Dramatic Eyelash Extensions will give you longer, bold and very thicker looking eyelashes. With proper care and touchup visits they can last INDEFINITELY. Normally a person's natural eyelash falls out every 60 - 90 days and a new lash grows in immediately. Therefore, it is necessary to get touch-ups to fill in the fallen lashes. About every 2 to 4 weeks is recommended, however, this will vary from person to person. There is no need for mascara even though a water based mascara is fine to use. The lashes are made from synthetic fibers and they are safe in the shower, while swimming, sleeping or exercising. Let the Lash Queen Enhance your beauty to look and feel FABULOUS all day everyday.
