Eyelash extensions developed by a lash technician

Eyelash extensions are the foundation of any lash treatment. At BeautyByDau, our lashes are not just another product – they are developed with a real challenge in mind.

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. She often had to buy glue in one place, lash trays in another, and accessories in a third place – and the quality was not the same.

That's exactly why the shop was created.

The goal was to bring together eyelash extensions and professional eyelash equipment in one place, where the quality was tested, thoroughly developed and approved in practice.


Professional, high-quality eyelash extensions

Our eyelash extensions are selected and tested in a clinic environment. They are developed to provide:

  • Stable shape

  • Uniform curl

  • Easy fan construction

  • Beautiful black finish

  • Minimal variation in the hills

You will find, among other things:

  • Single flat lashes

  • YY lashes

  • Easy fan volume lashes

  • W lashes

All in multiple lengths, thicknesses and curls, so you can create everything from natural looks to full volume.


Designed for performance – not just looks

Beautiful lashes aren't enough. They also need to be easy to work with.

When you work professionally with eyelash extensions, you know that small differences matter:

  • How easily do the lashes come off the strip?

  • Whether the curl holds its shape

  • Whether the thickness is uniform

  • Whether the trays are stable in quality

That's why our lashes are selected with a focus on workflow and efficiency - not just finish.


One unified system

One of the biggest frustrations as a new lash technician is combining products from different suppliers that don't always work optimally together.

At BeautyByDau, the idea is different.

Our eyelash extensions are part of a complete system where:

  • Eyelashes

  • Glue

  • Primer

  • Farmer

  • Accessories

are selected to work together.

This creates more stable retention and more predictable results.


For both new and experienced technicians

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 put together exactly the look you want without compromising on quality.


Uniform quality in every tray

A common problem in the industry is variation in quality from tray to tray.

Therefore, the focus is on:

  • Stable production

  • Uniform thickness

  • Consistent curl

  • Easy removal from strip

This makes your workflow faster and more accurate.


Create better retention

Eyelash extensions are only as good as their combination with the correct pre-treatment and glue. When the products work together, they create:

  • Better bonding

  • Less shedding

  • Longer shelf life

  • More satisfied customers

It's not just about selling lashes – it's about creating a stable result.


Based on experience from the clinic

BeautyByDau's eyelash extensions are 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 needs.

That's the difference between random quality and well-crafted quality.
