What Do You Know About The Hair?

2.

Which of the following has the highest number of hairs?

Blonde
Redheads
Black haired persons
Brown haired persons

Correct Answer

A. Blonde

Explanation

Blonde hair typically has the highest number of hairs compared to redheads, black-haired persons, and brown-haired persons. This is because blonde hair tends to be finer and thinner in texture, which allows for a higher density of individual hairs. Redheads, black-haired persons, and brown-haired persons usually have thicker and coarser hair, resulting in a lower number of individual hairs.

All of the following determines how straight or curly the hair is except.

The shape of the follicle
The shape of the cortex
The shape of the mucus membrane
The shape of the fiber

Correct Answer

A. The shape of the mucus membrane

Explanation

The shape of the mucus membrane does not determine how straight or curly the hair is. The straightness or curliness of hair is primarily determined by the shape of the follicle, the shape of the cortex, and the shape of the fiber. The mucus membrane, on the other hand, is not directly involved in determining the hair's texture or curl pattern.

Which of the following is one of the major causes of hair loss?

Thyroid imbalance
Cortex
Curticle
None of the above

Correct Answer

A. Thyroid imbalance

Explanation

Thyroid imbalance is one of the major causes of hair loss. The thyroid gland produces hormones that regulate metabolism, growth, and development. When there is an imbalance in thyroid hormone levels, it can disrupt the hair growth cycle and lead to hair loss. Hypothyroidism, or an underactive thyroid, is commonly associated with hair thinning and loss. This occurs because the hair follicles are not receiving enough nutrients and oxygen to support healthy hair growth. Therefore, thyroid imbalance is a significant factor contributing to hair loss.

Which of the following is also known as root of hair?

Hair curticle
Hair follicle
Hair bulb
Hair filament

Correct Answer

A. Hair bulb

Explanation

The hair bulb is also known as the root of the hair. It is the lowest part of the hair follicle, located at the base of the hair shaft. The hair bulb is responsible for producing new cells that make up the hair shaft, and it contains the papilla, which supplies nutrients to the growing hair.

Which of the following is the dominant pigment that results in brown hair?

Pheomelanin
Eumelanin
Neumelanin
Andromelanin

Correct Answer

A. Eumelanin

Explanation

Eumelanin is the dominant pigment that results in brown hair. It is responsible for the dark brown to black color of hair. Pheomelanin, on the other hand, is responsible for the red and yellow pigments in hair. Neumelanin and Andromelanin are not recognized as pigments that contribute to hair color.

The dominant pigment that results in red hair is called

Oligomelanin
Andromelanin
Eumelanin
Pheomelanin

Correct Answer

A. Pheomelanin

Explanation

Pheomelanin is the correct answer because it is the dominant pigment responsible for red hair. It is a type of melanin that produces red and yellow pigments in the hair, skin, and eyes. Pheomelanin is produced in higher amounts in individuals with red hair compared to other types of melanin such as eumelanin, which produces brown and black pigments. The presence of pheomelanin in the hair leads to the characteristic red coloration.

The following are the phases of the growth cycle of hair except

Telogen
Pulagen
Catagen
Anagen

Correct Answer

A. Pulagen

Explanation

The given options are different phases of the hair growth cycle. Telogen is the resting phase, Catagen is the transitional phase, and Anagen is the active growth phase of hair. Pulagen is not a recognized phase of the hair growth cycle, making it the correct answer.

The following are hair typing systems used in the classification of hair

Andre walker system
FIA system
All of the above
None of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "All of the above" because both the Andre Walker system and the FIA system are hair typing systems used in the classification of hair. These systems categorize hair based on its texture, curl pattern, and other characteristics. The Andre Walker system is commonly used to classify hair into four types (straight, wavy, curly, and coily), while the FIA system uses a numerical and alphabetical combination to categorize hair into different types and subtypes. Therefore, "All of the above" is the correct answer as it includes both the mentioned hair typing systems.
