Eyelash Technician study guide
Eyelash Technician · Work through your exam, one topic at a time.
The Eyelash Technician Certification Exam is a knowledge assessment for people who apply, maintain, and remove semi-permanent individual eyelash extensions, and for students preparing to enter that work. It tests the foundation a client-facing lash professional is expected to hold: eye and lash anatomy, sanitation and infection control, consultation and contraindications, product and adhesive chemistry, application technique, removal and aftercare, professional practice, and occupational health and safety. The Eyelash Technician study guide has 8 sections and about 3,485 words.
01Anatomy and Physiology of the Eye and Eyelashes
The anatomy and physiology domain checks whether you understand the structures you work around and the growth cycle that explains what you see at every appointment. Expect questions on lash follicle biology, eyelid layers and glands, tear film, and how each fact changes an application or aftercare decision.
525 words, about 3 min02Sanitation, Disinfection, and Infection Control
This domain tests whether you can defend every item and surface in your treatment area with a defined process. Questions focus on the difference between cleaning, disinfection and sterilization, correct product selection, contact time, single-use rules, and blood exposure response.
431 words, about 2 min03Client Consultation, Contraindications, and Patch Testing
This domain tests the conversation before the tweezers come out: how you gather history, decide whether a client can be treated, document consent, and run a patch test that actually means something. Exam items often present a client scenario and ask whether to proceed, modify the service or refer.
421 words, about 2 min04Product Knowledge and Adhesive Chemistry
This domain tests whether you understand why an adhesive behaves the way it does, so you can diagnose cure problems instead of guessing. Expect questions on cyanoacrylate chemistry, monomer types, viscosity, cure speed, environmental control, shelf life and remover compatibility.
423 words, about 2 min05Lash Extension Application Techniques
This domain tests the mechanics of a safe, well-built set: isolation, placement, weight, mapping, curl selection and the difference between classic and volume work. Exam items often ask you to judge whether a proposed set is appropriate for a given natural lash.
445 words, about 2 min06Lash Removal, Aftercare, and Maintenance
This domain tests what happens after the set is built: how to remove extensions safely, what to tell clients in the first 48 hours, and how to keep a set looking good between fills. Exam items frequently test aftercare myths and the correct response to adhesive in the eye.
416 words, about 2 min07Professional Practices, Ethics, and Business Operations
This domain tests the business and ethical frame around the service: scope of practice, records, consent, insurance, pricing and honest marketing. Items often present a client request that pushes past your training and ask for the correct professional response.
406 words, about 2 min08Occupational Health and Safety
This domain tests the risks you carry as a technician rather than the risks to the client: chemical exposure, ergonomics, waste handling and emergency response. Items often describe a workplace incident and ask for the safest immediate action.
