As a dedicated lash manufacturer, we understand the pivotal role that eyelash extension adhesives play in the beauty industry. The choice of glue not only affects the durability and appearance of lash extensions but also ensures the safety and comfort of clients. In this article, we delve into the What Glue Do Lash Techs Use, their compositions, and best practices to ensure optimal results.
What is Lash Glue
Lash glue is a special adhesive used to attach false eyelashes—either strip lashes or individual lash extensions—to the natural lash line or individual natural lashes. It plays a crucial role in the lash application process, ensuring that the lashes stay in place securely and comfortably for the desired duration.
Types of Lash Glue
- Strip Lash Glue
- Used for temporary false eyelashes (usually worn for a day).
- Comes in tubes or brush-on applicators.
- Dries clear or black.
- Can be latex-based or latex-free (for sensitive skin).
- Lash Extension Glue
- Used by professional lash technicians for semi-permanent eyelash extensions.
- Contains cyanoacrylate, a strong, fast-drying adhesive.
- Designed to bond individual lash extensions to each natural lash.
- Offers long-lasting hold (4–8 weeks).
Type of Glue Used by Lash Techs
Lash adhesives are not one-size-fits-all. Depending on the environment, client needs, and lash artist’s skill level, different glues perform better in certain conditions.
A. Cyanoacrylate-Based Glues (Most Common)
- What it is: The standard adhesive for lash extensions, made from cyanoacrylate, a fast-bonding acrylic resin.
- Best for: Classic, volume, and hybrid lashes.
- Drying time: 1-3 seconds (fast-curing).
- Key benefit: Strong hold (lasts 3-6 weeks).
- Drawback: Can cause irritation if not formulated properly.
B. Latex-Free & Formaldehyde-Free Glues
- What it is: A hypoallergenic alternative for sensitive clients.
- Best for: Clients with allergies or watery eyes.
- Drying time: 2-4 seconds (slightly slower).
- Key benefit: Gentler on sensitive eyes.
- Drawback: May not last as long as cyanoacrylate glues.
C. Sensitive or “Low-Fume” Glues
- What it is: Reduced chemical fumes for a more comfortable application.
- Best for: New lash techs or clients prone to irritation.
- Drying time: 3-5 seconds.
- Key benefit: Less eye-watering during application.
- Drawback: Weaker bond (may require more frequent fills).
D. Black vs. Clear Lash Glue
- Black glue: Helps blend with dark lash lines, ideal for volume sets.
- Clear glue: Best for natural looks or clients with light lash lines.
Key Features Lash Techs Look For
Not all lash glues are equal. Here’s what professional lash techs look for:
A. Retention Strength (How Long It Lasts)
- High-retention glues (3-6 weeks): Best for humid climates or oily skin clients.
- Medium-retention glues (2-4 weeks): Ideal for normal to dry skin.
B. Drying Time (Speed of Cure)
- Fast-drying (1-2 sec): For experienced techs who work quickly.
- Medium-dry (2-4 sec): Best for beginners.
- Slow-dry (5+ sec): Rare, used for mega volume sets.
C. Humidity & Temperature Compatibility
- Humidity-activated glues: Work best at 40-70% humidity (most professional glues).
- Non-humidity-dependent glues: Rare but useful in dry climates.
D. Fume Levels & Eye Safety
- Low-fume glues: Reduce irritation for clients and techs.
- Medical-grade adhesives: Highest safety standards (recommended for sensitive clients).

- Patch Testing: Always conduct a patch test 24–48 hours before the full application to check for allergic reactions.

FAQ
How to Remove Glue from Lash Extensions
To remove glue from lash extensions safely, it’s best to use a professional lash glue remover, especially if the extensions were applied with strong cyanoacrylate-based adhesive. Apply the remover with a microfiber applicator or lash wand, gently isolating the lashes to avoid contact with the skin or eyes. Let the product sit for a few minutes to break down the adhesive, then slide off the extensions carefully. Do not pull or rub, as this can damage natural lashes. If you’re unsure, always have a professional do the removal to protect your natural lash health.
What Glue Is Used for Lash Extensions
Lash technicians typically use cyanoacrylate-based glue for lash extensions. This type of adhesive offers a strong, long-lasting bond and fast drying time. The most common variants are ethyl, butyl, and alkoxy cyanoacrylate, each with different fume levels, drying speeds, and suitability for sensitive clients. High-quality lash extension glues are medical-grade, formaldehyde-free, and designed specifically for use around the delicate eye area. These adhesives can keep lash extensions in place for up to 6–8 weeks when applied properly under ideal conditions.
Is lash extension glue different from lash glue?
Lash Extension Glue
This is a professional-grade adhesive used to attach individual lash extensions to natural lashes. It contains cyanoacrylate, which provides a very strong, long-lasting bond—often lasting 4 to 8 weeks. Lash extension glue dries very quickly, is designed for precision, and should only be used by trained lash technicians. It’s not safe for DIY use, as improper handling can cause eye irritation or lash damage.
Regular Lash Glue (Strip Lash Glue)
This glue is used for temporary strip lashes that are worn for a day or an event. It’s gentler, usually latex-based or latex-free, and meant to hold lashes in place for a few hours. It’s easy to apply and remove at home without damaging natural lashes. Strip lash glue is safe for everyday users and washes off easily with warm water or makeup remover.
Conclusion
As a professional lash manufacturer, we recognize the critical role adhesives play in delivering exceptional lash services. By understanding the properties of various cyanoacrylate types and considering client-specific needs, lash technicians can ensure safe, durable, and beautiful results. Continuous education and staying updated with industry innovations are key to mastering the art of eyelash extensions.
