Lash Rx brings the best eyelash extensions to the Dallas/Fort Worth Metroplex. Eyelash extensions are a great semi-permanent alternative to mascara, expensive & dangerous lash serums, and costume false eyelashes, and can extend the length and thickness of your lashes. With a full-set of extensions, there is no need to use lash curlers or mascara. Eyelash extensions are perfect for everyday wear as well as special occasions. With proper care and touch-up visits, your eyelash extensions can last a very long time! Touch-ups vary from person to person, typically anywhere between 2-4 weeks. Your natural lash cycle, as well as how you take care of your lashes, will affect how long your extension will last.
