OR Cosmetology study guide

OR Cosmetology · Work through your exam, one topic at a time.

The Oregon Board of Cosmetology sits within the Health Licensing Office (HLO), part of the Oregon Health Authority's Public Health Division. HLO is a central licensing and regulatory office overseeing multiple health and related professions, and it describes its mission as protecting the health, safety and rights of Oregon consumers by ensuring only qualified applicants are authorized to practice. For cosmetology candidates, that means HLO reviews and approves applicant qualifications, conducts examinations, inspects licensed facilities and independent contractors, responds to and investigates consumer complaints, and disciplines licensees found in violation of state requirements. The Board of Cosmetology is one of the 19 boards, councils and programs HLO works with, and it maintains its own rules and qualifications plus advisory and examination-related committees. The licensing examination is administered as an in-office examination at the HLO office in Salem. Testing hours are Monday through Friday 9 a.m. Topics on this exam: Cosmetology theory and practice (official domain list not published in source). The OR Cosmetology study guide has 1 section and about 401 words.

Cosmetology Theory and Practice (Oregon)

This domain tests the theory and applied practice on Oregon’s cosmetology licensing exam: infection control, anatomy and physiology, product chemistry, hair/skin/nail services, and Oregon Board of Cosmetology rules. Items are scenario-based, so apply the rule to the client in front of you. Cleaning removes visible debris; disinfection kills most pathogens on nonporous surfaces; sterilization destroys all microorganisms. In Oregon salons, reusable nonporous implements (combs, shears, metal clips, reusable drill bits) must be cleaned, rinsed, dried, then fully immersed in an EPA-registered hospital disinfectant at the label’s dilution and contact time.
