I use this as my normal base coat every time I do a mani. I've been using this since February of 2012 and my nails have definitely improved since then!

Prior to using this product my nails would always break. Now they are strong. I need to keep using the product in order to keep my nails nice. Dries within 5 minutes and leaves a very nice shine.

Of course OPI is a higher-end brand so it is a little mroe expensive but its totally worth the price. I have been trying o grow my nails for some time now, but they kept breaking off because they were so thing. I've been using this for 4 months, putting it on as a base coat before my polish and my nails are so hard now. I love this product.

I love OPI nail envy! on more than one occasion it has literally saved my nails from being a broken peeling mess to being as hard as a rock!

my nails are always peeling, so i was recommended the nail envy by a co-worker. I just love that i can put it on my nails under my regular polish and it while it helps strengthen my nails. My polised stayed on longer too. I love that it comes in matte and regular(shiny). so that you can wear it alone and still have that polished manicure look. It also isnt thick, which i find with some other nail strengtheners i have used in the past
