Shellac manicures have been available for quite some time now with new product lines, colors and textures hitting the salons.
CONS: Each coat of polish requires a UV light to dry causing a longer visit to the salon. The re-growth is a little bothersome and tends to lift slightly at the cuticle. Removal of this manicure is vexing. It can be taken off at a salon or at home with a bottle of acetone. Each finger is wrapped in acetone-soaked cotton for ten minutes then rubbing and scraping are needed to finish the job.
The Shellac manicure does last a very long time and would be great before a long vacation, no touch-ups needed. However, for me, it is not worth the extra time, money or the tourture.
