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.
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.
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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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 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.
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.
