CLASS 10TH BEAUTY AND WELLNESS (UNIT 2 ) BASIC DEPILATION SERVICES

 

BASIC DEPILATION SERVICES 

Introduction

Basic depilation services cover the methods and science of removing unwanted hair from different parts of the body. A good understanding of hair types, hair structure, and the hair growth cycle helps a beautician choose the right removal method and give safer, longer-lasting results.
Methods of Removing Unwanted Hair
Hair removal methods are broadly classified into two groups:

1. Depilation (surface removal)

- Shaving: 

Cuts hair at skin level using a razor or electric shaver. Fast and inexpensive but regrowth is quick.

- Trimming: 

Shortens hair with scissors or trimmers; used when full removal is not desired.

- Depilatory creams:

 Chemical products that dissolve the hair shaft above skin level; perform a patch test before use.

2. Epilation (root removal / longer-lasting)

- Waxing: 

Warm or hard wax removes hair from the root; results last 3–6 weeks.

- Threading: 

A cotton thread pulls hair out from the follicles; precise for brows and upper lip.

- Tweezing/pinching: 

Individual hairs removed with tweezers; used for small areas.

- Sugaring: 

A sugar-based paste removes hair similar to waxing; often gentler.

Permanent/long-term methods: 

Electrolysis (destroys follicle electrically) and laser hair removal (uses light energy) — these require trained professionals and multiple sessions.

3. Bleaching

Bleaching is not hair removal but lightens hair to make it less visible.

Types of Hair

- Lanugo:

 Fine, soft hair in fetus or newborns (not usually relevant to salon work).
Vellus hair: Short, fine, pale “peach fuzz” found on most of the body; delicate techniques are needed.

- Terminal hair: 

Thick, pigmented hair found on scalp, eyebrows, eyelashes, underarms, pubic area and on adult male faces/limbs. Most salon removal methods target terminal hair.

Structure of Hair (Basic internal anatomy)

- Hair shaft:

 The visible part above the skin; composed of three layers — cuticle (outer protective layer), cortex (middle layer providing strength and colour), medulla (central core, present in thick hairs).

- Hair root:

 The part under the skin within the follicle.

- Hair follicle:

 A tubular invagination of the epidermis that anchors the hair.

- Bulb: 

The bulb at the base contains living cells that divide to form hair.

- Dermal papilla: 

At the base of the bulb; contains blood vessels that nourish the hair and control growth.

- Accessory structures: 

Sebaceous glands (secrete oil) and arrector pili muscle (causes hair to stand).

Hair Growth Cycle

Hair growth follows a cycle of three main phases:

- Anagen (growth phase):

 Active growth; can last years on scalp (2–6 years) and shorter on body hair. Hair removal is most effective during early anagen.

- Catagen (transition phase): 

Short transition (about 2–3 weeks) when growth stops and follicle shrinks.

Telogen (resting/shedding phase): 

Follicle rests for ~2–4 months before hair falls out and a new anagen phase begins.
Because hairs are in different phases at any time, repeated treatments are needed for long-term reduction.

Importance for a Beautician

- Selecting correct method based on hair type, skin sensitivity, client age and area.
- Understanding growth cycle helps schedule repeated treatments (e.g., waxing every 3–6 weeks).
- Knowledge of structure and related skin glands prevents complications and enables correct aftercare.

Precautions and Aftercare (Short)

- Do a patch test for chemical depilatories and new clients.
- Avoid waxing/threading on inflamed, sunburnt, infected or broken skin.
- Use sterilized tools, disposable strips, gloves and clean workspace.
- Aftercare: apply soothing gel (aloe vera), avoid hot baths, sun, harsh scrubs and perfumes for 24 hours; exfoliate gently after 48–72 hours to prevent ingrown hairs.

Questions & Answers

1: What is depilation?
Ans: Depilation removes hair above the skin surface (e.g., shaving, creams).

2: What is epilation?
Ans: Epilation removes hair from the root (e.g., waxing, threading, tweezing).

3: Name two types of hair.
Ans: Vellus hair and terminal hair.

4: What are the three layers of the hair shaft?
Ans: Cuticle, cortex, medulla.

5: Which phase of hair growth is best targeted for permanent reduction?
Ans: Anagen (active growth) phase.

6: Why is a patch test important?
To check for allergic reactions to depilatory creams or new wax.

