Infection Control & Safety
Protecting clients and yourself from the spread of infection is the single most important professional responsibility in cosmetology. This chapter covers the levels of decontamination, the disinfectants used in salons, common pathogens, and the correct response to an exposure incident. These principles are grounded in standard curriculum and public-health science and apply the same way everywhere.
Hair Care & Cutting
Hair services are the core of most salon work, and sound cutting and care begin with understanding the structure and growth of hair. This chapter covers the layers of the hair, the hair growth cycle, and the fundamental cutting concepts of elevation, angle, and line that create shape.
Chemical Services (Color, Perms, Relaxers)
Color, perms, and relaxers permanently change the hair through chemistry, so they carry both the greatest creative power and the greatest risk. This chapter covers the pH scale as it applies to hair, how oxidative haircolor works, the contrasting chemistry of thio perms and hydroxide relaxers, and the essential safety tests you must perform first.
Skin Care & Facials
Healthy skin care starts with knowing the skin's structure and being able to recognize common conditions. This chapter covers the layers of the skin, frequently seen skin disorders, and the logic of a basic facial.
Nail Care
Manicuring and pedicuring require knowledge of nail anatomy, the ability to tell a serviceable disorder from a condition that must be referred out, and strict sanitation. This chapter covers all three.
Anatomy, Physiology & Trichology
A working knowledge of the bones, muscles, and nerves of the head, face, and neck helps a cosmetologist give safe, effective massage and understand facial shape, while trichology grounds hair and scalp analysis. This chapter introduces those fundamentals.
Cosmetology Chemistry & Electricity
The products and machines used in the salon are applied chemistry and physics. This chapter covers the basics of matter and mixtures, the pH scale, and the electrical currents used safely in salon treatments.
Salon Ecology & Professional Practices
A successful cosmetologist maintains a clean, safe environment, handles chemicals responsibly, and treats clients with honesty and professionalism. This chapter covers salon ecology, chemical safety documentation, and professional ethics.
Hawaii Laws, Rules & Licensing
This chapter covers the Hawaii-specific legal framework that supplements your national cosmetology theory. It focuses on who regulates the profession in Hawaii, the kinds of licenses issued, and the everyday rules every licensee must follow to keep a license in good standing.
Hawaii Health & Safety Rules
The Hawaii Board of Barbering and Cosmetology enforces sanitation and infection-control standards to protect the public. These rules apply the same universal principles you learned nationally, framed as Hawaii's enforceable requirements for implements, single-use items, blood exposure, and the work station.
