We at Lash Theory believe the modern beauty industry should look to the future in order to evolve. This is why we created a new, innovative DIY lash extension system for the busy, savvy, stylish and hardworking woman who wants to feel put-together on a daily basis. The Lash Theory System allows you to apply lashes yourself, customize your style, and wear the lashes for 5-7 continuous days without damaging your natural eyelashes. Each lash segment is to be applied underneath the natural eyelash for a seamless look. The uniquely designed lashes and adhesive bond work together to form a waterproof seal that will last through showers, workouts, and daily activities. The lashes are handcrafted with a blend of high-grade synthetic fibers that are made to perfection. The thin, black flexible band will create a seamless, weightless and comfortable look. Each set of lash segments help you to create a 3D effect. Achieve full and beautiful looking lashes every single time. Guaranteed to compliment every eye shape!
