- THICKNESS of liquid substances
Viscosity
- as glue dries viscosity thickens & increases
- WEAKER
- built of smaller molecular unit
Long Chain Polymer
- PROS: less irritation, lower fumes & odor
- CONS: weaker, less durable
- STRONGER
Elastomeric - has elasticity
- better than long chain polymer
- chemical name for family of fast acting adhesives
that SOLIDIFY into an inert (non-reactive) polymer
Cyanoacrylate - only use medical grade biocompatible adhesive -
designed for use on human body
- one of the main causes of irritation
monomer in liquid state
Cyanoacrylate Adhesive
-> once solidifies it becomes a polymer
chains of single repeating units linked together by
Polymers
chemical bonds (the entire pearl necklace)

a molecule that can be bonded to other identical
molecules to form a polymer.
Monomers - repeating units
- building blocks of chain
- (the pearls on a pearl necklace)
Pearl = Monomers
Pearl Necklace Pearl Necklace = Polymer
String = chemical bonds holding everything together
process in which monomers link together creating
Polymerization Reaction polymer
- adding water can catalyze reaction
- colorless gas with sharp suffocating odor
- toxic to humans -> causes cancer
Formaldehyde
- a gas that can be absorbed through mucous
membrane of inner eyelids
process of keeping single NL set apart from others by
Isolation
tweezers
- any membrane lining passages of body that open to
the outside
Mucous Membrane - ex: eyes, ears, nose, mouth
(mucosa) mucous membrane secrete mucous - fluid lining
membranes that moisten tissue and protects from
infection
1. Create positive long term results
2. Ensure Desirable Immediate Results
3. Reduce risks of adverse reactions
4. Complete quick & comfortable application for
? BEST PRACTICES (7) 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 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
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
Separation Technique
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
use of manual dying bulb to dry a wet lash
?Alternative Technique
TIME CONSUMING
twist & peel off loose extensions
Dry Removal/Twist & Peel
- make sure no loose unbonded bases, it can irritate
Technique
clients eyes
time between application of a full set and when they
Longevity
begin shedding naturally then requiring fill or new set
select extensions based off Client's DESIRES +
Choosing Set
Extensionist's ADVICE
discuss with client prior to starting application, reach
Realistic Expectations
an understanding before starting
offers best long term results
Three Length Bonding - uses the lash growth cycle: Anagen, Catagen,
Technique Telogen
- uses 3 lengths of extensions
Anagen - growing baby lashes (SHORTEST)
Lash Growth Cycle (3 Catagen - resting phase (MEDIUM)
Stages) Telogen - mature phase involving shedding (LONG)
