I have never been a very firm believer in nail hardeners/strengtheners, and have always just defaulted to Rimmel Stronger Double Duty which works super well as a base coat. But i recently borrowed Nail Envy and was pleasantly surprised. It comes out clear, and looks almost gel like when left plain on nails. I didn't use it long enough to see if it really does strengthen nails, but when having my nails done recently I was told by the nail tech that she swears by this little goodie.
Get yours at your local Dischem for somewhere around the R200 mark (rather pricey in my opinion).
