OH Cosmetology study guide
OH Cosmetology · Work through your exam, one topic at a time.
The Ohio Cosmetology Licensing Examination is the theory assessment used in Ohio's licensure pathway for individuals who want to practice cosmetology and related services, in a system regulated by the Ohio State Cosmetology and Barber Board. The Board describes its mission as protecting and supporting the public through regulation and education while protecting the integrity of the cosmetology and barbering industries, and it ensures that businesses and individuals offering these services comply with licensing requirements and with the infection control and safety standards the Board establishes. The OH Cosmetology study guide has 5 sections and about 1,955 words.
01Scientific Concepts: Infection Control, Anatomy and Physiology, Chemistry
