LA Barber common mistakes
LA Barber · Understand the traps and how to avoid them.
Treating disinfection as a quick wipe-down: spraying a clipper blade or shear with disinfectant and returning it to the drawer while still wet, or skipping the wash step before immersion.
Candidates memorize the word 'disinfect' but not the sequence, and they underestimate contact time. They also assume visibly clean tools need no intermediate cleaning, so they never build the wash-rinse-disinfect-dry order into their mental checklist.
What to do instead
Memorize the fixed order as a chant: clean with soap and water, rinse, fully immerse in an EPA-registered hospital-grade disinfectant at the label dilution, wait the full label contact time (commonly 10 minutes), then dry and store in a clean closed container. Practice saying the order aloud for each tool type: clippers, shears, combs, razors, and brushes.
Confusing the levels of control: calling a hospital-grade tuberculocidal disinfectant a 'sterilant', or claiming that soaking combs in disinfectant sterilizes them.
The terms sanitize, disinfect, and sterilize appear together in study material and sound interchangeable, and candidates latch onto the strongest-sounding word because it feels safer.
What to do instead
Build a three-row table: sanitizing reduces bacteria on surfaces; disinfection destroys most pathogenic organisms but not necessarily bacterial spores; sterilization destroys all microbial life including spores and is done with an autoclave or dry heat sterilizer. Attach one example to each row (e.g., disinfectant jar for combs, autoclave for porous items) so the words stop blending.
Skipping or faking the patch test and strand test before an aniline derivative tint or a relaxer, or performing them only when the client asks.
In a busy shop the tests feel like a formality, and candidates fear losing the client if they add a 24-48 hour wait. They also mix up which product requires which test.
What to do instead
Fix the rule in memory: a patch test for allergy is required before any aniline derivative hair color, and it must be done 24-48 hours before the service, with results recorded. A strand test is a separate predictive test for processing time and color result, done the same day. Write both into a mock client consultation script and rehearse it, including the refusal conversation.
Applying relaxer to the scalp and hairline as if it were shampoo, then smoothing it through already-relaxed or previously processed hair.
Candidates visualize relaxer application like lathering and forget that the chemical is meant to sit off the scalp and that overlapping onto previously relaxed hair causes breakage. They also lose track of the clock during application.
What to do instead
Rehearse the base-and-apply sequence: protect the scalp with a base, apply to the new growth only, keep product off the scalp and skin, and never overlap onto previously relaxed hair. Set a timer at the start of application and note the manufacturer's maximum processing time. For no-lye versus lye, learn which requires the mid-protein/acid-balanced step and why.
Wrapping a wet haircut or performing a blow-dry without ever checking the client's scalp for redness, lesions, or contagion, and continuing a service on an inflamed scalp.
Candidates treat the consultation as small talk and are embarrassed to inspect the scalp closely. They also assume that if the client does not complain, nothing is wrong.
What to do instead
Make a scalp and skin inspection a scripted, non-negotiable step: part the hair in four sections, look at the scalp under good light, and note redness, flakes, lesions, or parasites. Practice a neutral sentence for referral: 'I see something on your scalp that I'm not trained to treat; you'll want a physician to look at it before we continue.' Contagious conditions mean no service.
Using the razor at too steep an angle and shaving against the grain on the first pass, then treating razor burn as an unavoidable cost of the shave.
The goal is a close shave, and candidates equate closeness with pressure and against-the-grain strokes. They also skip skin tension and lubrication because the mannequin does not complain.
What to do instead
Set the angle in muscle memory: the razor is held at roughly a 30-degree angle, with the skin held taut and the stroke moving with light pressure. First pass goes with the grain; against-the-grain strokes are reserved for a second pass and only when the skin tolerates it. Always apply a lubricant, and finish with a cool towel and an aftershave product appropriate for the skin.
Answering anatomy questions with function words when the question asks for structure, or mixing up the three growth phases and what happens in each.
Study material presents structure and function side by side, and candidates memorize the names of phases without attaching a distinct event to each, so the phases become interchangeable labels.
What to do instead
Anchor each phase to one image and one fact: anagen is the active growth phase and the longest; catagen is the short transition when growth stops and the follicle shrinks; telogen is the resting phase before shedding. For structure, draw and label a hair follicle once from memory: bulb, papilla, sebaceous gland, arrector pili, medulla, cortex, cuticle. Then answer ten questions where you must name the structure, not describe what it does.
Using a comb or brush through wet, fragile hair starting at the scalp, and detangling with short ripping strokes.
Candidates imitate how they brush their own hair and do not connect mechanical damage to cuticle loss. Wet hair feels pliable, so it seems safer than it is.
What to do instead
Practice the detangling sequence on a mannequin: apply conditioner or detangler, start at the ends, and work upward in small sections with a wide-tooth comb while holding the hair above the comb to remove tension. Learn the scalp massage and shampoo manipulations as separate, deliberate movements rather than scrubbing, and keep water temperature moderate.
Answering Louisiana law questions from general barbering knowledge or from another state's rules, especially on licensing, sanitation inspections, and shop requirements.
Candidates study the technical domains heavily and treat the law domain as common sense, not realizing that specific numbers, titles, and procedures are board-specific and change.
What to do instead
Study the current Louisiana barbering statute and board rules as a separate, dated document, and build a one-page fact sheet of exact figures: licensing and renewal cycles, continuing education hours, shop license and inspection requirements, display-of-license rules, and penalties. Verify every number against the board's official publication rather than a prep summary, and flag anything you cannot confirm.
Handling a client safety situation, such as a cut during a shave or a chemical in the eye, by improvising instead of following a known sequence.
Candidates study ethics as abstract virtues and never rehearse the concrete emergency steps, so under pressure they freeze or act in the wrong order.
What to do instead
Memorize two short protocols. For a nick: stop, apply clean gauze with light pressure, discard contaminated materials, and disinfect the implement. For chemical in the eye: flush with cool water for at least 15 minutes, remove contact lenses if present, and refer for medical attention. Also memorize the professional boundaries: no diagnosis, no treatment claims, client confidentiality, and disclosure of product risks before service.
