Free Cosmetology State Board Practice Test (25 Questions)
This free cosmetology state board practice test has 25 questions across the areas written exams focus on most: infection control and safety, hair and scalp, skin and nail care, chemical services, anatomy, client consultation and state laws.
Sanitation and infection control appear in every cosmetology written exam, so they make up a large share of this test. Your state may also require a practical exam; check your candidate bulletin.

- 1Sanitation & Safety
A licensee identifies a needlestick from an unidentified sharp during cleanup. The licensee should:
Answer: A. Wash, document, and seek medical evaluation per protocol
Needlesticks require immediate decontamination, documentation, and medical evaluation following bloodborne pathogen exposure protocols. Some employers refer to occupational health for risk assessment.
- 2Sanitation & Safety
A stylist sees small white specks attached to the hair shafts of a client and live insects moving in the scalp. This is most likely:
Answer: B. Pediculosis (head lice)
Eggs (nits) attached to hair shafts and visible live insects strongly indicate pediculosis. The licensee must refuse service and refer to a healthcare provider for treatment.
- 3Anatomy & Physiology
The skin's natural acid mantle has a pH around:
Answer: C. 4.5–5.5 (slightly acidic)
The acid mantle is composed of sebum, sweat, and skin cells with pH ~4.5–5.5. It supports the microbiome and protects against pathogens. Alkaline products can disrupt the mantle.
- 4Sanitation & Safety
Most state boards require salon shampoo bowls to provide:
Answer: D. Hot and cold running potable water
Salons must have hot and cold running potable water at shampoo bowls and hand-washing stations. Standing or static water is generally not acceptable.
- 5Sanitation & Safety
A pedicure technician must clean and disinfect a whirlpool foot spa:
Answer: A. After each client and at the end of the day
Most state boards require foot spa cleaning and disinfection between every client and an additional, more thorough end-of-day disinfection (often including a longer soak with disinfectant).
- 6Client Consultation
A consultation includes a 'face shape analysis.' A round face is generally:
Answer: B. Made more oval by adding height on top and reducing side width
Round faces are flattered by styles that add height (lengthening) and reduce side width (slimming). Oval is the 'ideal' face shape, around which the rules are designed.
- 7Chemistry & Services
In hair color, 'level' refers to depth (1–10). 'Tone' refers to:
Answer: C. Warm/cool/neutral character of the color
Tone describes the warm (gold/copper/red), cool (ash/violet/blue), or neutral character of a color independent of its level (depth).
- 8Laws & Regulations
An esthetician's scope of practice generally covers:
Answer: D. Skin care of face, neck, and décolletage
Estheticians focus on non-medical skin care: facials, exfoliation, hair removal (waxing), makeup, and superficial skin treatments. Medical procedures require a medical license.
- 9Sanitation & Safety
After disinfection, salon implements should be:
Answer: A. Stored in a clean, covered, dry container
Disinfected implements must be stored in a clean, covered, dry container clearly separated from soiled tools to prevent recontamination before the next service.
- 10Sanitation & Safety
A stylist uses a fine spray (atomizer) for hair products. The principal sanitation concern is to:
Answer: B. Ensure spray nozzles are routinely cleaned and sanitized
Atomizer nozzles can clog and harbor bacteria. They should be cleaned, sanitized, and rinsed between clients (or between product batches), and refilled with fresh product.
- 11Sanitation & Safety
A pedicure tub had standard cleaning between clients but a client develops a mycobacterial skin infection. The likely failure was:
Answer: C. Failure to remove and disinfect the foot-bath jets
Pedicure foot-bath jets and pumps can harbor mycobacteria. Cleaning and disinfecting after each client — including disassembled jets — and weekly full disinfection prevent outbreaks.
- 12Sanitation & Safety
Workers with potential exposure to bloodborne pathogens are recommended (and often required by employers) to be vaccinated against:
Answer: D. Hepatitis B virus (HBV)
An effective HBV vaccine exists and is offered to workers with bloodborne exposure under OSHA's 1910.1030 standard. Vaccines for HCV and HIV do not exist; tetanus is unrelated.
