The Kentucky Cosmetology Licensure Examination is the multiple-choice theory test that the Kentucky Board of Cosmetology requires before a candidate can be licensed to practice cosmetology, esthetics, or nail technology in the state. It is written for students completing a board-approved training program and for out-of-state or lapsed licensees who need to demonstrate current knowledge. The KY Cosmetology study guide has 7 sections and about 2,193 words.
01Scientific Concepts
This domain tests the anatomy, physiology, chemistry, and microbiology that underlie every service. Expect questions that connect structure to behavior: why alkaline products swell hair, where melanin sits, how the nail plate grows, and which microbes survive disinfectants.
359 words, about 2 min02Hair Care and Haircutting
This domain tests the service sequence from draping through finishing: shampooing and conditioning, haircutting foundations, and styling. Questions often ask you to choose a product or technique for a stated hair condition, or to spot a sanitation or tension error.
340 words, about 2 min03Chemical Services
This domain tests haircolor, permanent waving, chemical relaxing, and keratin smoothing. Expect safety sequencing, patch and strand tests, product chemistry, and the difference between rebuilding disulfide bonds and breaking them.
315 words, about 2 min04Skin Care and Makeup
This domain tests facials, skin analysis, hair removal, and makeup application. The exam links skin type and condition to product choice, and tests contraindications and sanitation as much as technique.
