Infection Control: The Most-Tested Topic
Know the difference between sanitation (reduces pathogens), disinfection (kills most pathogens — EPA-registered disinfectants, correct immersion time), and sterilisation (kills all pathogens). Know which implements require full disinfection after each client vs. which are single-use only. Porous items like neck strips are always single-use.
Chemical Services: Relaxers, Perms, and Colour
For relaxers: know sodium hydroxide (lye) vs. guanidine hydroxide (no-lye), the role of pH, and scalp protection protocols. For perms: ammonium thioglycolate breaks disulfide bonds, neutraliser re-forms them. For colour: know the levels 1-10, tone (warm vs. cool), and colour wheel complementary colours for correcting unwanted tones.
Clipper Terminology
Guard 0 = closest clipper cut, Guard 8 = approximately 1 inch. Lower blade number = shorter cut. For fades: blend from skin to longer length using multiple guards. Know taper vs. fade vs. undercut distinctions — they appear on most state exams.
3-Week Study Plan
Week 1: infection control and state laws. Read your state board rule book cover to cover. Week 2: chemical services and anatomy — flashcards for relaxer types and the layers of the scalp. Week 3: timed practice exams — aim for 100 questions per session, review every wrong answer.
