GA Cosmetology common mistakes
GA Cosmetology · Understand the traps and how to avoid them.
On implement-care items, choosing 'wash with soap and water,' 'sanitize,' or 'sterilize' interchangeably - e.g., selecting 'soapy water soak' as the correct handling for a razor nicked with blood, or picking 'sterilize' for a comb used on intact hair.
Everyday speech treats these words as synonyms, and candidates memorize a supply list ('Barbicide, UV cabinet, autoclave') without learning which level of microbial kill each item requires, so the first plausible-sounding option wins.
What to do instead
Build a three-rung ladder and a single decision rule you apply before reading the options: clean (soap and water, removes debris only) → disinfect (EPA-registered hospital-grade, kills most organisms on non-porous implements) → sterilize (kills spores, used where blood/body fluid may be present or as required by rule). Then classify the item: porous or single-use = discard; non-porous and touched a client = clean then disinfect; penetrated skin or contaminated with blood = the higher level your Board rules require.
pH questions: reading the scale backward (calling pH 3 'less acidic than pH 5'), or treating the numbers as evenly spaced (believing pH 4 is only slightly stronger than pH 5 rather than ten times).
The pH scale is logarithmic and most candidates have not used logarithms since high school, so they reason about it as if it were a ruler and extrapolate wrong answers confidently.
What to do instead
Anchor three points cold - 0 = strongest acid, 7 = neutral, 14 = strongest base - and memorize one sentence: each whole step is a tenfold change, so pH 5 is ten times more acidic than pH 6. Drill with pairs (which is more alkaline: 9 or 11? which is stronger: 3 or 4?) until the direction is automatic, then connect to salon products: acids tighten the cuticle, alkalis swell it.
Anatomy items answered by recognising a structure's shape on a diagram but not its job - for example matching 'sebaceous gland' to 'cushions the finger' or 'arrector pili' to 'produces oil,' or naming the epidermis as the layer containing blood vessels and nerves.
Study time went into labelling pictures and re-reading charts, which builds visual recognition but not the function-based reasoning most exam items test.
What to do instead
Convert every structure into a two-line card: 'what it does' + 'what goes wrong if it doesn't.' E.g., sebaceous gland → secretes sebum to lubricate skin and hair → overactive = oily scalp, blocked = comedone; arrector pili → contracts to raise hair → goosebumps. Also fix the layer facts as pairs: epidermis = no blood vessels, dermis = vessels, nerves, glands, follicles.
Developer/lift items: answering from a remembered brand chart ('20 volume lifts two levels') instead of the relationship between volume, peroxide percentage, and lift - and therefore picking '30 volume' where the question is really asking about deposit-only.
Manufacturer charts differ, so memorised numbers conflict across study sources and candidates latch onto whichever chart they saw last rather than the underlying rule.
What to do instead
Learn the conversion that never varies - 10 volume = 3% peroxide, 20 = 6%, 30 = 9%, 40 = 12% - and the principle that lift comes from the amount of peroxide available and the alkalinity of the product. Then add the lift estimate as a secondary layer (10 volume deposits only; each higher volume raises lift), and when an item mentions gray coverage or 'deposit only,' go to the lowest volume that opens the cuticle adequately.
Chemical texture items answered with the steps out of order - placing the neutralizer before the relaxer has been fully rinsed, or assuming a thio relaxer and a sodium hydroxide relaxer are processed and neutralised the same way.
Relaxing and permanent waving both use 'process, rinse, neutralise' language, so the sequences blur together and candidates pick the option that 'sounds like the last thing you do' rather than the chemically correct order.
What to do instead
Write the chemistry as a story you can retell: the relaxer breaks disulfide bonds (lye = no-base/with base, thio = curl-reducing chemistry on different pH), the rinse removes the product and stops the action, and the neutralizer rebuilds the bonds in the new shape. Practise stating the sequence aloud from memory for each product family, and for every practice item underline the word that tells you which family it is.
Nail items: treating a fungal infection, a bacterial infection, or an inflamed nail fold as something a nail technician can treat with product, and confusing a disease (onychomycosis, paronychia) with a disorder (onychorrhexis, leukonychia).
Nail service training focuses heavily on products and appearance, so candidates over-apply 'I can fix that' thinking and pick the answer that keeps the client in the chair.
What to do instead
Memorise the boundary as a one-liner: disease = refer to a physician, disorder = cosmetology may service cosmetically. Build two short lists - red-flag disease signs (pus, swelling, pain, discolored drainage, lifted plate with debris, dark streak under the plate) and non-infectious disorders - and rehearse the script 'I can't service this; here's the referral.' Also fix scope basics: no cutting living tissue, no nipping the nail fold, no treating infection.
Skin items: answering 'skin type' when the item is asking about a 'skin condition' (or vice versa), and selecting an extraction or treatment for pustular, inflamed, or undiagnosed lesions.
Types (dry, oily, combination, normal) and conditions (dehydration, sensitivity, acne, rosacea) are taught in the same unit and described with overlapping words like 'oily' and 'tight,' so candidates answer the label rather than the question stem.
What to do instead
Separate them on paper: type = genetic, stable oil/water balance; condition = changeable and can be triggered. Then learn the contraindication rule - inflamed, pustular, broken, or undiagnosed lesions are not extracted and not treated; refer out. Read each skin stem twice specifically asking 'is this asking what they are, or what is happening right now?'
Business math items: computing markup as if it were margin, or figuring a commission/booth-rental decision without converting the service price and product cost into the same units - producing an answer that is close but wrong.
Both terms are described in plain English in textbooks, so candidates plug numbers into whichever formula they remember and never check the result against a sanity estimate.
What to do instead
Drill the two formulas until they are distinct: markup = (price − cost) ÷ cost; margin/gross profit = (price − cost) ÷ price. Before answering, do a 5-second estimate ('if I double the cost I roughly double the price') and reject any option that is wildly off. For commission items, always write down: service price, product cost, commission %, then net to the stylist and net to the salon as two separate lines.
Salon management items: assigning sanitation duties to the salon owner or the receptionist rather than to the licensee performing the service, and treating the Safety Data Sheet, chemical labelling, and blood-exposure response as optional paperwork.
In the workplace, housekeeping is often delegated, so candidates answer from what they have seen rather than from the rule that each licensee is personally accountable for the client in their chair.
What to do instead
Adopt one default: the person performing the service owns the sanitation of the implements, station, and themselves. Learn the management facts as a short checklist you can recite - SDS kept and accessible for every chemical in the salon, containers labelled, exposure incident = stop, wash, report, follow the written plan - and apply that checklist whenever an item describes a scenario with a spill, splash, or unlabelled bottle.
Georgia law items: answering from general cosmetology knowledge or from a neighbouring state's rules - assuming a licence transfers automatically by reciprocity, or picking an answer about inspection, licence display, or scope that sounds standard but is not what Georgia's Board rules actually say.
Prep material is often national, and the state-specific chapter gets skimmed last, so the candidate's default answer reflects the majority rule rather than Georgia's.
What to do instead
Treat Georgia law as its own subject with its own study block: read the Board's published rules and the licensing statute directly (the Board sits within the Georgia Secretary of State's office), and make a one-page sheet of the items most often tested - who must hold a licence and what each licence authorises, how licensure by endorsement/transfer works, display of licence, sanitation and inspection expectations, and what counts as unlicensed practice. For any state item, ask 'what does Georgia's rule say?' before reading options.
