Infectious diseases only affect the skin, contagious diseases affect internal organs
Contagious diseases spread person-to-person; infectious diseases are caused by pathogens but may not spread easily (Correct answer)
Contagious diseases are caused by fungi; infectious diseases are caused by bacteria
They are identical terms with no distinction

Correct answer: Contagious diseases spread person-to-person; infectious diseases are caused by pathogens but may not spread easily

All contagious diseases are infectious, but not all infectious diseases are contagious—contagious implies easy person-to-person transmission.

Question 64: Onychomycosis is a contraindication for nail enhancements because:

Acrylic monomer kills the fungus, causing a reaction
Filing removes the infection and makes enhancements unnecessary
Covering the nail traps moisture and worsens the fungal infection (Correct answer)
Enhancement products dissolve in the presence of antifungal treatments

Correct answer: Covering the nail traps moisture and worsens the fungal infection

Applying enhancements over a fungal infection traps warmth and moisture, creating an environment that accelerates fungal growth.

Question 65: A client's natural hair is medium brown (level 5). After applying a red permanent color, the result appears too orange. What was the likely cause?

The developer volume was too low to activate the dye
The color was applied to wet hair, diluting the pigment
The color was not lifted enough to neutralize the underlying red-orange pigment (Correct answer)
Too much developer was used

Correct answer: The color was not lifted enough to neutralize the underlying red-orange pigment

Question 68: When performing a virgin relaxer service, where should the product be applied first?

Most resistant area (usually the back crown) (Correct answer)
Hairline and nape first
Ends and then mid-shaft
Entire head simultaneously

Correct answer: Most resistant area (usually the back crown)

A virgin relaxer begins at the most resistant area so it has the most processing time before moving to more fragile areas like the hairline.

Question 69: A client taking isotretinoin (Accutane) wants a facial wax. What is the correct response?

Refuse the service — it is contraindicated (Correct answer)
Apply a thin layer of pre-wax oil and proceed
Proceed with a patch test first
Use hard wax only

Correct answer: Refuse the service — it is contraindicated

Isotretinoin thins the skin and makes it extremely fragile; waxing can lift the skin and cause severe injury, so it is a strict contraindication.

Question 74: When applying nail art foils, what product is typically applied to the nail first to allow the foil to transfer?

Foil adhesive or a tacky uncured gel layer (Correct answer)
Top coat that is fully cured
Nail dehydrator
Base coat only

Correct answer: Foil adhesive or a tacky uncured gel layer

Foil transfers onto a sticky surface—either a dedicated foil adhesive or an intentionally undercured (tacky) gel layer pulls the metallic film off the foil sheet.

Question 75: A client with diabetes requests nail enhancements. The technician's primary concern should be:

Increased risk of slow healing and infection if the skin is accidentally nicked (Correct answer)
Diabetes causing brittleness that prevents acrylic adhesion
The client's blood sugar affecting polish color adhesion
Higher likelihood of allergic reaction to EMA monomer

Correct answer: Increased risk of slow healing and infection if the skin is accidentally nicked

Diabetic clients have compromised circulation and immune response, meaning any small cut or infection can escalate quickly and heal poorly.

Question 76: What is the function of tension during a blow-dry service?

To increase the temperature of the hair
To smooth the cuticle and direct hair into the desired shape (Correct answer)

Question 87: Which behavior best demonstrates professional ethics when a client complains about a previous stylist at the same salon?

Listen empathetically, avoid criticizing colleagues, and focus on the current client's needs (Correct answer)
Agree with the client to build rapport
Tell the client to file a formal complaint
Apologize on behalf of the entire salon staff

Correct answer: Listen empathetically, avoid criticizing colleagues, and focus on the current client's needs

Ethical professionals remain neutral regarding colleagues, focus on solving the current client's concerns, and avoid gossip.

Question 88: A hard gel differs from a soft (soak-off) gel primarily because it:

Must be filed off and cannot be soaked off with acetone (Correct answer)
Cures faster than soft gel
Contains no photoinitiators
Requires a UV lamp only, not an LED lamp

Correct answer: Must be filed off and cannot be soaked off with acetone

Hard gels have a cross-linked polymer structure that acetone cannot penetrate, so they must be filed off for removal.

Question 89: Which of the following best describes informed consent in cosmetology?

1/2 inch (12 mm)
1/8 inch (3 mm)
3/4 inch (19 mm)
1/4 inch (6 mm) (Correct answer)

Correct answer: 1/4 inch (6 mm)

Hair must be at least 1/4 inch long so the wax can grip the hair shaft firmly enough to remove it cleanly from the follicle.

Question 91: A client wants to add red color to dark brown level 4 hair without pre-lightening. What is a realistic outcome?

A subtle red reflect or sheen may be visible in the right light (Correct answer)
The hair will turn a vivid, bright red
No change will occur because dark hair cannot absorb red pigment
The hair will lift significantly to show the red

Correct answer: A subtle red reflect or sheen may be visible in the right light

On dark hair, red pigment deposits but the dark base suppresses vibrancy, resulting in only a subtle red reflect.

Question 92: Which nail enhancement technique uses a brush to apply a mixture of liquid monomer and powder polymer onto the nail?

Acrylic (liquid-and-powder) system (Correct answer)
Dip powder system
Fiberglass/silk wrap system
Gel system

To speed up processing time
To protect the scalp and skin from chemical burns (Correct answer)
To add shine and moisture to the hair
To activate the relaxer formula

Correct answer: To protect the scalp and skin from chemical burns

Base cream creates a protective barrier on the scalp, hairline, and ears to prevent burns from the highly alkaline relaxer chemicals.

Question 103: When blow-drying hair for maximum volume, the nozzle should be directed:

Perpendicular to the section at all times
Away from the scalp at a 45-degree downward angle
Down the hair shaft toward the ends
Upward against the cuticle at the roots (Correct answer)

Correct answer: Upward against the cuticle at the roots

Directing airflow upward at the root lifts the hair away from the scalp and encourages volume at the base.

Question 104: What is a common sign of chemical overprocessing?

Elastic and bouncy curls.
Thicker hair strands.
Brittle and easily breakable hair (Correct answer)
Shiny and strong hair.

Correct answer: Brittle and easily breakable hair

Chemical overprocessing occurs when hair is exposed to chemical solutions for too long or at too high a concentration, leading to severe damage. A common sign is hair becoming brittle, dry, and easily breakable, often feeling gummy or mushy when wet. This indicates that the hair's internal structure has been severely compromised.
