Why Lash Curls Matter

Just like how hairstyles frame the face, lash curls shape the eyes. The right curl can:

Open and lift the eyes.

Create the illusion of bigger, brighter eyes.

Complement or balance natural features.

Personalise the lash look to match a client’s style.

Understanding curls is essential for selecting the right lash design—both for aesthetics and comfort.

Combining Curls

Lash artists often mix curls to correct the way that the natural lashes sit.

Using different curls across the eye will allow you to create a perfect, even lash line. To create the perfect lash line, the correct curl needs to be used according to your clients’ natural lashes. 

Some client’s natural lashes will not all be lifted in the same way – some may sit lower/straighter than others. By using different curls across the eyes, you can correct this.
