The 6-Week Advanced Extension
Certification
A Complete Certification + Mentorship Experience
Elevate your artistry with this fully guided 6-week certification designed for lash artists who are ready to move beyond basic technique and step into true professional mastery.
We’ve thoughtfully built every detail of this program to help you feel confident, supported, and fully prepared to take clients at a higher level. Inside, you’ll receive three in-person mentorship sessions, lifetime access to our Ultimate Lash Course, a professional kit valued at over $525, and a complete business launch system — all within an intimate small-group setting of just three artists.
Starting with advanced lash theory, precision styling, retention science, timing strategies, and corrective techniques, each session builds upon the last. You won’t just practice — you’ll refine, adjust, and master your craft with real-time feedback and personalized mentorship.
By the end of six weeks, you won’t just feel “better.” You’ll feel certified, confident, and capable of delivering consistent, beautiful lash sets — every time.
