The science
behind the craft
A journal for working barbers and cosmetologists, written for people who touch clients every day. Published free, and not part of the programme’s instruction.
- No. 1 The scalp is not a backdrop Scalp Science for Practitioners Five layers, a working organ, and everything the scalp tells you before the first clipper guard touches skin.
- No. 2 The follicle under load Follicle Mechanics for Practitioners Sustained tension is a mechanical injury pathway with a reversible stage and a scarring stage — and practitioners are positioned to catch the difference.
- No. 3 Developer is not neutral Oxidative Chemistry for Practitioners Volume is a measure of available oxidising power, not a speed setting — and the reaction does not stop at the hair shaft.
- No. 4 The razor line Barrier Science for Practitioners A close shave is a controlled wound to the skin barrier. Blade angle and direction decide whether it heals clean or becomes an ingrown hair.
- No. 5 Sanitation beyond the Board Infection Control for Practitioners Contact time, biofilms, and the real difference between bloodborne and surface pathogens — why the rules exist at all.
- No. 6 The beard interface Facial Hair Science for Practitioners Facial hair grows under different hormonal rules than scalp hair, and the skin beneath a beard has its own dermatologic problems.
- No. 7 The six areas the Board actually inspects Inspection Standards for Practitioners Seven of the fifteen violations the Board cites most often are about disinfection and tool handling. None are about cutting.
- No. 8 What taking on an apprentice obliges you to Trainer Obligations for Practitioners The obligations of hosting an apprentice as the State Board writes them — including the supervision rule that quietly controls the timeline.
