Best shellac manicure I've gotten in Toronto. RT (or Arty?) is the best - I go her for threading, waxing and manicures. They use bio seaweed gel here which is a healthier shellac as it contains no "no formaldehyde, toluene, DBP, BHA or camphor. This means there is zero dehydration, staining or weakening of the natural nails." The application is thin which I love so you don't end up with chunky shellac.
Price isn't bad too I think it was 35$ for shellac manicure!
