Distinguish the living follicle from the keratinized shaft.
Cuticle, cortex and an optional medulla have different structural roles.

Porosity, elasticity and past treatment affect product behavior.
A cosmetic observation does not establish a medical diagnosis.
Haircut planning, geometry, sectioning and cross-checking
Agree design, realistic length and maintenance before cutting.
A guide, elevation, overdirection and tension are different controls.
Assess curl return and natural growth rather than force uniform tension.

Tool technique and clearance are system-specific.
A designated single-use blade remains single use.
Cleansing, conditioning, drying and temporary styling
Fit cleansing and conditioning to scalp and lengths separately.
Foam amount does not independently establish cleaning performance.

Product instructions control the actual formula and process.
Underlying pigment and fibre history affect tonal results.
Hydroxide and thioglycolate pathways are not interchangeable.
A strand check and a skin allergy check have different purposes.
