Why Choose DIAMOND Lash Adhesive?
1–2 Second Drying Time for Greater Control
Not every lash technician needs an ultra-fast adhesive.
The 1–2 second drying time gives you more time to correctly position each extension before the adhesive sets. This makes DIAMOND particularly suitable for beginners and developing lash artists who are still building their application speed.
It can also be an excellent choice for experienced technicians who simply prefer additional control during application.
Strong Bond & Excellent Retention
DIAMOND has been developed to provide a strong, reliable bond when used within its recommended working conditions and with correct lash preparation, application and aftercare.
For the best retention, always ensure the natural lashes are thoroughly cleansed and prepared before application.
Suitable for Classic & Volume Lashes
DIAMOND is a versatile professional adhesive suitable for:
- Classic 1:1 eyelash extensions
- Hybrid lash sets
- Volume eyelash extensions
- Professional salon treatments
- Beginner and intermediate lash technicians
Deep Black Finish
The rich black formula creates a clean, defined lash line and blends seamlessly with black eyelash extensions.

Temperature: 20–25°C

Perfect for Beginner Lash Artists
Choosing an adhesive that matches your working speed is extremely important.
Ultra-fast professional lash glues can begin curing before a developing technician has correctly positioned the extension. DIAMOND’s 1–2 second drying time provides a more forgiving working window, making it easier to concentrate on:
- Correct extension placement
- Direction
- Attachment area
- Isolation
- Clean application
- Consistent lash sets
As your application speed increases, you can explore our range of faster-drying professional lash adhesives.

Lower humidity, cooler conditions or using too much adhesive can contribute to slower curing. Check your salon conditions and make sure they fall within the recommended range.
