01Infection Control, Sanitation, and Safety
This domain tests how well you can stop the spread of pathogens in a barbershop: classifying microorganisms, choosing sanitation, disinfection, or sterilization for each item, and reacting correctly to a blood exposure. Questions are scenario-heavy, so link every rule to a tool, surface, or client interaction.
326 words, about 2 min02Hair and Scalp Care, Shampooing, and Treatments
This domain tests scalp and hair analysis, shampoo selection and technique, massage, and treatment choices. You must distinguish a serviceable scalp from one that needs medical referral, then match products and water temperature to the analysis.
332 words, about 2 min03Haircutting and Clipper Work
Haircutting items test sectioning, elevation, guide use, and clipper control. The exam expects you to predict the shape a cut will produce from the elevation and guide you choose, then blend that shape safely with clippers.
321 words, about 2 min04Shaving, Beard Design, and Facial Hair Services
This domain covers razor shaving and beard shaping: preparation, razor angle, skin tension, outline placement, and contraindications. The exam favors practical scenarios about comfort, safety, and symmetry.
322 words, about 2 min05Chemical Services: Permanent Waving and Relaxing
Chemical texture items test the science of breaking and re-forming disulfide bonds, product selection, test strands, and neutralization. You must separate waving chemistry from relaxer chemistry and recognize when hair is too damaged for either.
306 words, about 2 min06Haircoloring and Lightening
Haircolor questions test color theory, level, developer choice, gray coverage, and lightening safety. You need to predict the result from the level and tone you select, then apply it without overlapping or overprocessing.
303 words, about 2 min07Anatomy, Physiology, and Histology of Hair and Skin
This domain tests the structures of skin and hair and their functions, plus growth cycles and head anatomy. Questions often ask you to connect a structure to its job rather than simply label a diagram.
293 words, about 1 min08Professional Practices, State Law, and Business Skills
