I am nail technician. Opi nail envy is only nail strengthener product that i use for clients. I love this product so much, i would recommend this product to any one i know. This is no scent.

I work as a nurse so the constant hand sanitizer and hand washing wreak havoc on my nails. This product strengthens my brittle nails with regular use. I also find that it is easy to remove after 7 days and doesn't dry out my nails.

With most strengtheners I only use them for a short period of time but I believe Nail Envy always helps get my nails back to a healthier stage if I need!
