Question 1Hair fibre, growth and material behavior

Which layer of the hair is the outermost protective layer made of overlapping, flat, scale-like cells?

  1. Cortex
  2. Medulla
  3. Cuticle Correct answer.
  4. Dermal papilla

Explanation

The cuticle is the outermost layer of the hair shaft. It is formed of flat, translucent cells that overlap like roof tiles, and its job is to protect the inner cortex and help the hair retain moisture.

Question 2Hair fibre, growth and material behavior

Which layer of the hair contains most of the keratin and the melanin that determines natural hair colour?

  1. Cuticle
  2. Cortex Correct answer.
  3. Medulla
  4. Hair bulb

Explanation

The cortex is the thick middle layer that makes up most of the hair. It contains keratin fibres that give strength and elasticity, and melanin pigment that determines the natural colour of the hair.

Question 3Hair fibre, growth and material behavior

What is the central, often soft and sometimes absent, innermost core of a hair strand called?

  1. Medulla Correct answer.
  2. Cuticle
  3. Follicle
  4. Cortex

Explanation

The medulla is the innermost core of the hair shaft. It is soft and air-filled and may be absent altogether in fine or light hair, while it is most evident in thick, coarse hair.

Question 4Hair fibre, growth and material behavior

Which protein is the main structural component of hair, skin and nails?

  1. Collagen
  2. Keratin Correct answer.
  3. Melanin
  4. Elastin

Explanation

Keratin is the tough, fibrous protein that forms the main structure of hair, the outer skin and the nails, giving them their strength and resilience.

Question 5Hair fibre, growth and material behavior

During which phase of the hair growth cycle is the hair actively growing?

  1. Telogen
  2. Catagen
  3. Anagen Correct answer.
  4. Exogen

Explanation

Anagen is the active growing phase of the hair cycle, during which cells in the bulb divide rapidly to produce the hair shaft. It is the longest phase, lasting several years on the scalp.

Question 6Hair fibre, growth and material behavior

Which phase of the hair growth cycle is the resting phase that ends in the hair being shed?

  1. Anagen
  2. Telogen Correct answer.
  3. Catagen
  4. Mitosis

Explanation

Telogen is the resting phase of the hair cycle. The follicle is inactive, the hair is held loosely, and at the end of this phase the old hair is shed before a new anagen phase begins.

Question 7Hair fibre, growth and material behavior
