Nail Technician Nail Enhancement Application Questions and Answers

Question 1

When applying acrylic enhancements, what is the primary purpose of using a nail dehydrator before the primer?

Accepted Answer

To temporarily remove surface moisture and oils from the nail plate.

Answer

A nail dehydrator's main function is to temporarily remove moisture and oils from the surface of the natural nail. This creates a clean, dry canvas that allows subsequent products, like primer and the acrylic itself, to adhere more effectively, thus preventing lifting.

Question 2

A nail technician notices that after curing a client's gel polish, a sticky layer remains on the surface. What is the technical term for this layer and what is its primary function?

Accepted Answer

The inhibition layer, which helps subsequent gel layers adhere to one another.

Answer

This sticky or tacky film is called the inhibition layer (or dispersion layer). It forms because oxygen in the air prevents the very top surface of the gel from fully curing. Its primary purpose is beneficial, as it acts as a bonding agent that helps the next coat of gel polish adhere securely, ensuring a strong and durable manicure.

Question 3

In a liquid-and-powder acrylic system, which ingredient is responsible for initiating the polymerization process when activated by heat?

Accepted Answer

Benzoyl peroxide in the polymer.

Answer

The polymer powder in a traditional acrylic system contains an initiator, which is typically benzoyl peroxide. This molecule absorbs energy (from the ambient heat of the room and the client's finger) and breaks apart, starting the chemical reaction (polymerization) that hardens the acrylic.

Question 4

When creating a structured nail enhancement, where should the apex be placed to ensure maximum strength and durability, especially on a longer nail?

Accepted Answer

In the back third of the nail, over the stress area.

Answer

The apex, or the highest point of the enhancement, provides structural support. For optimal strength and to prevent breakage, it should be strategically placed over the stress area, which is the weakest point of the nail. On most nail shapes, this is located in the back third of the nail bed, shifting slightly forward on very long enhancements.

Question 5

A client requests a full set of nail tips with a gel overlay. When sizing the tips, the technician finds that the client's index finger is between two sizes. Which of the following is the correct procedure?

Accepted Answer

Use the larger tip and file the sidewalls to fit the nail plate perfectly.

Answer

When a natural nail is between sizes, it is always best to choose the slightly larger tip. The technician can then carefully file the sides of the tip to achieve a perfect, customized fit from sidewall to sidewall. Using a tip that is too small can cause pressure, discomfort, and lead to the enhancement lifting or breaking.