7: Give two immediate aftercare tips post-waxing.
Ans: Apply soothing gel; avoid sun and hot showers for 24 hours.

8: Explain the hair growth cycle and its relevance to hair removal.
Ans.:  Describe Anagen, Catagen, Telogen with durations and explain that not all hairs are in same phase, so multiple sessions are needed; anagen is ideal for laser/electrolysis.

9: Differentiate between soft wax and hard wax.

Ans: Soft wax is applied thinly and removed with strips, good for large areas; hard wax is applied thicker, sets and is removed without strips, gentler on sensitive areas and less painful.

10 : Describe the structure of hair and role of the dermal papilla.
Ans: Explain shaft (cuticle/cortex/medulla), root, follicle, bulb; dermal papilla supplies nutrients, controls growth; damage to papilla affects hair production.

11: List precautions to avoid ingrown hair after waxing and how to prevent them.
Ans:  Cleanse skin, exfoliate after 48–72 hours, moisturize, avoid tight clothing immediately, recommend regular gentle exfoliation and correct waxing technique.

Important Questions with Answers 

Q1. Explain in detail the different methods of removing unwanted hair. Write advantages and disadvantages of each.

Answer:  There are two main methods of hair removal:

Depilation – removing hair from the surface of the skin.

Examples: shaving, depilatory creams.

Advantages: quick, painless, inexpensive.

Disadvantages: hair regrows in 2–3 days, chances of cuts, skin darkening, and rough texture.

Epilation – removing hair from the root.

Examples: waxing, threading, tweezing, laser.

Advantages: hair regrows slowly (3–4 weeks), softer regrowth, skin looks smooth.

Disadvantages: can be painful, risk of redness, costlier than depilation.

Q2. Describe the hair growth cycle with the help of a diagram. Why is it important for beauty professionals to understand this cycle?

Answer:  Hair growth occurs in three stages:

Anagen (Growth Phase) – Hair is actively growing from the follicle.

Catagen (Transition Phase) – Growth stops and the follicle shrinks.

Telogen (Resting Phase) – Hair falls out naturally and new hair begins to grow.

👉 Importance:

Helps professionals decide the right time for waxing or other services.

Prevents damage to the skin.

Ensures effective, long-lasting results.

Q3. Explain the internal structure of hair with a neat diagram and describe the function of each part.

Answer:  Hair has two main parts:

Hair Shaft – visible part above skin, made of keratin.

Hair Root – inside the skin, includes follicle and bulb.

Layers of Hair:

Cuticle – outer layer, protects hair.

Cortex – middle layer, gives strength, elasticity, and color (melanin present).

Medulla – central part, soft and spongy.

👉 Functions: protect skin, provide appearance, regulate body temperature.

Q4. Differentiate between Depilation and Epilation with examples.

Answer:  Depilation: Hair removed only from skin surface. Example: shaving, hair removal creams.

Epilation: Hair removed from the root. Example: waxing, threading, tweezing.

Q5. Write a short note on the two main types of human hair.

Answer:  Vellus Hair – short, fine, soft, light-colored hair found on face and body.

Terminal Hair – thick, long, pigmented hair found on scalp, eyebrows, eyelashes, underarms, etc.

Q6. Why is waxing considered more effective than shaving?

Answer:  Waxing removes hair from the root, shaving cuts only at the surface.

Waxing results last 3–4 weeks, shaving lasts 2–3 days.

Waxing gives smoother skin, shaving may cause roughness and cuts.

Q7. Name the three stages of hair growth cycle.

Answer: Anagen, Catagen, Telogen.

Q8. Write any two advantages of threading.

Answer:  Gives precise shape to eyebrows.

Regrowth is slower compared to shaving.

Q9. What is melanin and how does it affect hair colour?

Answer:  Melanin is a natural pigment found in the cortex of hair.

More melanin = dark hair.

Less melanin = light or grey hair.

Q10. What is the scientific term for the hair root covering?

Answer: Hair follicle.

11. Which part of the hair is visible above the skin surface?

Answer: Hair shaft.

Q12. Name one temporary method and one permanent method of hair removal.

Answer: Temporary: Shaving.

Permanent: Laser hair removal.

Q13. Write full form of CBSE.

Answer: Central Board of Secondary Education.

Q14. Which layer of hair contains keratin?

Answer: Cortex.
