Cosmetology Exam Review

Key point: there is no single cosmetology exam that applies everywhere. Most candidates should prepare for written theory topics, sanitation and infection control, hair services, skin services, nail services, and any practical procedures required by their state.

Try these original cosmetology-style sample questions. These examples reflect common licensing-exam topics, including scientific concepts, infection control, hair care, skin care, nail care, and procedure-based judgment, but they are not actual NIC, PSI, Prometric, or state board exam questions.

1. Infection Control: Single-Use Items

Which item should be discarded after use because it is typically considered single-use?

1. Metal shears
2. Plastic comb
3. Cotton pad
4. Manicure bowl

2. Infection Control: Blood Exposure

During a manicure, a client’s cuticle is accidentally nicked and begins to bleed. Which action should the cosmetologist take first?

1. Continue the service and clean the area at the end.
2. Stop the service and put on gloves before handling the exposure.
3. Dip the implement back into disinfectant and keep working.
4. Wipe the area with a towel used earlier in the service.

3. Scientific Concepts: pH

A product with a pH of 9 is best described as:

1. acidic
2. neutral
3. alkaline
4. sterile

4. Hair Analysis: Porosity

A client’s hair absorbs water and chemical products very quickly. Which hair property is being described?

1. Density
2. Porosity
3. Elasticity

Before applying an oxidative haircolor product, which preliminary test is commonly used to check for a possible allergic reaction?

1. Strand test
2. Predisposition test
3. Elasticity test

6. Haircutting: Elevation

In haircutting, holding the hair at 0 degrees of elevation is most closely associated with which result?

1. A one-length or blunt effect
2. Maximum layering throughout the head
3. Permanent waving
4. Haircolor correction

7. Chemical Texture Services: Neutralizer

In a permanent waving service, what is the main purpose of the neutralizer?

1. To remove all color from the hair
2. To restore the hair’s disulfide bonds into the new curled shape
3. To make the hair permanently immune to humidity
4. To sterilize the rods and end papers

8. Skin Care: Contraindications

Which condition would most likely require postponing a waxing service on the affected area?

3. Avoid servicing the affected nail and recommend that the client seek medical evaluation.
4. Buff the nail aggressively until the discoloration is gone.
