WAEC/NECO Cosmetology Syllabus Revision SS3 Beauty & Cosmetology Lesson Note

The Foundations & Tools of the Trade

To pass your exam, you must first master the “Basics.” WAEC and NECO examiners often ask questions about the classification of tools and how we keep them safe.

1. Classification of Tools:

• Cutting Tools: Scissors, razors, and clippers. (Always keep them sharp; a dull blade is more dangerous than a sharp one).
• Non-Cutting Tools: Combs, brushes, rollers, and pins.
• Electrical Tools: Hand dryers, hooded dryers, and curling irons.

2. Hygiene and Safety (The “Golden Rules”):

• Sanitization: Cleaning with soap and water to remove visible dirt.
• Disinfection: Using chemicals (like alcohol or Izal) to kill germs on tools.
• Sterilization: Using high heat (Autoclave) to kill all life forms, including spores.
• Safety First: Always keep the floor dry to avoid slips, and never plug too many electrical items into one socket to avoid fires.

3. Professional Ethics: A cosmetologist must be punctual, have good breath, clean nails, and keep client secrets. Your behavior is part of your grade!

Hair Care, Science, and Styling

This is a large part of the syllabus. You need to understand how hair grows and how we change its structure.

1. Hair Structure:

• Cuticle: The outer layer (looks like fish scales). It protects the hair.
• Cortex: The middle layer. This is where the strength and color (melanin) live.
• Medulla: The very center (sometimes missing in fine hair).

2. Hair Disorders to Identify:

• Dandruff (Pityriasis): Flaky skin on the scalp.
• Alopecia: Abnormal hair loss or baldness.
• Tinea Capitis: Ringworm of the scalp (contagious!).
• Fragilitas Crinium: Brittle hair or split ends.

3. Chemical Services:

• Relaxing: Using “Sodium Hydroxide” (Lye) or “Ammonium Thioglycolate” (No-Lye) to straighten hair. Always apply a “Base Cream” to protect the scalp.
• Neutralizing: This is the most important step after relaxing. It stops the chemical action and brings the hair back to its normal pH.

Skin Care and Professional Makeup

The examiners want to see that you understand skin types and how to enhance features correctly.

1. Skin Types:

• Oily: Shiny, enlarged pores, prone to pimples.
• Dry: Tight feeling, flaky, small pores.
• Combination: Oily on the “T-Zone” (forehead, nose, chin) and dry on the cheeks.

2. Facial Treatment Steps:

1. Cleansing: Removing dirt/makeup.
2. Exfoliation: Removing dead skin cells.
3. Steaming: Opening the pores.
4. Extraction: Removing blackheads.
5. Massage: Improving blood flow.
6. Mask/Toning: Closing the pores and soothing the skin.

3. Makeup Application Order:

• Prep/Prime → Foundation → Concealer → Powder → Brows → Eyes → Lips → Setting Spray.
• Highlighting: Using a lighter shade to bring features “forward” (like the bridge of the nose).
• Contouring: Using a darker shade to create shadows and “recede” features (like the hollows of the cheeks).

Nail Care (Manicure and Pedicure)

Nails are delicate. You must know the parts of the nail and how to treat them without causing pain or infection.

1. Anatomy of the Nail:

• Nail Plate: The visible part we paint.
• Free Edge: The part of the nail that hangs over the finger.
• Matrix: The “Mother” of the nail where growth starts. If the matrix is damaged, the nail may never grow back properly.
• Cuticle: The small flap of skin at the base that protects the matrix.

2. Common Nail Shapes: Oval, Square, Squoval (Square with rounded edges), and Almond.
3. Manicure Procedure:

• Remove old polish → File/Shape → Soak → Cuticle care → Massage → Buffing/Painting.
• Safety Note: Never cut the cuticle too deep, as it can lead to a “Paronychia” (infection of the skin around the nail).

Entrepreneurship and Exam Strategy

The final part of your exam will test your ability to run a business and how well you read the questions.

1. Starting a Beauty Business:

• Market Survey: Asking people what they need before you open.
• Location: Choosing a place with good electricity, water, and many people passing by.
• Pricing: Making sure you cover your costs (rent, light, products) and still make a profit.

2. Handling “Tricky” Exam Questions:

• “Identify”: Just name the item.
• “Describe”: Give details about how it looks or works.
• “Differentiate”: Show the difference between two things (e.g., “Relaxing straightens hair while Perming curls it”).
• Diagrams: In the practical exam, always label your diagrams clearly with straight lines. Don’t let your labels cross each other.

3. Final Revision Tip: Make sure you know your pH scale. Skin and hair are naturally slightly acidic (around 4.5 to 5.5). Most chemicals we use are Alkaline. Understanding this balance is the key to many “Chemistry of Cosmetology” questions.
