Hi hon!
I trained with the Herts and Essex Academy in Nouveau Contour two years ago. It was ok training, they missed out a few bits but it is much cheaper than actually training with Nouveau themselves. I've only ever used Nouveau but their products are very good, glue is fantasic, lashes stay on for ages! Once you've been trained in the health & safety, contraindications and been shown the basic method of application, the rest is just practice, practice, practice! It's a really popular treatment, in my salon we used to promote it loads and got clients in for other treatments off the back of it. Clients love this treatment I would definately say it's well worth doing. Good luck! xx
