Not sure about Calis for shellac, need to find someone with experience or it is a waste of money. I tried it once in Fethiye and then had to go up to Goldfinger in Ovack and get it done again, the girl in Fethiye had no idea what she was doing, she also charged me quite a lot.
I think maybe the Hairdresser next to the Cahide Bar has a sign outside for nails?
