your greatest assets. Healthy and well groomed hair helps to improve your personal appearance. The condition of your hair depends on factors such as food, heredity and proper care,
Each hair grows from a narrow tube in the skin called the hair follicle. Hair follicle has a tiny oil gland near its base. The gland produces oil that lubricates the hair and softens the skin around it.
A hair grows upward from the root. Lengthening fibres of keratin-filled dead cells, grouped around the semi hollow medulla, make up the cortex. A living structure called the bulb (visible as a white lump at the end of a plucked hair) surrounds and feeds the root, which lies in a pocket of the epidermis called the follicle. Hair grows fastest when it is short.
