naturally long and strong
I use all the Nail Envy colors. Never in my life (50’s)have my nails been this long and naturally strong. I’ve been using nail envy for about 6months. It’s incredible, i actually have to cut them shorter. I am so impressed and happy. The tech at the nail salon told me to not comeback for gel because my nails were too thin. Now I’m saving my money and never going back. I LOVE NAIL ENVY!

Poor Quality from Good Brand
This is quite possibly the worst bottle of polish I've ever bought from the OPI brand. It leaves streaks and chips easily (within 24 hours). The instructions say to apply 2 coats the first day, then on days 2-7 apply an additional coat, but the first 2 coats are ugly (streaked) and start chipping within hours. I'd return it if I could, but it was final sale (at $15!!).

LOVE!
My nails had become weak after years of dip polish when I normally have very strong and thick nails. I have been using this for about a month now and I have noticed a HUGE difference. I do as it instructs and add a coat everyday for about 3-4 days before I remove and reapply. I feel I am about ready to not have to use anymore, they are already so thick and long! Idk why there are bad reviews because this product truly works!! (Only negative is the light pink I have can look a little streaky but I don't mind as it is strengthening!)

They ruined it!
I used to swear by Nail Envy, the older formula. Two coats of NE, two coats of color, and a top coat and my nails would last two weeks! My natural nails would grow so long that people didn't believe they were my real nails. Not anymore. My nails chip within one day. And now, I'm noticing my nails are peeling, which means lots of breakage and short nails. SO DISAPPOINTING. I was a very loyal OPI customer. I have tonssss of colors. But this new formula pales in comparison to the old one. BRING IT BACK!!!
