Hair Types
Pattern vocabulary plus a seven-axis observation record—not a tool-matching chart.
Describe the working material without prescribing by identity
Record what is observed in the relevant area and state, then define the goal and controlled trial. Apply to Hair Types
- 01 Distribution Observe density and variation by area without inventing a chairside count.
- 02 Fibre Record diameter variation, condition, previous work, and system context.
- 03 Behaviour Note pattern, grouping, shrinkage, movement, and wet or dry state.
- 04 Decision Agree the result and preserve areas, then trial an exact tool responsibly.
Do not inferCurl code, ethnicity, gender, texture word, or photograph cannot determine density, condition, tooth count, steel, edge, size, or technique.
Pattern families can help a client and practitioner talk about visible grouping and direction. They are not biological diagnoses, and they do not determine strand diameter, density, condition, ethnicity, a wet-or-dry method, or a scissor.
Seven observations, kept independent
A pattern label or photograph is only one view. Name the exact area and state, record each axis separately, define the intended task, then review the released result before another irreversible pass.
Observation is not a tool prescription
Strand diameter
Record observable or reliably reported fibre variation in the exact area. “Fine” does not mean low density.
Fibre, not fullnessDensity & distribution
Compare like partings or zones under the same lighting and state. Scalp visibility is a cue, not a hairs-per-area reading.
Area-specificPattern & direction
Describe grouping, direction, and mixed zones in a named state. A 1A–4C label is optional vocabulary only.
May vary by zoneCondition & history
Record observable weathering, breakage, tangling, and relevant chemical, heat, or added-hair history. Do not diagnose.
Refer beyond scopeWorking section & state
Name the area, section size, wet, damp, dry, or resting state, tension, and elevation used by the trained method.
State stays attachedIntended task
Define the line, movement, amount, and location of change—and what the client wants preserved.
Consent defines the taskReleased result
Release tension, comb out, or return to the agreed natural fall. Observe line, movement, spring-back, and visibility before repeating.
Review before repeatMove from a local observation to a released check
-
01
Name the areaKeep zones separate when their behaviour differs.
-
02
Record seven axes“Unknown” is safer than an inferred value.
-
03
Define the taskState the change, location, and what stays untouched.
-
04
Trial the exact modelKeep operator, method, state, and material attached.
-
05
Release & reassessObserve natural fall before deciding on another pass.
Write an observation—not a category verdict
Record “unknown” when the current view cannot support an answer.
Diameter
What variation is observable or reliably reported in this exact area?
RecordDensity
How is hair distributed in like partings or zones under the same view conditions?
RecordPattern
What grouping, direction, and mixed pattern appears in the named state and after release?
RecordCondition & history
What observable weathering, tangling, breakage, or relevant process history belongs in scope?
RecordSection & state
Which area, section size, state, tension, and elevation belong to the trained method?
RecordIntended task
What line, movement, amount, and location is agreed—and what must be preserved?
RecordReleased result
After release, comb-out, or natural fall, what changed? Does the observation justify another pass?
RecordPattern language has one job
Use the 1A–4C entries below as optional pattern vocabulary. Record the viewing state and mixed zones; the same head can show more than one pattern, and the observed pattern can change with length, moisture, styling, product, processing, or damage.
- Keep diameter separate from density.
- Keep pattern separate from condition and history.
- Keep the working section and state attached to every observation.
- Define the intended task and areas to preserve before comparing tools.
- Release the section and record the actual result before repeating.
From observation to a tool trial
A tool comparison begins only after the record is complete. Compare a named model, exact handedness, individual fit, maker-described geometry, care route, and the operator’s trained method on approved practice material. A successful trial stays limited to that model, operator, material, state, and task.
Do not turn a pattern code, hairstyle photograph, demographic label, or service name into an edge, steel, length, tooth-count, or technique recommendation.

5 answers you can open one at a timeWhat can a 1A to 4C label tell me?
It can provide optional vocabulary for an observed pattern family. It does not establish density, strand diameter, condition, ethnicity, wet-or-dry method, edge, tooth count, or technique.
Can I assess hair from a photograph?
A photograph can help discuss visible shape or a desired feature, but crop, light, styling, product, tension, and viewing angle prevent it from diagnosing diameter, density, condition, or cutting response.
Should wavy, curly, or coily hair always be cut dry?
No universal working state follows from a pattern label. Name the exact area and intended finish, follow accountable training and the relevant service method, then record both the working state and released result.
Does a curl label tell me whether to use thinning shears?
No blanket authorisation or prohibition follows from a curl label. Define the task, review the exact tool and method, confirm operator competency and consent, and use a conservative controlled trial before client use.
Does tooth count map to a hair type or removal percentage?
No. Count alone does not establish geometry, spacing, feed, removal, finish, or suitability. Keep the maker, exact model, method, material, working state, and observed released result attached.
