Try these 10 sample questions from the National Barber 1 (No Chemical) Theory Examination practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

  1. 1A barber is comparing product labels and finds one product described as a sanitizer. Under the CDC infection-control glossary, what does a sanitizer accomplish?

    1. A. It reduces bacterial contaminants to levels judged safe by public health requirements
    2. B. It destroys disease-causing pathogens on objects but might not kill bacterial spores
    3. C. It renders an item free of all viable microorganisms through a validated process
    4. D. It prevents or arrests microbial growth when the preparation is applied to living tissue

    Answer: A

    Explanation: CDC defines a sanitizer as an "Agent that reduces the number of bacterial contaminants to safe levels as judged by public health requirements." Sanitizing lowers contamination to a safe level; it does not promise the broader pathogen kill of disinfection (option B), the total kill of sterilization (option C), or the living-tissue use that defines an antiseptic (option D).

    Reference: Glossary - Guideline for Disinfection and Sterilization in Healthcare Facilities (2008), CDC — Glossary, entry "Sanitizer"

  2. 2A barber is buying a new hand-held blow dryer for the station. Under the Consumer Product Safety Commission's rule, a hand-supported hair dryer that lacks which feature is deemed a substantial product hazard?

    1. A. A polarized plug that has one prong wider than the other
    2. B. A power cord that meets a minimum wire size requirement
    3. C. Integral immersion protection meeting the UL safety standard
    4. D. Overcurrent protection that limits the current it can draw

    Answer: C

    Explanation: Under 16 CFR 1120.3, the products deemed substantial product hazards include "(a) Hand-supported hair dryers that do not provide integral immersion protection in compliance with the requirements of section 5 of UL 859, or section 6 of UL 1727". Polarization and minimum wire size appear in the same rule as criteria for extension cords, and overcurrent protection appears as a criterion for seasonal and decorative lighting products, not hair dryers.

    Reference: 16 CFR 1120.3 - Products deemed to be substantial product hazards (eCFR) — 16 CFR 1120.3(a)

  3. 3During a hair analysis, a barber rolls a single strand between the fingers to judge whether it is coarse, medium, or fine. According to NIC's sample examination key, what is the diameter of a single strand of hair called?

    1. A. Density
    2. B. Growth pattern
    3. C. Porosity
    4. D. Texture

    Answer: D

    Explanation: The NIC Barber 1 (No Chemical) Theory CIB includes the sample item "The diameter of a single strand of hair is also called" with the options growth pattern, porosity, density, and texture, and its answer key gives D, "texture." Density is the amount of hair on the scalp, porosity is the hair's ability to absorb moisture, and growth pattern is the direction in which hair grows.

    Reference: NIC National Barber 1 (No Chemical) Theory Examination CIB — Sample Questions, item on hair strand diameter, and Answer Key

  4. 4During a skin evaluation before a shave, a barber sees fine, dilated capillaries visible beneath the surface of the client's cheeks. According to NIC's sample examination key, what are these called?

    1. A. Seborrhea
    2. B. Keratoma
    3. C. Telangiectasia
    4. D. Dehydration

    Answer: C

    Explanation: NIC's Esthetics Theory CIB includes the sample item "Dilated capillaries that can be seen beneath the surface of the skin are known as" with options seborrhea, keratoma, telangiectasia, and dehydrated, and its answer key gives C, telangiectasia. MedlinePlus Genetics likewise describes visible clusters of blood vessels as telangiectasia in rosacea.

  5. 5A barber disinfects clipper blades with an EPA-registered disinfectant. According to CDC's definitions, how does the result of disinfection differ from sterilization?

    1. A. Disinfection lowers bacterial counts to safe levels but leaves enveloped viruses such as HIV active
    2. B. Disinfection kills every microbial form, including bacterial spores, once the contact time is reached
    3. C. Disinfection kills most recognized pathogens but not necessarily all forms, such as bacterial spores
    4. D. Disinfection is meant for living tissue, while sterilization is meant only for tools and other objects

    Answer: C

    Explanation: CDC states that "Disinfection is less lethal than sterilization because it destroys most recognized pathogenic microorganisms but not necessarily all microbial forms (e.g., bacterial spores)." Killing every form, spores included, describes sterilization, not disinfection. The glossary also notes that lipid viruses such as HIV are "generally easily inactivated by many types of disinfectants," so the claim that enveloped viruses stay active is wrong, and disinfectants are applied to inanimate objects rather than living tissue.

