Using these VLash B Curl eyelash extensions is easy. First, clean your client's natural lashes to remove any dirt or oil. Then, pick up a single lash extension with a pair of tweezers and apply a small amount of lash glue at the base. Carefully attach the extension to the natural lash, as close to the lash line as possible. You can use them as a full set or mix different lengths for a more natural look. When it comes to maintenance, tell your clients to avoid rubbing their eyes vigorously. They should also stay away from oil - based products around the eye area, as oil can break down the glue. If any extensions start to come loose, it's best to have them fixed by a professional rather than trying to re - attach them at home.
