Why Train with The Lash Boutique Academy

Lash Expert

All our training courses are given by Lash Expert, Thereasa Arcari. Having completed her training in New York and London amongst numerous other lash courses. Thereasa has worked in the industry for over a decade and is well known for her in-depth and extensive training.

I love to pass on my experiences, knowledge, tips and tricks that an everyday lash artist will experience. Students feed off my passion for what I do, I love to really get to know my students so I train my students one to one. My students get to feel like a VIP like no other course given. After you’ve completed any of my courses, you’ll come away buzzing and excited to practice your new technique on your clients!
