MS Barber common mistakes
MS Barber · Understand the traps and how to avoid them.
Sprays clippers and shears with disinfectant, wipes them dry, and reuses them on the next client within a minute.
Memorizes 'disinfect tools between clients' as a motion rather than a timed procedure; exam items test label contact time and EPA registration.
What to do instead
Answer with the product label: EPA-registered hospital disinfectant, tools fully immersed or kept wet for the full contact time (often 10 minutes), or rotate a second set while the first soaks.
Reuses one neck strip for several clients, or fastens the cape so it touches the client's neck.
Treats the neck strip as comfort padding instead of a single-use barrier; rushed turnover between clients.
What to do instead
Use a fresh neck strip for every client, fasten the cape so it never contacts skin, and discard the strip in front of the client.
Picks up clippers or shears and starts cutting the top or side without first cutting a guideline at the nape or perimeter.
Time pressure and copying unstructured shop habits; exam scenarios test the order of cutting steps.
What to do instead
State and follow a sequence: section the hair, establish the guideline at the nape or perimeter, cut to the guideline, then cross-check both sides before detailing.
Shaves with the razor held nearly flat against the skin and makes the first pass against the grain.
Equates a closer shave with a better shave and has not practiced angle or grain mapping.
What to do instead
Hold the razor at about a 30-degree angle, keep skin taut, make the first pass with the grain, and re-lather before any against-grain pass.
Accepts the client's statement 'I've been colored before' and proceeds without a patch test or strand test.
Schedule pressure and client reassurance override the chemical-service protocol.
What to do instead
Require a 24-48 hour patch test before first-time color and a strand test before lighteners or relaxers; document results and reschedule if the client refuses.
Rinses a relaxer and shampoos once, then assumes processing has stopped.
Confuses rinsing with neutralizing and does not check product pH.
What to do instead
Use neutralizing shampoo, shampoo until suds stay white or the indicator shows acid pH, then apply conditioner; explain the pH shift that stops processing.
Performs a scalp massage or chemical service on an irritated or scabbed scalp without first doing a scalp analysis.
Skips analysis to save time or fears losing the service.
What to do instead
Perform scalp and hair analysis first; identify contraindications such as abrasions, ringworm, or recent chemical burn, then decline or refer and document the decision.
Confuses the individual barber license renewal date with the shop license or establishment permit and answers using the other.
Both documents are called 'license' and study material often lumps them together.
What to do instead
Build a two-column table: individual license (renewal, continuing education, display) versus shop/establishment permit (inspection, owner, posting), and memorize which agency issues each.
Sets service prices by matching the shop down the street without calculating cost per service.
Business math feels optional, and exam items on markup and cost are treated as guesswork.
What to do instead
Compute cost per service (product plus time plus overhead), apply the markup, and practice one retail markup calculation before exam day.
Mixes up anagen and telogen, or says hair grows from the medulla.
Memorized follicle labels without connecting each structure to its function or growth sequence.
What to do instead
Draw and label the follicle: bulb and matrix produce hair, medulla/cortex/cuticle form layers, and anagen is growth, catagen transition, telogen rest and shedding.
