Free Cosmetology Review Questions and Answers — Questions and Answers

Question 1: What kind of substance may a dermatologist inject into the skin to strengthen it?

Elastin
Comedone
Collagen (Correct answer)
Melanin

Correct answer: Collagen

Collagen is a protein naturally found in the skin that provides structure, strength, and elasticity. Dermatologists may inject collagen fillers to replenish lost collagen, which helps to plump the skin, reduce wrinkles, and improve overall skin firmness. This process aims to strengthen the skin's underlying support structure, restoring a more youthful appearance.

Question 2: What factors should you consider while choosing shampoo for a client?

the condition of the client's hair and scalp (Correct answer)
the client's regular shampoo
what is available
your favorite

Correct answer: the condition of the client's hair and scalp

When choosing shampoo, it is crucial to consider the client's specific hair and scalp condition. Different shampoos are formulated to address various concerns, such as oily scalp, dry hair, color-treated hair, or dandruff. Selecting a shampoo tailored to these needs ensures optimal cleansing, conditioning, and overall hair health, providing the best results for the client.

Question 3: What constitutes shampoo's major active ingredient?

hydrophilic
lipophilic
water
surfactant (Correct answer)

Correct answer: surfactant

The main active ingredient in shampoo is a surfactant, which stands for 'surface active agent.' Surfactants work by lowering the surface tension of water, allowing it to mix with oils and dirt on the hair and scalp. This enables the shampoo to effectively lift away impurities, which are then rinsed away with water, leaving the hair clean.

Question 4: How long should a hair conditioner be left in place?

10-15 minutes
5-10 minutes
1-5 minutes (Correct answer)
0-3 minutes

Correct answer: 1-5 minutes

Hair conditioner is typically left on the hair for 1-5 minutes to allow its ingredients to penetrate the hair shaft and provide optimal benefits. This timeframe allows the conditioning agents to smooth the cuticle, detangle, and add moisture and shine. Leaving it on for too short a time may reduce its effectiveness, while longer periods are usually unnecessary for standard conditioners.

Question 5: What kind of line will give hair more fullness when it is cut?

diagonal line (Correct answer)
staggered line
horizontal line
vertical line

Correct answer: diagonal line

Diagonal lines in a haircut create movement and can add fullness or blend layers seamlessly. When cut at an angle, diagonal lines can make hair appear fuller by creating a sense of width and volume, especially when used to build up weight in certain areas. This technique is often employed to achieve softer, more voluminous styles, enhancing the hair's body.

Question 6: What instrument would you employ to give the ends a soft appearance?

haircutting shears
texturizing shears
straight razor (Correct answer)
clippers

Correct answer: straight razor

A straight razor is commonly used to create a softer, more feathered appearance at the ends of the hair. The razor's blade slices through the hair strands at an angle, producing a tapered effect that reduces bulk and creates a wispy, diffused finish. This technique is distinct from the blunt cut achieved with shears, offering a more delicate texture.

Question 7: How should a thermal iron to be examined?

sprinkle water on it and see if it sizzles
clamp it to tissue paper or damp towel (Correct answer)
lightly tap it to your hand
place on the hair and feel the hair for heat

Correct answer: clamp it to tissue paper or damp towel

To properly test the temperature of a thermal iron and ensure it's not too hot for the client's hair, you should clamp it onto a piece of tissue paper or a damp towel. If the paper scorches or the towel sizzles excessively, the iron is too hot and needs to cool down. This method prevents accidental damage to the hair, ensuring client safety.

Question 8: What three things make up a pincurl?

circle, stem, curl
curl, balance, stem
contour, base, curl
base, stem, circle (Correct answer)

Correct answer: base, stem, circle

A pincurl is composed of three main parts: the base, the stem, and the circle. The base is the stationary foundation of the curl, attached to the scalp. The stem is the section of hair between the base and the first arc of the circle, determining the curl's direction and mobility. The circle is the actual curl formation, dictating the wave's size and strength.

