MT Cosmetology common mistakes
MT Cosmetology · Understand the traps and how to avoid them.
Answering Montana sanitation questions with the generic national rule (for example, saying implements must be disinfected with a 10-minute soak in quats or that all tools must be sterilized) instead of the specific concentration, contact time, and container-labeling rules the Montana Board of Barbers and Cosmetologists actually requires.
Candidates study from national review books that summarize OSHA and CDC guidance, then assume the state exam simply repeats it. Montana-specific numbers (disinfectant dilution, immersion time, wet vs. dry storage, how long to keep records) do not always match the textbook default, so the 'obvious' answer is wrong.
What to do instead
Build a one-page Montana rule sheet directly from the current Administrative Rules of Montana title governing barbers and cosmetologists and the Board's sanitation rule. For each item write the exact number: disinfectant type, concentration, immersion time, frequency of changing solution, and labeling requirement. Quiz yourself only from that sheet in the final week.
Confusing disinfection with sterilization and choosing 'sterilize' as the correct answer for routine salon implements such as combs, shears, and clipper blades.
The words sound interchangeable in everyday speech, and candidates overcorrect after being warned that 'just washing' is wrong. Sterilization (autoclave, dry heat) is not the legal or practical standard for most salon tools, so picking it signals a misunderstanding of the infection-control hierarchy.
What to do instead
Memorize the ladder: cleaning removes visible debris, disinfection kills most pathogens on nonporous surfaces, sterilization destroys all microbial life including spores. Then attach each salon item to its required level: porous or single-use items are discarded, nonporous implements are cleaned then disinfected, and sterilization applies only where the rule explicitly names it. Practice with a list of 20 real implements and assign the level to each.
Treating the hair's layers and the skin's layers as one blended fact set, so the candidate says the cortex is the outer protective layer or that the dermis is the outermost skin layer.
Histology is taught early and then only revisited in coloring and skin-care chapters, so the terms get shuffled under exam pressure. Questions that combine structure with function (where pigment lives, where curl pattern is determined, which layer sheds) punish rote memorization without a mental diagram.
What to do instead
Draw the hair shaft and the skin cross-section from memory daily until the order is automatic: cuticle, cortex, medulla for hair; epidermis, dermis, subcutaneous for skin. For each layer write one function and one service implication (cuticle must be raised for color to penetrate; the dermis holds blood vessels and nerves, so a facial massage works on the structures above it).
Applying a relaxer or thioglycolate permanent wave using the same timing and strength logic as hair color, or assuming a virgin application and a retouch follow the same procedure.
Both are 'chemical services with a processing time,' so candidates collapse them into one workflow. They forget that relaxers break disulfide bonds and are governed by base and no-base placement, strand testing, and scalp protection, and that retouches must not overlap previously relaxed hair.
What to do instead
Separate the two systems explicitly in notes: color changes pigment inside the cortex, texture services change bonds in the cortex. For relaxers, drill the sequence (client consultation and strand test, scalp protection, application pattern for virgin vs. retouch, smoothing, rinsing, neutralizing shampoo, conditioning) and the rule that the product touches new growth only. Practice identifying which step is skipped in a short scenario.
Diagnosing hair and scalp conditions as treatable when they fall outside the cosmetologist's scope, and recommending a salon service for what is actually a contraindication.
Candidates want to be helpful and see 'recommend a conditioning treatment' as the safe, service-oriented answer. They miss that redness, pus, ringworm-like patches, open sores, or sudden hair loss require referral, and that performing a service can spread infection or worsen the condition.
What to do instead
Learn a short 'refer, do not treat' list with visual descriptions: tinea, impetigo, pediculosis, folliculitis with pus, abnormal shedding. For each, state the service implication in one sentence (no service, refer to a physician, disinfect implements and linens). On practice questions, first ask 'is this within my license?' before asking 'what service helps?'
Using the wrong elevation, guide, or distribution and then mislabeling the resulting shape, for example calling a uniformly layered cut a graduated bob or confusing a stationary guide with a traveling guide.
Cutting terminology is learned through physical practice, and reading a text description strips away the visual feedback. Candidates memorize definitions without linking each term to the angle and the resulting silhouette, so scenario questions that describe a technique trip them up.
What to do instead
Build a table with three columns: technique (elevation, guide, distribution), resulting shape and weight line, and a real example. Add a sketch of the silhouette for each row. When reviewing a missed question, identify which of the three columns you got wrong rather than re-reading the whole chapter.
Skipping the client consultation and patch test as 'paperwork' and answering service questions as if the service begins at the shampoo bowl.
Practical exam habits carry over: candidates rehearse the hands-on steps and treat consultation, patch testing, and client-record notes as optional extras. Exam questions that place a contraindication or an allergy in the scenario expect the candidate to catch it before any product is applied.
What to do instead
Treat consultation as step one of every service. Memorize what must be asked and recorded: allergies, medications, prior chemical services, scalp or skin conditions, and the patch-test interval required before aniline-derivative color. Rehearse a 60-second consultation script aloud so the order becomes automatic in scenario questions.
Mixing up nail anatomy and disease versus disorder terminology, such as calling a fungal infection a disorder or identifying the matrix as the visible nail plate.
Nail care chapters pack many similar-sounding terms (lunula, cuticle, eponychium, hyponychium, matrix, bed) into a short section, and candidates skim because the practical manicure feels easy. Exam questions test exactly those distinctions plus the boundary between conditions a manicurist may work over and those requiring referral.
What to do instead
Label a blank nail diagram from memory until every structure is placed correctly, then add a second column for what each structure does and what can go wrong there. Make a two-column list of disorders (structural or systemic, may be served with care) versus diseases (infectious, refer out) with one example each, and review the list before every practice test.
Treating skin care and facial services as a single generic routine, so the candidate cannot order the steps of a basic facial or explain why a given massage movement or product is used for a given skin type.
Facials are often studied last and compressed into a list of steps without the reasoning behind them. Candidates then confuse cleansing and exfoliation order, or recommend a stimulating treatment for a client whose skin type calls for calming care.
What to do instead
Write the facial as a numbered sequence with the purpose beside each step: consultation and skin analysis, cleansing, exfoliation, massage, mask, moisturizer and sun protection. For each skin type (dry, oily, sensitive, combination) note which product or movement changes and why. Practice ordering shuffled step cards until the sequence and rationale are both automatic.
Answering styling and finishing questions by tool name rather than by the effect on the hair, for example assuming a blow-dryer with a diffuser and a round brush create the same result, or that thermal protection is only needed for flat irons.
Styling is learned by doing, and candidates remember the tool they used in lab rather than the principle (heat and tension create shape; moisture and cooling set it). Questions that describe a desired outcome rather than a named tool expose the gap.
What to do instead
Reframe notes around outcomes: volume at the base, smoothness along the shaft, bend versus curl, hold versus flexibility. Under each outcome list the tools and techniques that achieve it and the heat or product needed. Add a short section on thermal protection and temperature ranges for fine, medium, and coarse hair, and review it with the finishing chapter.
