Toronto Eyelash Extensions, Eyelash Extensions Toronto. Lashes Luscious offers Xtreme Lashes® Eyelash Extensions and they are the BEST! (www.xtremelashes.com) All the eyelashes extensions are not the same! Xtreme Lashes® is a revolutionary new product that lengthens and thickens eyelashes. Xtreme Lashes® are single strands of synthetic eyelashes that are bonded to a single natural eyelash. When the natural lash sheds due to the growth cycle, the Xtreme Lash will shed with it. Xtreme Lashes® are not your traditional fake eyelash strips they are semi-permanent individual eyelash extensions. Xtreme Lashes® are applied directly to individual eyelashes, one lashe at a time for a natural look and feel.