- 13Hair & Scalp
The scientific study of hair, its diseases, and its care is called:
Answer: A. Trichology
Trichology is the dedicated scientific study of hair and scalp. Dermatology covers skin generally; pathology studies disease; histology studies tissues at the microscopic level.
- 14Chemistry & Services
The neutralizer used after a thio permanent wave:
Answer: B. Is oxidative and reforms disulfide bonds in new shape
Neutralizer (typically hydrogen peroxide) oxidizes the broken disulfide bonds back into place around the rod, locking in the new curl shape. Insufficient neutralization causes loss of curl.
- 15Sanitation & Safety
A salon owner asks which of her decontamination methods will destroy bacterial spores in addition to vegetative bacteria. The answer is:
Answer: C. Sterilization (e.g., autoclave or chemical sterilant)
Only sterilization reliably destroys all microbial life including spores. Hospital-grade disinfectants kill many pathogens but typically do not eliminate spores.
- 16Shaving & Barbering
To minimize razor irritation, a second-pass close shave is generally performed:
Answer: D. Across or against the grain after re-lathering
After the first with-grain pass, the barber re-lathers and shaves across or against the grain for closeness. Re-lathering reduces friction and irritation.
- 17Sanitation & Safety
A cosmetologist completes a wax service using a wooden applicator stick. After use, the stick should be:
Answer: A. Discarded as a single-use porous item
Wooden applicator (orangewood) sticks and similar porous, single-use items cannot be effectively disinfected and must be discarded after one use—double-dipping during service is also prohibited.
- 18Hair & Scalp
A scalp massage stimulates blood flow but is contraindicated when the client has:
Answer: B. Active infection or inflammation of the scalp
Scalp massage should not be performed over active infection, open lesions, or significant inflammation — it could spread pathogens and worsen the condition. Refer to a physician if needed.
- 19Salon Business
A salon's monthly cash flow is negative. The owner should:
Answer: C. Analyze causes, cut expenses, or boost revenue urgently
Negative cash flow needs urgent analysis — identify whether causes are temporary (seasonal) or structural (overhead, pricing). Cost reduction and revenue improvement are the levers.
- 20Skin Care
A client has mild acne and asks for extractions. During the facial, the esthetician should perform extractions:
Answer: D. Only on appropriate, non-inflamed lesions
Extractions should target appropriate, non-inflamed lesions (open or closed comedones). Working on inflamed pustules or cysts can worsen inflammation, scarring, and spread bacteria.
- 21Shaving & Barbering
A barber uses 'thinning shears' to:
Answer: A. Remove bulk while preserving overall length
Thinning (texturizing) shears remove some hair to thin without significantly shortening. Used carefully near ends — overuse causes 'see-through' patches.
- 22Skin Care
An esthetician performs an enzyme peel. Enzyme peels generally:
Answer: B. Dissolve keratin proteins to exfoliate gently
Enzymatic exfoliants (papain, bromelain) digest dead skin protein for gentle exfoliation. Suitable for sensitive skin where AHA/BHA might be too aggressive.
- 23Nail Care
Acrylic nail enhancements are formed by mixing two products on the brush. These products are:
Answer: C. A liquid monomer and a polymer powder
Acrylic enhancements form when a liquid monomer and a polymer powder mix on the brush and polymerize at the nail. Proper ratio and application are essential.
- 24Nail Care
An electric nail file (drill) is used to refine acrylic enhancements. The most common safety concern is:
Answer: D. Heat buildup and natural nail thinning damage
Electric files generate heat and can thin or damage the natural nail. Use low RPM, appropriate bit, light pressure, and never apply pressure on the natural nail plate.
- 25Client Consultation
During a service, the cosmetologist notices the client's body language is increasingly tense. The most professional response is to:
Answer: A. Pause and check whether the client is comfortable
Reading body language and checking in is part of good client care. A brief, calm pause to ask 'Are you comfortable?' often resolves an issue before it becomes a complaint.
