Hair and scalp analysis before a service

Four findings decide what any chemical service is allowed to be, and the exam expects you to define each one precisely rather than approximately. Texture and density in particular are routinely swapped, and an item will be written to catch exactly that.

TextureThe diameter of one individual strand
DensityHow many strands there are — fine texture and high density coexist happily
PorosityTested by sliding the fingers along a strand toward the scalp
ElasticityWet hair stretches about half its length and recovers
Postpone the chemical serviceA wet strand that stretches and does not recover
When the analysis happensBefore every service, on dry hair
Why dryBuild-up, natural fall and scalp condition are only visible dry
Growth patternsCowlicks and whorls change what a haircut can actually do
Record the findingsThe next service depends on knowing how this hair behaved

Where the point is lost: The scalp half of the analysis is the half that stops services. Abrasions, inflammation or open sores rule out massage and rule out every caustic chemical. The greasy, waxy form of dandruff with inflammation is a referral rather than a salon treatment, tinea capitis is a contagious fungal infection, and head lice found while parting hair means stopping, telling the client privately, and referring. In none of those cases do you name the condition as a diagnosis.

Questions and answers, explained

All 12 questions above, with the correct answer and why it is correct. Everything here is on hair and scalp analysis before a service.

  1. What does hair texture describe?

    • AHow many strands grow in a square inch of scalp
    • BThe diameter of an individual strandCorrect
    • CHow readily the strand absorbs moisture
    • DThe degree of natural wave or curl in the hair

    Why: Texture is the thickness of one strand, classified as fine, medium or coarse. Strands per square inch is density, absorption is porosity, and the wave pattern is a separate characteristic sometimes called wave configuration. The exam swaps these four terms constantly because they are easy to confuse and precisely defined.

  2. Which form of dandruff requires referral to a physician rather than salon treatment?

    • AThe dry, flaking form with loose white scales
    • BAny dandruff a client has had for more than a month
    • CThe greasy, waxy form with inflammationCorrect
    • DDandruff appearing only after a chemical service

    Why: The greasy, waxy, inflamed form involves skin that is actively irritated and is referred, because identifying and treating it is a medical matter. The dry flaking form may be managed in the salon with an appropriate shampoo. Duration alone does not decide it, and flaking after a chemical service points to irritation from the product rather than to a form of dandruff.

  3. A client has very fine strands but a great many of them. How is this described?

    • ACoarse texture with low density
    • BHigh porosity with good elasticity
    • CFine texture with high densityCorrect
    • DMedium texture with average density

    Why: Texture and density are independent, so fine hair can be dense and coarse hair can be sparse. This client is fine in texture and high in density. Porosity and elasticity describe how the strand absorbs and stretches and say nothing about thickness or quantity.

  4. Tinea capitis is what kind of condition?

    • AA non-contagious dryness of the scalp
    • BA bacterial infection treatable with salon products
    • CA contagious fungal infection of the scalpCorrect
    • DA parasitic infestation visible as moving insects

    Why: Tinea capitis is ringworm of the scalp — a contagious fungal infection. The client is not serviced, is referred to a physician, and everything they contacted is disinfected or discarded. It is neither bacterial nor parasitic, and no salon product treats it. Pediculosis is the parasitic infestation it is sometimes confused with.

  5. How is porosity tested?

    • ABy counting the strands within a one-inch parting
    • BBy stretching a wet strand and watching whether it returns
    • CBy applying the color formula to a small hidden section
    • DBy sliding the fingers along a strand toward the scalpCorrect

    Why: Running the fingers from the ends toward the scalp against the cuticle reveals roughness — the more the strand resists and feels raised, the more porous it is. Stretching a wet strand is the elasticity test, counting strands measures density, and applying the formula to a hidden section is a strand test that previews the result.

  6. When must scalp massage be avoided?

    • AWhen the client's hair has been chemically colored
    • BWhen the client's scalp is naturally oily
    • CWhen there are abrasions, inflammation or open soresCorrect
    • DWhen the client has fine or thinning hair

    Why: Massage over broken or inflamed skin worsens the injury and can spread infection, so it is omitted. It is also avoided immediately before a chemical relaxer, since irritated skin plus a hydroxide product is a chemical burn. Colored hair, oily scalps and fine hair all call for adjusted pressure and product rather than omission.

  7. Hair with good elasticity will stretch approximately how far when wet without breaking?

    • AAbout a quarter of its length
    • BIts full length again, or double
    • CAbout half its lengthCorrect
    • DOnly a few millimetres in total

    Why: Wet hair in good condition stretches roughly fifty per cent and returns without breaking; dry hair stretches around twenty per cent. Hair that stretches and stays stretched has poor elasticity and is a reason to postpone a chemical service. Doubling in length would mean the internal structure had already failed.

  8. Why is an acid-balanced conditioner or rinse used after shampooing?

    • ATo raise the pH so the hair can absorb more moisture
    • BTo dissolve any product residue the shampoo left behind
    • CTo close the cuticle that the alkaline shampoo liftedCorrect
    • DTo permanently seal the hair against future damage

    Why: Shampoo is alkaline and raises the cuticle; an acidic product brings the pH back toward the hair's natural 4.5 to 5.5 and lays the scales flat, which produces shine and reduces tangling. Raising pH further is what caused the roughness in the first place, residue removal is a clarifying shampoo's job, and no conditioner offers permanent protection.

  9. A client asks the cosmetologist what a patch of scaly skin on her scalp is. How should this be answered?

    • ABy naming the most likely condition based on its appearance
    • BBy recommending an over-the-counter treatment for it
    • CBy reassuring her that such patches are usually harmless
    • DBy explaining that only a physician can identify itCorrect

    Why: Identifying a skin condition is diagnosis, which is the practice of medicine and outside a cosmetology license. Recommending a treatment for it is the same problem in a different form. Reassuring her that it is probably harmless is a diagnosis too — just one delivered casually — and it may delay care she needs.

  10. Which phase of the hair growth cycle is the active growing phase?

    • ATelogen, the resting phase before shedding
    • BCatagen, the brief transitional phase
    • CAnagenCorrect
    • DAll three phases involve active growth at different rates

    Why: Anagen is the active growth phase and lasts for years, which is why it accounts for the great majority of hairs on a healthy head at any time. Catagen is a short transition and telogen is the resting phase that ends in shedding. Only anagen involves growth, which is what makes shedding patterns diagnostic.

  11. How is the scalp manipulated during a shampoo?

    • AWith the fingernails, to loosen flakes from the scalp
    • BWith the palms pressed flat against the head
    • CBy rubbing the hair lengths against each other
    • DWith the cushions of the fingertips, in a firm circular motionCorrect

    Why: The pads of the fingertips work in small firm circles, which cleanses effectively and stimulates the scalp without scratching it. Fingernails abrade the skin, and broken skin before a chemical service is a burn waiting to happen. Flat palms achieve nothing, and rubbing the lengths together tangles and roughens the cuticle.

  12. A client has patchy hair loss along the front hairline where she wears tight braids. What is the likely cause?

    • AA fungal infection requiring immediate referral
    • BAndrogenic alopecia, which follows a hereditary pattern
    • CTraction alopecia from sustained tension on the folliclesCorrect
    • DTelogen effluvium caused by a systemic illness

    Why: Loss confined to the areas under sustained pulling is the pattern of traction alopecia, and reducing tension is what stops it — caught early it is reversible. Androgenic loss follows a hereditary pattern rather than the placement of a hairstyle, telogen effluvium is diffuse rather than patchy, and a fungal infection would show scaling and inflammation. Persistent or worsening loss is still referred.
