Retention isn't about luck. It's about control.
If you are an eyelash extension and are about to open a salon or rent a practice/space to carry out your activity, read this article to avoid nerves, stress, and wasted money.
In reality, one of the most important factors—and the most ignored—is the environment in which you work.
You can have:
- premium products
- impeccable technique
- experience
And yet… unstable results. Why?
Because the eyelash extension environment directly influences the reaction of the adhesive.
In this article I will explain clearly:
which spaces you should NOT work in,
why these spaces create real problems
, and how to choose the right space for perfect eyelash extension retention.
1. BASEMENT OR SEMINARY SOIL – THE MOST UNSTABLE ENVIRONMENT
Why it seems ok... but it's not
Many stylists choose the basement for lower costs or quiet.
But from a technical point of view, it is one of the most problematic spaces.
What is actually happening?
- stagnant air → low oxygen level
- soil-influenced humidity
- cold walls + infiltrations
- pipes that change the local temperature
Result: constant micro-fluctuations of the environment of eyelash extensions
Impact on extensions
- the adhesive polymerizes unpredictably
- eyelash extension retention varies from client to client
- unstable results, without clear explanation
You have clients who hold it perfectly and others who fall off in 2 days.
It's not a coincidence. It's the environment.
2. ATTIC – EXTREME VARIATIONS
The main problem: the roof
The attic is directly under the roof, which means:
- rapid overheating in summer
- heat loss in winter
- rapid variations during the day
What influences this?
- temperature → speeds up or slows down eyelash extension adhesive
- eyelash glue humidity → changes with temperature
- the air becomes too dry or too humid
Real impact
- in the morning the adhesive works perfectly
- at lunch they react differently
- evening different behavior
Same technique, different results.
3. OLD BUILDINGS (70–100+ YEARS OLD)
It's not seniority that's the problem...it's structure
Old buildings have a special charm, but technically:
They do NOT provide a stable environment for eyelash extensions
What's happening in the walls
- porous materials (brick, lime)
- absorbs and releases moisture
- lack of modern waterproofing
- uncontrolled ventilation
the walls "breathe" constantly
Environmental impact
- unstable humidity
- uneven temperature in the room
- invisible air currents
you basically have multiple microclimates in the same space
IMPORTANT MYTH: "Old walls are full of germs"
Partially true.
If there is moisture and poor ventilation, mold, spores, bacteria
may appear.
which creates an unstable and stuffy air environment , which can lead to:
- different reactions of the adhesive
- irritation
- tearing (which affects the retention of eyelash extensions)
If you have:
- clients for whom eyelash extensions hold up perfectly
- clients I don't care about at all
It is NOT "bad luck"
It is NOT "bad glue"
it is a clear sign of an unstable eyelash extension environment
4. CLOSED SPACES WITHOUT WINDOWS (SMALL CABINETS, WITHOUT VENTILATION)
"It looks cozy"... but it's one of the most common mistakes
In many eyelash extension salons there are small cabins (e.g. for massage), without windows and without real ventilation.
These spaces are completely unsuitable for eyelash extensions.
What is actually happening?
Lack of ventilation = stagnant air
this leads to:
- decreased oxygen levels
- accumulation of adhesive fumes
- "charged" air
Why space size matters
In a small space:
- air is consumed faster
- humidity increases faster
- the temperature changes more suddenly
the environment is constantly changing during work
Impact on eyelash extensions
- the adhesive reacts differently
- more concentrated vapors → discomfort / irritation
WHAT THE IDEAL SPACE FOR EYELASH EXTENSIONS LOOKS LIKE
A proper space must provide:
Stability, not perfection
Constant temperature: 20–23°C
Stable humidity : 40–55%
Clean air, with controlled circulation
Good insulation
- modern insulated walls
- without infiltrations
- without variations
Proper ventilation
- fresh air
- without direct currents
- without stagnant air
WHAT AN IDEAL SPACE FOR LASH ARTISTS SHOULD HAVE
When choosing a space for eyelash extensions, check:
Glass (required)
- for natural ventilation
- for real air exchange
Air conditioning (or possibility of installation)
- for temperature stabilization
- Does NOT replace ventilation
Sufficient air volume
- avoid very small rooms
- you need circulating air
Ventilation possibility
- opening the window
- constant fresh air
TEST THE SPACE BEFORE YOU RENT
Stay in space for a few hours and check:
- how does the temperature change
- how does humidity change
Go to the viewing with a hygrometer, but also with a mannequin head and eyelash extension glue.
Put a drop of glue on the stone + sticker and monitor the behavior.
You can even request a test day on real clients.
This way you will avoid investing in an unsuitable space for an eyelash extension salon.
You can have:
- the best technique
- the best products
- the greatest experience
But if the gene extension environment is not stable…
the results will NOT be stable and predictable.
TEMPORARY SOLUTIONS (IF YOU ARE ALREADY IN A PROBLEM SPACE)
And here is a list of some products that help you balance the behavior of eyelash extension adhesive and eyelash extension retention, if you are already in such an unstable eyelash extension environment:
- Speed Booster – an "emergency" must-have when you feel like your lashes aren't working. It doesn't have alcohol and you can apply it to both tape in extensions and natural lashes. More details about Speed Booster can be found HERE.
- DO NOT use plastic popsicles as a support for the adhesive. Use a support that is constantly cold: CRYSTAL STONE or JADE STONE, cover with a SPECIAL STICKER for hygiene and comfort.
- Bonder Mist – at the end of the procedure, to close the chemical process faster and increase the retention of eyelash extensions.
- Adhesives with as little vaporization as possible. In the "wrong" spaces, the smell becomes stronger and affects your health. Discover TABYA Lashes Adhesives, which are registered in the European Union's CPNP portal, which means they comply with all regulations and safety standards.
- Don't forget to follow all the preparation steps for application in the following order:
Shampooing with CLEANSING EYE MOUSSE + rinsing with water or saline, microbrush cleaning with CLEANSER CITRIC BOOST, and degreasing with PRIMER.
- And to protect your health from strong fumes, use Block Odor Spray, which neutralizes the chemical compounds evaporated from eyelash extension glue. Find out HERE how to use it correctly.

THE KEY IDEA is that…
Eyelash extensions aren't just about technique. They're about chemistry, physics... and the air around you.
You can control the technique.
You can control the products.
But if you don't control the eyelash extension environment... you lose the result.
