Eyelash extensions are the foundation of any lash treatment. At BeautyByDau, our lashes are not just another product – they have been developed based on a real-world challenge.
When Emilie Dau Thomsen became a certified lash technician, she experienced how difficult it was to find the right lashes, the right glue, and the right equipment that worked together. Often, she had to buy glue in one place, lash trays in another, and accessories in a third – and the quality was inconsistent.
That was precisely why the shop was born.
The goal was to gather eyelash extensions and professional lash equipment in one place, where the quality was tested, thoroughly refined, and approved in practice.
Our eyelash extensions are selected and tested in a clinical environment. They are developed to provide:
Stable shape
Consistent curl
Easy fan creation
Beautiful black finish
Minimal variation in the trays
You will find, among others:
Single flat lashes
YY lashes
Easy fan volume lashes
W lashes
All available in multiple lengths, thicknesses, and curls, so you can create everything from natural looks to full volume.
Beautiful lashes are not enough. They must also be easy to work with.
When you work professionally with eyelash extensions, you know that small differences matter:
How easily the lashes release from the strip
Whether the curl holds its shape
Whether the thickness is uniform
Whether the tray quality is stable
That is why our lashes are selected with a focus on workflow and efficiency – not just the finish.
One of the biggest frustrations as a new lash technician is combining products from different suppliers that do not always work together optimally.
At BeautyByDau, the approach is different.
Our eyelash extensions are part of a cohesive system where:
Lashes
Glue
Primer
Bonder
Accessories
are selected to function together.
This creates more stable retention and more predictable results.
Regardless of whether you are new to the industry or an experienced stylist, proper quality is essential.
Our eyelash extensions are suitable for:
Classic single lashes
Hybrid sets
Volume sets
Wispy looks
Mega volume
You can assemble exactly the look you want without compromising on quality.
A recurring problem in the industry is variation in quality from tray to tray.
Therefore, we focus on:
Stable production
Uniform thickness
Consistent curl
Easy removal from strip
This makes your workflow faster and more precise.
Eyelash extensions are only as good as their combination with proper pre-treatment and glue. When the products work together, it creates:
Better bonding
Less shedding
Longer durability
More satisfied clients
It is not just about selling lashes – it is about creating a stable result.
BeautyByDau’s eyelash extensions were not developed theoretically – they are based on real experience from treatments.
When you choose lashes from here, you choose products that have been tested in practice and adjusted based on real-world needs.
That is the difference between random quality and thoroughly refined quality.
