Can I expect miracles!
'My nails are recovering from having Gel Nails so I am hoping that I am going to see a difference on using the Nail Envy and the Nail Strengthen. I suppose I can't expect miracles. I can't blame the Gel Nails. My nails have been thin but also break easily . I have trouble with my hair as well as it is getting very thin. I am also taking a supplements to help this.Hence my purchase! I am looking to OPI'S product to help me with my nails at least.

Phenomi-nail!
I noticed a difference from the first application. I was religious in my application and finally my nails are so much healthier, stronger and smoother. I always had ridged, peeling or split nails. Now I hardly ever get this, and if I do it’s because it’s been a while since I last applied this product. It’s great and works a treat for me.

Nails much stronger and longer now
I don’t usually give feedback, especially positive feedback …. But OPI nail strengthener has stopped my nails breaking down the sides, and splitting, and they are growing much stronger than ever before. Wish I had discovered it sooner.. a miracle! Thank you OPI.
