Lethal Lashes was founded by Cassie, a lash artist and educator who started in the lash industry in 2014.
By 2019, Cassie was fully booked with clients and had students flying in for training. What started as hands-on lash artistry grew into something bigger: a professional lash brand built around better education, stronger products, and real support for lash artists.
Lethal Lashes was not created to follow industry trends. It was created to give lash artists the tools, training, and confidence they need to build a career that actually lasts.
Certified is not the same as confident.
A certificate is only the beginning.
At Lethal Lashes, we believe lash training should create capable, confident artists — not overwhelmed students who leave class unsure of what to do next.
Our training is built around real understanding, real technique, and real-world troubleshooting. We focus on helping students succeed behind the lash bed, because when our students succeed, we succeed too.
Training designed to build lash artists, not overwhelm them.
Lethal Lashes training is built to give students more than one way forward.
Our Classic Lash Certification teaches the foundation every lash artist needs. With one strong classic technique, students can go on to offer five services after certification: classic lashes, hybrid lashes, flat lashes, premade Russian volume, and premade mega volume.
Our Online Russian Volume Training teaches seven techniques, not just one or two. This gives lash artists more options, more flexibility, and a better chance of success if one method does not click right away.
Our Mega Volume Training goes beyond fan-making. Students also learn advanced concepts like Bordeaux and twinning/mirroring techniques, which help with symmetry, balance, and creating a cleaner top line.
Every course is designed with one goal: to help lash artists become skilled, confident, and successful.

Professional products created for real lash rooms.
Lethal Lashes is also home to Black Gold Adhesive, our best-selling professional lash adhesive.
Black Gold was created for lash artists who are tired of babysitting their glue, fighting humidity, and changing their glue drop every 15–20 minutes.
It is a climate-proof adhesive designed to perform in real lash rooms, without humidifier rituals or constant environment stress. Lash artists choose Black Gold because they need consistency, control, and retention they can rely on.
The Lethal Lashes family does not end at certification.
Our students are not just names on a certificate list.
They become part of the Lethal Lashes community — a growing family of lash artists who are building real careers, improving their skills, and creating more opportunity for themselves.
As students grow, some may choose to advance into future opportunities with Lethal Lashes, including becoming trainers, distributors, ambassadors, or brand partners.
We believe in building artists who can grow with us.
