TDLR Lash Extension Written Exam Updated Test
Bank and Answers (A+ Guaranteed)
• Long Chain Polymer -✓✓- WEAKER
- built of smaller molecular unit
- PROS: less irritation, lower fumes & odor
- CONS: weaker, less durable
• Elastomeric -✓✓- STRONGER
- has elasticity
- better than long chain polymer
• Cyanoacrylate -✓✓- 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 -✓✓monomer in liquid state
-> once solidifies it becomes a polymer
• Polymers -✓✓chains of single repeating units linked together by chemical bonds (the
entire pearl necklace)
• Monomers -✓✓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 -✓✓Pearl = Monomers
Pearl Necklace = Polymer
String = chemical bonds holding everything together
• Polymerization Reaction -✓✓process in which monomers link together creating
polymer
- adding water can catalyze reaction
• Formaldehyde -✓✓- colorless gas with sharp suffocating odor
- toxic to humans -> causes cancer
- a gas that can be absorbed through mucous membrane of inner eyelids
• Isolation -✓✓process of keeping single NL set apart from others by tweezers
,• Mucous Membrane (mucosa) -✓✓- 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) -✓✓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 -✓✓Making sure there's no loose bases or stickies
• Loose Base -✓✓end of extension failed to bond with NL
• Removal Solution -✓✓liquid that dissolves eyelash adhesive
• Separation Technique -✓✓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 -✓✓use of manual dying bulb to dry a wet lash
TIME CONSUMING
• Dry Removal/Twist & Peel Technique -✓✓twist & peel off loose extensions
- make sure no loose unbonded bases, it can irritate clients eyes
• Longevity -✓✓time between application of a full set and when they begin shedding
naturally then requiring fill or new set
• Choosing Set -✓✓select extensions based off Client's DESIRES + Extensionist's
ADVICE
• Realistic Expectations -✓✓discuss with client prior to starting application, reach an
understanding before starting
, • Three Length Bonding Technique -✓✓offers best long term results
- uses the lash growth cycle: Anagen, Catagen, Telogen
- uses 3 lengths of extensions
• Lash Growth Cycle (3 Stages) -✓✓Anagen - growing baby lashes (SHORTEST)
Catagen - resting phase (MEDIUM)
Telogen - mature phase involving shedding (LONG)
REMEMBER - ACT*
• 3 Length Bonding vs. 1 Length Bonding -✓✓- 3 offers more natural, lasts longer, still
looks good during shedding
- 3 helps create stronger base and dark lash line
- 1 looks artificial, tangles, no dark lash line - is sparse, unnatural
• Short Extensions -✓✓provide structure and support for longest extensions
• One Growth Cycle -✓✓takes up ~30% of lashes on one eye
- if fail to bond short lashes or longest - missing 60% of application
• 5 Reasons for Using 3 Length Bonding -✓✓1. allows extensions to look their best
throughout duration
2. decreases amount of work during a fill
3. allows ALL NL to be bonded for max thickness
4. allows shortest lashes to fill in gaps of lash line
5. allows NL to grow, rest, shed, naturally
• Removal/Touch Ups/Fills -✓✓after 4 weeks, 50% remain and new hairs grow in
- process involves bonding to new growth and removing lifting extensions
• Shocked/Shock Cured -✓✓white residue that forms when glue is shocked by direct
application of water/tears
• Navarro Touch Up Technique -✓✓1. Separate: look for new growing lashes, separate
any ext that may have stuck together, look for grown out ext.
2. Twist & Peel grown out ext. more than 3-4 mm
3. Apply New Ext.
4. Finish touch up
*NO NEED FOR LIQUID REMOVAL
• Glove Technique -✓✓-place glue drop as close to knuckle on back of gloved hand
- prevents glue from drying up as its airmailed to client's face from glue tray
• Choosing Good Adhesive -✓✓- must be packaged in way that prevents formation of
formaldehyde
- know where glue is made
