I'm thinking about my future and which way to go with training. I am a qualified Nail Tech, but so want to be good at what I'm doing. I really like NSI Acrylic, but the courses for NSI are really far away and don't sound very indepth. My other option is CND courses, closer to home, but not sure if I like the sounds of retention liquid and powder, guess I would get used to it. At least there courses sound more indepth. Any feedback from people who have done either or these would be great.
