Specialty curls have become a hot trend in the lash industry. While C, CC, and D curls remain the classics, lash artists are increasingly turning to special curls like L+, V, and now M1 curl for more dramatic, eye-opening effects.
The M1 curl premade fan is designed specifically for lash artists who want instant lift, bold styling, and maximum impact — all with the convenience of premade fans. With a steeper, sharper curve than the standard M curl, M1 lashes are ideal for cat eye lash maps, correcting downward lashes, and creating bold volume sets that stand out.
In this guide, you’ll learn everything about M1 curl lashes in premade fans: what makes them unique, who they suit best, how they compare with other curls, and professional tips for application and styling.
What Are Premade Fans in Eyelash Extensions?
Premade lash fans are clusters of multiple lash extensions pre-fanned and bonded at the base during manufacturing. Instead of hand-making fans at the lash bed, artists can pick them directly from the tray and apply them.
Benefits of using eyelash extensions premade fans:
- Faster application → serve more clients in less time.
- Consistent symmetry and curl → every set looks flawless.
- Available in 2D to 20D → from natural volume to mega volume.
- Stable curls → heat-set during production to maintain shape.
What Is M1 Curl in Lash Extensions?

The M1 curl is a specialty upgrade of the M curl. It has:
- A slightly straight base for strong adhesive bonding.
- A sharper upward lift than M curl, starting close to the base.
- A more defined curve that creates an instantly wide-eyed, lifted look.
Compared with M curl lashes, M1 curl lash extensions are bolder and more dramatic, making them ideal for standout lash sets.
