I have short nails and every so often I like them to be spruced up at the nail bar. I say I want gels, choose a colour and colour me out happy. However, I have recently spoken to a number of people having their nails done who say they have acrylics done and that they wish they had them done ages ago.I always though acrylics were those really artificial-looking nails but apparently you can have them looking very natural. Rather than gels, should I have acrylics? Can I have them done over and over again every time I want a new nail? How easy is it to go back to natural once that you have acrylic done? Are they very expensive?
