TDLR LASH EXTENSION EXAM 2026
COMPREHENSIVE PRACTICE ASSESSMENT
◉ 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
◉ ?Alternative Technique. Answer: use of manual dying bulb to dry a
wet lash
TIME CONSUMING
◉ Dry Removal/Twist & Peel Technique. Answer: twist & peel off
loose extensions
- make sure no loose unbonded bases, it can irritate clients eyes
