Yes. You can have lash extensions added to your Nouveau Lash Enhance/LVL Lashes. In fact, Nouveau Lash Enhance/LVL treatments are particularly good for people who want lash extensions, but have downward-pointing lashes. Lash extensions can cause downward-pointing lashes to lower even further. With LVL they can get the essential lift they need before the extensions are added. Don’t forget though – you must wait 48 hours after an Nouveau Lash Enhance/LVL treatment before having lash extensions applied.
