Having used both systems I have to say that I don't think getting a try me kit is going to help you, I say this because without the training you are unlikely to get the best out to your kit.
Creative is a lovely product to use but is different from nsi, you don't say why you want to change your product but what ever the reason I can promise you that a days 121 training with Creative would be money well spent, you really can't beat having a master tech giving you their undivided attention.
THIS I agree with! Best is personal, what is best for you maybe terrible for me, but I will say you cannot take away from CND that they are Global leaders, Consider the Nail Tech with every product and Fab education and SATISFY the clients needs. How many companies can offer that?
This thread does have a stupid title is CND the best blah blah blah! Why dont you want to know HOW we came to think CND is the best, what does it do for us above other products?!
I started in the industry with NSI and its ok tho not Fabulous. The l&P seems grainy to me, it doent flow as nicely as CND or Young Nails who I also use. The gel I cannot get on with at all.
I started with CND's solar mani range and some enamels as couldnt afford to change completely, I teach with young so use young and got exceptional results. I needed more coverage and knew CND had fantastic custom blend products so made the switch to their l&p and along the way learnt Brisa which is blowing my mind its that good!
Along my career these are the 3 main products but I have tried a few others (I also think Fusion is a good budget range that gives good results) You must trial something properly, when I first got Brisa last Nov I couldnt quite get th eresults I got with Young and with Christmas looming I switched back, now I've had time to ask questions, put into practice what I've been told and am getting fantastic results. Its early days so by next month I should have gotten some good feedback from my clients.
Its not an easy desicion choosing who to go with - for me it has to be the one that gives me EVERYTHING I want and more!
I hope this helps.
