DIY eyelash extensions (also known as temporary lashes, semi-permanent or false lashes) are individual lash clusters that are easily applied one by one to the under or upper side of the natural lash line with a semi-permanent adhesive. The Citizen Lash system helps to create longer, fuller looking lashes that will last up to 5 days without removal. To apply an entire lash set, place anywhere from 2-6+ lash clusters to each eye. Each lash set is reusable up to 10+ times and the learning curve for DIY lashes is not extensive, anyone can do it.
