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.
Iowa Cosmetology Laws, Rules & Licensing
The state portion of the Iowa cosmetology exam begins with how the profession is regulated in Iowa and how a person becomes and stays licensed. This chapter covers the Iowa Board of Cosmetology Arts and Sciences and its authority, the license types the state issues, scope of practice, and the renewal, display, and prohibited-practice rules that keep a license in good standing. These state rules sit on top of the shared national theory and are the most heavily weighted part of the supplement.
Iowa Cosmetology Health & Safety Rules
Protecting clients from infection is the heart of state cosmetology safety rules. This chapter covers how Iowa expects practitioners to clean and disinfect tools, handle single-use items, and respond to blood exposure, plus the general sanitation standards the board enforces during establishment inspections. These are state-specific overlays on the national infection-control theory.
