TDLR LASH EXTENSION EXAMS SET 2026
COMPLETE QUESTIONS AND ANSWERS
BUNDLED PREMIUM RESOURCE
●● Long Chain Polymer.
Answer: - WEAKER
- built of smaller molecular unit
- PROS: less irritation, lower fumes & odor
- CONS: weaker, less durable
●● Elastomeric.
Answer: - STRONGER
- has elasticity
- better than long chain polymer
●● Cyanoacrylate.
Answer: - chemical name for family of fast acting adhesives that
SOLIDIFY into an inert (non-reactive) polymer
- only use medical grade biocompatible adhesive - designed for use on
human body
- one of the main causes of irritation
,●● Cyanoacrylate Adhesive.
Answer: monomer in liquid state
-> once solidifies it becomes a polymer
●● Polymers.
Answer: chains of single repeating units linked together by chemical
bonds (the entire pearl necklace)
●● Monomers.
Answer: a molecule that can be bonded to other identical molecules to
form a polymer.
- repeating units
- building blocks of chain
- (the pearls on a pearl necklace)
●● Pearl Necklace.
Answer: Pearl = Monomers
Pearl Necklace = Polymer
String = chemical bonds holding everything together
●● Polymerization Reaction.
Answer: process in which monomers link together creating polymer
- adding water can catalyze reaction
,●● Formaldehyde.
Answer: - colorless gas with sharp suffocating odor
- toxic to humans -> causes cancer
- a gas that can be absorbed through mucous membrane of inner eyelids
●● Isolation.
Answer: process of keeping single NL set apart from others by tweezers
●● Mucous Membrane (mucosa).
Answer: - any membrane lining passages of body that open to the
outside
- ex: eyes, ears, nose, mouth
mucous membrane secrete mucous - fluid lining membranes that
moisten tissue and protects from infection
●● ? BEST PRACTICES (7).
Answer: 1. Create positive long term results
2. Ensure Desirable Immediate Results
3. Reduce risks of adverse reactions
4. Complete quick & comfortable application for client
5. Apply maximum # of extensions in allotted time (goal = bond every
lash)
, 6. Spend reasonable amount of time on application
7. Do NOT damage NL
●● Clean Up Technique/Cleaning Up.
Answer: Making sure there's no loose bases or stickies
●● Loose Base.
Answer: end of extension failed to bond with NL
●● Removal Solution.
Answer: liquid that dissolves eyelash adhesive
●● Separation Technique.
Answer: needs at least 4 rounds
- critical part of delivering high quality results
- keeps lashes apart from others
- ensures every NL is free to grow and stay healthy
- ensures every lash is bonded
stuck lashes = can't grow and become damaged
- remove extension to extension, extension to NL, cluster of extensions
- helps reveal hidden NL
- helps fluff up appearance of extensions
