IA Cosmetology study guide
IA Cosmetology · Work through your exam, one topic at a time.
The Iowa Cosmetology Arts and Sciences licensure pathway is administered through the Iowa Department of Inspections, Appeals, & Licensing (DIAL), which lists Barbering & Cosmetology among its licensed programs. DIAL's public pages show separate licensure routes for barber/cosmetology, esthetician, nail technologist, electrologist, instructor, establishment, one-year permit, and renewal/reactivation, plus a blow-dry stylist pathway and a natural hair braiding registry. This page is an independent study resource for candidates preparing for Iowa cosmetology arts and sciences licensure; it is not affiliated with DIAL or any Iowa board. The study domains here group content into general practice, hair care and styling, esthetics and skin care, and nail technology, so you can build a balanced review rather than drilling one service area. The IA Cosmetology study guide has 4 sections and about 1,223 words.
01Cosmetology Arts and Sciences: Foundations, Safety, and Professional Practice
This domain tests the foundational science and safety that underpin every service: infection control, anatomy and physiology, chemistry, electricity, and legal/regulatory practice. Expect questions that ask you to choose the safest, most defensible action rather than the fastest one.
