Semi-permanent
When properly applied, Xtreme LashesTM Eyelash Extensions last up to two months. That's why they are called "semi-permanent" extensions. Typically, a natural eyelash lasts between 6 to 12 week before falling out and being replaced. At any given moment, each eyelash is in a different stage of its life cycle. Touch-ups replace the eyelashes that have completed their cycle. For optimal results, touch-ups must be done every 3 to 6 weeks.
