This is a wonderful process for enhancing the eyes. Lashes that are straight are not seen. But when gently curled upward in front of the eyelid, a striking difference is made. Eyelashes can be permed to stay curled up to three months. The dye will last approximately 2 months. This process is completely safe, as all products are made strictly to be used on the eyes. They are then dyed black or brown and you're ready to forget the mascara and eyelash curler.
