MD Cosmetology common mistakes
MD Cosmetology · Understand the traps and how to avoid them.
Answering legal questions using general industry habit or what a neighboring state allows instead of the specific Maryland rule - for example assuming that because a tool is disinfected a certain way in a salon's house policy, that satisfies Maryland's requirement.
Candidates study from national textbook editions or on-the-job training that reflects generic practice, so they never isolate the Maryland-specific numbers (implements, timing, licensing categories, inspection authority) that the exam actually tests.
What to do instead
Build a one-page 'Maryland numbers sheet' from the statute and regulations - license types and renewal cycles, sanitation requirements, prohibited practices, and the Board's authority - and drill it separately from general theory. For every legal item, write the exact citation source next to it so you can tell state-specific facts from general knowledge.
Confusing the roles of disinfection, sanitization, and sterilization - for instance selecting 'sterilize' for tools that only require cleaning and disinfection, or treating a disinfectant as effective against bacterial spores.
The three terms are used loosely in everyday salon speech, and candidates memorize definitions without attaching each term to a specific tool category and a specific level of microbial kill.
What to do instead
Learn a three-tier map: cleaning removes visible debris; disinfection kills most pathogenic organisms on nonporous implements; sterilization destroys all microbial life including spores. Then attach examples to each tier (combs and clips, nippers and reusable blades, porous items that cannot be disinfected) and practice sorting tools into tiers until it is automatic.
Getting the hair color and chemical service math wrong - miscalculating developer volume to lifting ability, misapplying the law of color when neutralizing unwanted tone, or choosing the wrong relaxer strength for a client's hair history.
Candidates memorize color wheel relationships but do not practice applying them to word problems, and they underweight the client-consultation details (previous chemical services, porosity, elasticity) that change the correct answer.
What to do instead
Work timed calculation drills: given a starting level, target level, and developer volume, state the lift and the tone correction. Practice neutralization pairs in both directions. For relaxers, build a decision checklist (curl pattern, previous relaxer, porosity, scalp condition) and answer scenario questions by running the checklist rather than by feel.
Treating skin analysis as a single-step 'what type is this' question and skipping the contraindication check - recommending a treatment or product for a client with visible irritation, recent waxing, or a medical condition.
Esthetics training emphasizes skin typing and product selection, so candidates default to the type-and-treat answer and forget that the safest correct option in a scenario is often to refer out or postpone.
What to do instead
For every esthetics scenario, force three passes before choosing: identify skin type and condition, scan for contraindications and medications, then select the treatment. Practice questions where the correct answer is 'do not perform; refer to a physician' so the reflex is trained.
Skipping nail disease and disorder identification in favor of nail art and service steps, then misclassifying a condition as something a manicurist may treat.
Nail technology study time is often spent on technique and design, and the boundary between what a licensed manicurist may service versus what must be referred is easy to blur.
What to do instead
Create a two-column comparison of common nail and skin conditions (fungal infection, paronychia, onycholysis, pseudomonas, warts, bruised nail) with 'serviceable with precautions' versus 'refer to physician.' Review it weekly and answer every nail scenario by naming the condition first, then the action.
Memorizing infection-control facts without connecting them to client safety and transmission routes, so questions phrased as scenarios (a cut, a spill, a dropped implement) are answered with the wrong procedural step.
Facts are learned as isolated vocabulary rather than as a sequence of actions, and candidates have not practiced the order of steps for blood exposure, spill cleanup, or hand-washing.
What to do instead
Learn infection control as ordered procedures: hand hygiene sequence, blood exposure response, spill cleanup, implement reprocessing from dirty to clean to disinfected to stored. Rehearse each as a numbered list and answer scenario questions by walking the list rather than recalling a single fact.
Misreading negative and exception wording - choosing an option that is true but does not answer 'which is NOT' or 'EXCEPT,' or picking the first true-sounding statement instead of the best answer.
Under time pressure candidates skim the stem, and exam items are deliberately written with several plausible-but-incomplete options.
What to do instead
Adopt a fixed reading routine: underline the qualifier (NOT, EXCEPT, FIRST, BEST, MOST), restate the question in your own words, predict the answer before looking at options, then eliminate. Practice with sets of negatively worded items until the habit is automatic.
Overlooking safety and hazard controls in the physical workspace - ventilation, chemical storage and labeling, electrical safety near water, and ergonomic positioning - and answering only about the service itself.
Candidates focus on the client-facing procedure and treat the environment as background, so questions about product storage, SDS access, or equipment grounding feel unfamiliar.
What to do instead
Study the salon as a system: ventilation and air quality, chemical labeling and SDS availability, electrical safety and cord management, ergonomics and body mechanics, and emergency procedures. For each, know the hazard, the control, and the responsible behavior, and link each to a real station setup.
Answering licensing and scope-of-practice questions by assuming all licensees may perform all services, or that a salon may operate while a license is pending.
Scope of practice and licensing mechanics are abstract compared with hands-on skills, so they get the least study time, and candidates substitute intuition about what 'should' be allowed.
What to do instead
Map each Maryland license category to the services it authorizes and the supervision or facility requirements attached. Memorize the rules on license display, expiration and renewal, and what constitutes unlicensed practice, then test yourself with scenario items about who may perform what and under what conditions.
Managing exam time poorly - lingering on difficult calculation or law items and then rushing the final third, leaving scenario questions unread or changing correct answers on a last-minute review.
Calculation and legal items invite over-thinking, and candidates have not practiced under the actual time limit, so pacing is untested until exam day.
What to do instead
Take full-length timed practice sets and set a per-question budget. Flag and move past any item exceeding the budget, return only after completing the section, and change an answer only when you can name the specific reason the first choice was wrong.
