What is a recommended best practice for reducing allergic reaction risk with new, first-time clients?
Answer: Performing a patch test 24-48 hours before the first full service
A patch test 24-48 hours before the first full service is a widely recommended best practice for identifying sensitivity before a full application.
What defines a 'volume' lash set as opposed to a classic set?
Answer: Applying multiple lightweight extensions fanned onto one isolated natural lash
Volume sets apply multiple ultra-fine extensions fanned onto a single isolated natural lash, rather than one extension per lash.
Which mapping style places the longest lengths progressively toward the outer corner for an elongated, lifted look?
Answer: Cat eye map
Cat eye mapping increases length toward the outer corner, creating a lifted, elongated effect.
What is the single biggest cause of poor lash extension retention on the client's side?
Answer: Oil-based skincare or makeup removers near the eyes
Oil-based products (skincare, makeup, cleansers) break down cyanoacrylate bonds and are the most common client-side retention killer.
What is a 'stickie' in lash extension terminology?
Answer: An extension accidentally bonded to more than one natural lash
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.
A client reports redness and swelling of the eyelid 48 hours after a lash appointment. What does this most likely indicate?
Answer: A possible delayed allergic reaction to the adhesive
Delayed allergic reactions to cyanoacrylate adhesive commonly appear 24-72 hours after application, not necessarily immediately.
How long should a client generally avoid water and steam after a fresh full set?
Answer: Roughly 24-48 hours
Standard aftercare guidance is to avoid water, steam, and sweating for roughly the first 24-48 hours while the adhesive fully cures.
What is the primary purpose of isolation technique?
Answer: To separate one natural lash from its neighbors so the extension bonds to it alone
Isolation separates a single natural lash from its neighbors so the extension bonds to only that one lash, preventing stickies and uneven shedding.
Which items should be treated as single-use and discarded after each client?
Answer: Under-eye pads, micro-brushes, and adhesive rings
Under-eye pads, micro-brushes/mascara wands, and adhesive rings/palettes are single-use and should never be reused between clients.
As a general safety guideline, how much longer than the natural lash should an extension be?
Answer: No more than about 2mm longer
A widely taught rule of thumb is no more than about 2mm longer than the natural lash, to avoid overloading and damaging it.
Which statement about lash extension licensing is most accurate?
Answer: Requirements vary by state/jurisdiction and must be verified with the local licensing board
Licensing requirements for lash extension services vary significantly by state/jurisdiction, so a technician must verify requirements with their own state board.
What is the main reason lash extensions eventually shed even with perfect application?
Answer: The natural lash it's bonded to completes its growth cycle and sheds
Natural lashes cycle through growth, transition, and resting phases and shed naturally roughly every 100 days; the extension sheds along with the natural lash it's bonded to.
Which of the following is a required practice for tool sanitation between clients?
Answer: Disinfecting tweezers with an EPA-registered hospital-grade disinfectant between every client
Reusable metal tools like tweezers must be cleaned of debris and disinfected with an EPA-registered hospital-grade disinfectant between every client.
Which of these is generally considered a contraindication requiring the service to be postponed?
Answer: An active eye infection such as conjunctivitis
An active eye infection like conjunctivitis is a contraindication and the service should be postponed until it's fully resolved.
What is lash adhesive chemically based on?
Answer: Cyanoacrylate
Professional lash adhesive is a cyanoacrylate-based formula that cures through a reaction with moisture in the air.
Which curl type is most commonly requested for a classic, natural-glam lash look?
Answer: C curl
The C curl provides a noticeable, eye-opening curl that reads as natural-glam and is the most commonly requested curl overall.
Why is a consultation an essential first step, not a formality?
Answer: It identifies allergies, contraindications, and sets realistic expectations before the service starts
A thorough consultation catches allergies, contraindications, and unrealistic expectations before the service begins, protecting both client and technician.
Roughly how far from the lash base should adhesive be placed?
Answer: Roughly 1-2mm from the lash base
Adhesive should be placed about 1-2mm from the lid margin/lash base — never touching the skin directly.
