CHAPTER 9 – HAIR STRUCTURE & GROWTH
WHY THIS CHAPTER MATTERS
Hair structure and growth theory guide safe hair-removal services. Licensing examinations frequently test an esthetician’s ability to identify hair anatomy, growth phases, and factors affecting growth, especially when determining timing, safety, and expected results for waxing and other temporary hair-removal methods.
Understanding what hair is, where it grows, and how it grows prevents skin injury and improper service decisions.
STRUCTURE OF THE HAIR
Hair is a keratinized fiber that grows from a follicle in the skin.
MAIN PARTS OF HAIR
- Hair Shaft – the visible portion above the skin
- Hair Root – the portion below the skin
- Hair Follicle – the tube-like pocket in the skin from which hair grows
Esthetic services affect the hair shaft, not permanent growth structures.
STRUCTURE OF THE HAIR FOLLICLE
The hair follicle includes:
- Hair bulb – the thickened base of the root
- Dermal papilla – supplies nutrients via blood vessels
- Matrix – where new hair cells are produced
- Arrector pili muscle – causes hair to stand when cold or frightened
- Sebaceous gland – produces oil (sebum)
Licensing exams often ask which structures nourish hair.
COMPOSITION OF HAIR
Hair is primarily composed of:
- Keratin – a fibrous protein
Hair does not contain nerves or blood vessels.
TYPES OF BODY HAIR
Vellus Hair
- Fine
- Soft
- Light in color
- Covers most of the body
Terminal Hair
- Coarse
- Thick
- Darker
- Found on scalp, brows, lashes, and certain body areas
Waxing commonly removes terminal hair, but vellus hair may also be removed.
HAIR GROWTH CYCLE (CRITICAL EXAM TOPIC)
Hair grows in three repeating phases.
ANAGEN PHASE (GROWTH PHASE)
- Active growth phase
- Hair is attached to the dermal papilla
- Longest phase
- Hair removal during this phase yields the best results
CATAGEN PHASE (TRANSITION PHASE)
- Short transitional period
- Hair detaches from the papilla
- Growth slows
TELOGEN PHASE (RESTING PHASE)
- Hair is shed
- Follicle rests before re-entering anagen
Licensing exams often ask:
- Which phase provides best waxing results
- Which phase involves shedding
FACTORS AFFECTING HAIR GROWTH
Hair growth can be influenced by:
- Genetics
- Hormones
- Age
- Nutrition
- Health conditions
- Medications
Estheticians do not alter permanent hair growth.
DIRECTION OF HAIR GROWTH
Hair grows in specific directions depending on body area.
Understanding growth direction is critical for:
- Proper wax application
- Safe hair removal
- Reduced skin irritation
SCOPE OF PRACTICE REMINDER
Estheticians:
- Perform temporary hair removal
- Do not provide permanent hair removal
- Do not diagnose hair growth disorders
COMMON LICENSING EXAM TRAPS
- Confusing hair shaft with follicle
- Incorrect growth phase identification
- Assuming hair removal affects permanent growth
- Ignoring growth direction
- Misidentifying vellus vs terminal hair

CHAPTER 10 – WAXING & TEMPORARY HAIR REMOVAL
WHY THIS CHAPTER MATTERS
Waxing is a common esthetics service and one of the most frequently tested areas on licensing examinations. Exam questions focus heavily on client safety, contraindications, temperature control, sanitation, and correct procedure rather than speed or technique.
Improper waxing can cause burns, skin lifting, infection, and scarring. Understanding when waxing is safe and when it must be refused is essential to professional practice.
PURPOSE OF WAXING
Waxing is a form of temporary hair removal that removes hair from the follicle.
Waxing:
- Does not permanently remove hair
- Does not alter hair growth cycles
- Must be performed within scope and safety guidelines
TYPES OF WAX
Soft Wax
- Removed with a cloth or paper strip
- Applied in a thin layer
- Commonly used on larger areas
Hard Wax
- Hardens and is removed without strips
- Applied in thicker layers
- Often used on sensitive areas
Licensing exams may test differences in application and removal.
WAX TEMPERATURE CONTROL (CRITICAL)
Wax temperature must be:
- Warm enough to spread easily
- Never hot enough to burn the skin
Safety Rules
- Always test wax temperature before application
- Never double-dip applicators
- Do not leave wax unattended while heating
Burns are a common exam topic.
SANITATION DURING WAXING
Sanitation rules apply throughout the service:
- Wash hands before and after service
- Wear gloves when appropriate
- Use clean applicators
- Dispose of single-use items properly
- Disinfect nonporous tools
Failure to follow sanitation procedures is a licensing violation.
PROPER WAXING PROCEDURE (GENERAL)
- Client consultation and contraindication check
- Cleanse and dry the area
- Apply wax in direction of hair growth
- Remove wax against hair growth
- Apply pressure to soothe skin
- Apply post-wax product as appropriate
Exams often test direction of application and removal.
CONTRAINDICATIONS FOR WAXING (HIGHLY TESTED)
Waxing must be refused or postponed when the client has:
- Sunburn
- Open wounds
- Inflamed or infected skin
- Contagious skin conditions
- Recent chemical peels
- Recent use of certain medications (e.g., strong exfoliants)
When in doubt, do not wax.
SKIN LIFTING & TRAUMA
Skin lifting occurs when:
- Wax is too hot
- Skin is too fragile
- Improper removal technique is used
Prevention
- Proper temperature control
- Correct tension on the skin
- Avoid waxing fragile areas
POST-WAX CARE
Post-wax care includes:
- Calming products
- Avoiding heat or sun exposure
- Client education on aftercare
Aftercare instructions protect the client and the service outcome.
WHEN TO STOP OR REFUSE A WAX SERVICE
A wax service must be stopped if:
- The client experiences burning
- Skin reaction occurs
- Bleeding is present
- Client discomfort becomes significant
Stopping a service is a professional responsibility.
COMMON LICENSING EXAM TRAPS
- Waxing sunburned skin
- Applying wax against hair growth
- Removing wax in wrong direction

CHAPTER 11 – TWEEZING & DEPILATORIES
WHY THIS CHAPTER MATTERS
Tweezing and depilatories are forms of temporary hair removal that may appear simple, but they carry safety risks when performed improperly. Licensing examinations frequently test an esthetician’s understanding of proper use, sanitation, contraindications, and client protection related to these services.
Questions often focus on when these methods are appropriate and when they must be avoided.
TWEEZING
Definition
Tweezing is the removal of hair from the follicle using sanitized tweezers.
COMMON USES OF TWEEZING
- Shaping eyebrows
- Removing stray hairs
- Finishing after waxing
Tweezing is typically used on small areas only.
SANITATION REQUIREMENTS
