Cosmetology State Board Study Guide
A practical map of the concepts most written cosmetology exams draw from. Use your state’s current outline to set the final weight and order.
Start with the rules that touch every service
Infection control, consultation, analysis, contraindications, and electrical or chemical safety appear across hair, skin, and nail scenarios. Build that foundation before drilling small technical facts.

Infection Control
Practice cleaning, disinfection, blood-exposure procedures, pathogens, and safe salon habits.
Practice this topic →Anatomy & Physiology
Review the body systems, tissues, muscles, skin, hair, and nail structures relevant to cosmetology services.
Practice this topic →Haircutting
Test angles, elevation, guidelines, sectioning, tools, and safe haircutting decisions.
Practice this topic →Hair Color
Review color theory, developers, lightening, preliminary tests, application, and corrective color.
Practice this topic →Chemical Services
Prepare for permanent waving, chemical relaxing, bond changes, and chemical-service safety.
Practice this topic →Skin Care
Practice skin analysis, facials, hair removal, makeup, contraindications, and basic product knowledge.
Practice this topic →Nail Care
Study natural nail anatomy, disorders, manicure and pedicure procedures, and enhancements.
Practice this topic →Sanitation
Focus on the sanitation and infection-control questions that protect clients and salon professionals.
Practice this topic →Infection control and salon safety
Know the difference between cleaning, disinfecting, and sterilizing; how to follow a disinfectant label; how to handle single-use items; and what to do during blood exposure. Learn storage and laundry rules, personal protective equipment, and when a service must stop.
Hair and scalp science
Review the cuticle, cortex, medulla, follicle, growth cycle, texture, density, porosity, and elasticity. Recognize conditions that affect a service and signs that require referral rather than a cosmetic treatment.
Haircutting, styling, color, and texture
Connect tools and techniques to outcomes: elevation, overdirection, guidelines, thermal safety, color neutralization, developer action, preliminary tests, permanent waving, and chemical relaxing.
Skin and nail care
Study basic skin and nail anatomy, analysis, contraindications, facials, hair removal, manicure and pedicure procedures, and enhancement safety. Remember that cosmetologists recognize and refer suspected disease; they do not diagnose it.
Professional practice
Consultation, recordkeeping, informed service decisions, communication, and safe workstation habits support both exam answers and real clients. Add your state’s laws and prohibited practices from the official source.
