✍️ Sample LASH CERTIFICATION Questions & Answers
1. What is a recommended best practice for reducing allergic reaction risk with new, first-time clients?
A patch test 24-48 hours before the first full service is a widely recommended best practice for identifying sensitivity before a full application.
2. What defines a 'volume' lash set as opposed to a classic set?
Volume sets apply multiple ultra-fine extensions fanned onto a single isolated natural lash, rather than one extension per lash.
3. Which mapping style places the longest lengths progressively toward the outer corner for an elongated, lifted look?
Cat eye mapping increases length toward the outer corner, creating a lifted, elongated effect.
4. What is the single biggest cause of poor lash extension retention on the client's side?
Oil-based products (skincare, makeup, cleansers) break down cyanoacrylate bonds and are the most common client-side retention killer.
5. What is a 'stickie' in lash extension terminology?
A stickie occurs when an extension is bonded across two or more natural lashes instead of one isolated lash, causing uneven shedding and potential lash damage.
6. A client reports redness and swelling of the eyelid 48 hours after a lash appointment. What does this most likely indicate?
Delayed allergic reactions to cyanoacrylate adhesive commonly appear 24-72 hours after application, not necessarily immediately.
