Lashes are typically made from synthetic fibers (like PBT), silk, mink fur, faux mink, or even human hair. The best material depends on your desired look, comfort level, ethics, and budget—faux mink and silk are often preferred for their balance of quality, comfort, and cruelty-free appeal.
Why Lash Material Choices Matter for Clients and Artists
Choosing the right lash material isn’t just about beauty—it’s about comfort, safety, ethics, and personal style. Whether you’re applying lashes at home or in a professional setting like at Bela Beauty College, understanding your options is essential. For instance, knowing what is lash lift and how it differs from lash extensions can help clarify the right approach for different clients. Each lash type behaves differently on the eye, responds to glue and heat uniquely, and speaks volumes about your brand or personal values.
Understanding Different Lash Materials
There’s no one-size-fits-all answer when it comes to lash material. Here’s what you need to know about the most common options.
1. Synthetic Lashes (PBT)
-
Made from Polybutylene Terephthalate, a durable thermoplastic polymer
-
Glossy, holds curl well, stiffest among all types
-
Most affordable, great for a dramatic, full-volume look. These are also a common focus in professional lash training, like our Classic, Hybrid and Premade Volume Lash Course, where students learn how to apply bold sets with confidence.
-
Heat- and water-resistant
Best For:
-
Clients who want bold, dense lashes
-
Lash sets needing strong curl retention
- Budget-conscious applications
2. Silk Lashes
-
Technically synthetic, but with a lighter, softer, and more natural finish than regular synthetic
-
Semi-matte finish
-
Tapered more gradually than synthetic lashes
-
More flexible and comfortable on the eye. Because silk lashes are often used for elegant, softer designs, they’re taught in detail during our Volume Lash Course for artists who want to master refined applications.
Best For:
-
Special occasions
-
Clients seeking a soft, elegant look
- Those with semi-sensitive eyes
3. Mink Lashes (Real Mink)
-
Made from brushed mink fur (often Siberian or Chinese mink)
-
Ultra-lightweight, soft, fluffy, and very natural-looking
-
Don’t hold curl well without curling tools
-
Require extra care (not water-resistant)
Ethical Concerns:
-
Real mink lashes involve animal fur—raising concerns about animal cruelty
-
Not vegan or cruelty-free
Best For:
-
High-end clientele wanting luxurious, feathery looks
- Clients OK with ongoing maintenance
4. Faux Mink Lashes
-
Made from high-quality synthetic fibers designed to mimic real mink
-
Vegan and cruelty-free
-
Hold curl well and are more durable than real mink. At Bela Beauty College, we emphasize these materials in our training, especially within the Mega Volume Lash Course, where students perfect dramatic, full looks while staying cruelty-free.
-
Slightly more affordable than real mink
Best For:
-
Clients who want luxury without compromising ethics
- Lash artists focused on vegan or cruelty-free services
5. Human Hair Lashes
-
Made from sterilized, cleaned, and processed human hair
-
Extremely lightweight and soft
-
Most natural-looking among all options
-
Rare in lash extensions; more common in strip lashes
Best For:
-
Hyper-natural looks
-
Sensitive eyes
- Custom and minimalist lash designs
How Lash Extensions Are Manufactured
The way lashes are made plays a huge role in their quality and performance.
Synthetic and Faux Mink Lashes:
-
Created using PBT extrusion
-
Molded into specific curls
-
Heat-treated to set shape
-
Often go through multi-layering to add volume
Silk Lashes:
-
Produced similarly to faux mink but with additional tapering steps
-
Coated for a semi-matte finish
Real Mink Lashes:
-
Collected through brushing live animals (though the ethics of this are debated)
-
Handcrafted and shaped without heat
Human Hair Lashes:
-
Sterilized, sorted, and woven into lash bands or fibers
- Hand-tied in some cases for custom shapes
Comparing Lash Materials Side by Side
Ethical & Environmental Considerations
More clients today want lashes that align with their values—and that includes how they’re made.
Concerns with Mink:
-
Even if labeled “cruelty-free,” most mink lashes come from fur farms
-
No lash is truly cruelty-free if it uses real animal fur
Cruelty-Free Alternatives:
-
Faux mink and silk lashes offer a luxurious look without the ethical baggage
-
Look for certifications or transparent brand sourcing
Environmental Factors:
-
Synthetic lashes are not biodegradable
-
Some emerging brands now offer recyclable packaging and biodegradable lash trays
At Bela Beauty College, we educate our students and clients about the importance of ethical beauty. We prioritize using and teaching techniques with cruelty-free, sustainable materials.

Common Materials:

Pre-glued strips or individual clusters

Latex or acrylic-based glue (some may cause irritation)
How to Choose Wisely:

-
Avoid kits with poor packaging or missing ingredient labels
-
Choose known brands that disclose materials and safety testing

Do a patch test before using the glue

Never reuse lashes beyond their intended lifespan
