1. THE SKIN HAIR, SCALP & CONSULTATION

2. THE SKIN EPIDERMIS DERMIS HYPODERMIS

3. The epidermis This is the skin we see and touch on our bodies; it has several LAYERS constantly growing from the bottom layer moving towards the top layer. The epidermis contains no BLOOD vessels and very few nerves. The surface of the hair and skin is coated in a protective layer of secretions from the SEBACIOUS gland and the SWEAT gland. This coating has a pH of 4.5 - 6, which is acidic and is therefore referred to as the ACID MANTLE. Fill in the gaps using the words listed in the box below. Words: SWEAT LAYERS MANTLE SEBACIOUS BLOOD ACID 4.5 - 6

4. The Dermis Like the cortex of the hair, this is where it all happens. The dermal layer is between 1 and 4 mm in thickness and contains the root of the hair, nerves, blood vessels, muscles and glands. The sebaceous gland Produces a lubricant to the hair and scalp called SEBUM. It helps keep the skin supple and the hair shiny. If this gland produces too much sebum, it will cause the hair to become GREASY. An underactive gland will DRY the hair and scalp out. The sweat gland This is the body COOLING system, producing sweat to cool the body when it OVERHEATS. Fill in the gaps using the words listed in the box below. Words: DRY COOLING GREASY SEBUM OVERHEATS

5. Fill in the gaps using the words listed in the box below. The Arrector pili muscle This muscle is attached to the HAIR FOLICLE and to the epidermis. Its purpose is to make the hair stand on end when the body is COLD, also creating a goose pimple, and to lie flat when the body is HOT/WARM. Blood supply The blood supply is to the ROOT of the hair. It carries NUTRIENTS to the root for growth and takes away waste. Therefore, good hair growth depends on NUTRITION and good BLOOD circulation. A head massage during shampooing increases BLOOD flow. Hair follicle This is the pocket in the EPIDERMIS that the HAIR SHAFT protrudes from. Hair papilla This is the ROOT of the hair in the dermis. Words: HAIR FOLICLE, ROOT, HAIR SHAFT, HOT/WARM, COLD, NUTRIENTS, BLOOD, BLOOD, NUTRITION, ROOT, EPIDERMIS.

Words: PAPILLA, CATOGEN, ONE.

11. Read the text under each picture carefully. Fill in the correct words in each space given. The third stage is known as TELOGEN, the resting stage for about THREE TO FOUR months. After this time a new hair starts to grow in the FOLLICLE and if the old hair is still in the FOLLICLE, the new hair pushes it out. Words: FOLLICLE, TELOGEN, THREE TO FOUR, FOLLICLE.
