Nouveau Lashes are lash extensions designed to give you thicker, longer and natural looking lashes. They are not false lashes or cluster lashes. Nouveau Lashes are very fine, perfectly shaped made to look like a natural lash. One Nouveau Lashes extension is applied at a time using a special adhesive, directly on to your natural eyelash, in a specific sequence. This process is repeated until you have a full set and takes around 2 hours to complete.
