A two-week manicure? It’s a beach holiday dream come true, courtesy of Shellac, the American (of course) nail system. Have the gel (by Creative Nail Design) painted on to your nails, cure it for a few minutes under UV light and done. Available in fourteen colours, it won’t chip, smudge, dull or damage your nails. Here are three salons offering it now.