Question 9: Jessica is giving herself a haircut. When she glances down, she sees that this finger is in charge of her shears' motionless blade. What finger is it on?

Pinky finger
Pinky finger
Ring finger (Correct answer)
Index finger

Correct answer: Ring finger

In professional haircutting, the ring finger is typically inserted into the finger hole of the shears that controls the stationary blade. This grip provides stability and precise control over the moving blade, which is operated by the thumb. It's a fundamental technique that ensures smooth and accurate cuts.

Question 10: Disinfectants don't affect bacteria while they're in the

Spore-forming stage (Correct answer)
Mitosis stage
Vegetative stage
Active stage

Correct answer: Spore-forming stage

Bacteria in the spore-forming stage, also known as the inactive or dormant stage, develop a protective outer shell that makes them highly resistant to disinfectants, heat, and other harsh conditions. Disinfectants are primarily effective against bacteria in their active, vegetative stage. Only sterilization, a higher level of infection control, can effectively destroy bacterial spores.

Question 11: Bacilli are bacteria that have a

Round shape
Curved shape
Corkscrew shape
Rod shape (Correct answer)

Correct answer: Rod shape

Bacilli are one of the three main classifications of bacteria based on their shape, characterized by their rod-like or cylindrical appearance. Other common shapes include cocci (round) and spirilla (spiral). Understanding bacterial shapes is fundamental in microbiology and cosmetology for identifying and controlling potential pathogens.

Question 12: Immune insufficiency syndrome, acquired (aids)

Is caused by HIV virus (Correct answer)
Attacks the nervous system
Is caused by needle use
Is a form of herpes

Correct answer: Is caused by HIV virus

Acquired Immunodeficiency Syndrome (AIDS) is the final, most severe stage of infection with the Human Immunodeficiency Virus (HIV). HIV attacks and destroys CD4 T cells, a type of white blood cell crucial to the immune system, progressively weakening the body's ability to fight off infections and certain cancers. AIDS is not caused by needle use directly, but rather by the transmission of the HIV virus, which can occur through shared needles.

Question 13: Surfaces that can be sanitized include:

Nail plates
Wood and plastic
Nonporous (Correct answer)
Skin

Correct answer: Nonporous

Sanitization and disinfection are effective only on nonporous surfaces because these materials do not absorb liquids, allowing disinfectants to remain on the surface and kill microorganisms. Porous materials like wood, cloth, or skin absorb liquids and harbor bacteria within their pores, making them impossible to properly disinfect or sanitize with standard salon products. Therefore, porous items are often single-use or require specific laundering/sterilization methods.

Question 14: Eyelash hair's scientific name is

Cilia (Correct answer)
Supercilia
Barba
Capilli

Correct answer: Cilia

Cilia is the scientific term specifically used to refer to eyelash hair. Supercilia refers to eyebrow hair, while barba refers to beard hair, and capilli refers to scalp hair. Knowing these specific terms is important for precise communication in the cosmetology and medical fields.

Question 15: Long, dark hair is referred to as

Supercilia
Barba
Vellus
Terminal (Correct answer)

Correct answer: Terminal

Terminal hair is the scientific term for the coarse, pigmented hair found on the scalp, eyebrows, eyelashes, and body after puberty. It is distinct from vellus hair, which is fine, short, and often unpigmented 'peach fuzz.' Understanding the different types of hair is crucial in cosmetology for various treatments and services.

Question 16: What is one of the major elements required for good health?

Clothing
Diet (Correct answer)
Coworkers
Training

Correct answer: Diet

A balanced and nutritious diet is a fundamental pillar of good health, providing the essential vitamins, minerals, and energy the body needs to function properly. While clothing, coworkers, and training are important aspects of life, they do not directly contribute to physiological health in the same critical way as diet. Proper nutrition supports immune function, energy levels, and overall well-being.