    Reference: Glossary - Guideline for Disinfection and Sterilization in Healthcare Facilities (2008), CDC — Glossary, entries "Disinfection" and "Lipid virus"

  6. 6A barber's plugged-in blow dryer slips off the counter into a filled shampoo bowl. According to CPSC, how does a ground-fault circuit interrupter (GFCI) on that outlet protect the barber?

    1. A. It cuts power only when the circuit draws more current than the wiring allows
    2. B. It only keeps the plug from being inserted backward into the wall outlet
    3. C. It monitors electricity flowing in the circuit and shuts power in milliseconds
    4. D. It only limits the dryer's outlet air temperature when the heater overheats

    Answer: C

    Explanation: CPSC explains: "The GFCI shock protector constantly monitors electricity flowing through a circuit. If the hair dryer or any electric appliance accidentally topples into the sink or tub, the GFCI will shut down the power in milliseconds to protect the consumer against electrocution or severe electrical burn injuries." Overcurrent protection, plug polarization, and heat limiting are different safety features that do not respond to a ground fault.

  7. 7Before cutting, a barber parts the hair in several places to judge how much hair grows on each area of the scalp. According to NIC's sample examination key, what is the term for the amount of hair per square inch on the scalp?

    1. A. Elasticity
    2. B. Porosity
    3. C. Texture
    4. D. Density

    Answer: D

    Explanation: NIC's Natural Hair Styling Theory CIB includes the sample item "Which of the following is the term for the amount of hair per square inch on the scalp?" with options elasticity, texture, density, and porosity, and its answer key gives density. Texture refers to the diameter of a single strand, as in the barber CIB's sample item.

  8. 8A middle-aged client with fair skin has frequent facial flushing, small red lines under the skin, and acne-like bumps on the cheeks and nose. According to MedlinePlus, which long-term skin disease do these symptoms describe?

    1. A. Rosacea
    2. B. Psoriasis
    3. C. Vitiligo
    4. D. Impetigo

    Answer: A

    Explanation: MedlinePlus describes rosacea as "a long-term disease that affects your skin and sometimes your eyes" and notes that "In most cases, rosacea only affects the face. Symptoms can include: Frequent redness of the face, or flushing Small, red lines under the skin" along with acne and a swollen nose. Psoriasis causes thick scaly patches, vitiligo causes white patches, and impetigo is a crusting bacterial infection.

    Reference: Rosacea - MedlinePlus (National Library of Medicine) — Summary, list of symptoms

  9. 9While a barber is shaving a client who has a bleeding nick, a drop of the client's blood splashes into the barber's mouth. Under OSHA's Bloodborne Pathogens standard, what is the required response?

    1. A. Finish the service, then rinse the mouth with water at the end of the workday
    2. B. Flush the mouth's mucous membranes with water immediately or as soon as feasible
    3. C. Swab the inside of the mouth with an antiseptic instead of flushing it with water
    4. D. Report the splash to the employer and wait for approval before any rinsing occurs

    Answer: B

    Explanation: OSHA requires that employees "wash hands and any other skin with soap and water, or flush mucous membranes with water immediately or as soon as feasible following contact of such body areas with blood or other potentially infectious materials." The mouth is a mucous membrane, so the barber flushes it with water right away. Delaying until the end of the day, substituting an antiseptic swab, or waiting for approval before rinsing does not meet the immediate-flush requirement; reporting follows the first-aid step rather than replacing it.

    Reference: 29 CFR 1910.1030 - Bloodborne Pathogens (OSHA) — 29 CFR 1910.1030(d)(2)(vi)

  10. 10NIC's published sample items for this examination include one on shear styles. According to the NIC answer key, which feature do all French-style shears have?

    1. A. A finger brace
    2. B. Tight pivots
    3. C. Cobalt metal blades
    4. D. Manufacture in France

    Answer: A

    Explanation: The NIC Barber 1 (No Chemical) Theory CIB sample item reads "All French style shears" with options including "B. have a finger brace." and the answer key gives B for that item. The other options in the NIC item (cobalt metal, being made in France, tight pivots) are not what defines the style.
