Had artificial nails for years, but with the recession, I had to have my nails removed. Tried many products and this one seems to work well. My only problem is that sometimes it makes my nails seem a little yellow.

I have been using this product for a year and my nails always look great despite my active lifestyle. I also purchased a bottle as a gift for a friend who just recently stopped the bad habit of nail-biting - to inspire her to keep her new nails beautiful!

Been using OPI for years for its durability & color. Gave this a try after getting over the price & it was well worth it!!! Been trying to find something to strengthen my weak, thin nails, that bend easily. I could never grow 'em & constant pounding on keyboards, gardening, painting & ignoring them never helped. This stuff dries VERY fast, stays on forever, if it chips (which I can't see...) I don't notice since its not super shiny (more of a just buffed look), got rid of my ridges, made them a bit whiter, & after 1 week I noticed a difference. Works well as a base, & took me a bit to get a hang of the very big brush (I have teeny nails). Its been several months now & I have these thick healthy nails -- sooo happy!

After removing acrylic nails that I had worn for years, my nails were like paper. I thought they were hopeless. A friend said she had heard that Nail Envy might work. Wow! In a couple of weeks my nails were fantastic. I use it regularly. My nails have never looked so good!

My two daughters and I have tried virtually every product on the market to strength our nails. This is the only one that really works for all of us. We even take it to the nail salon and have them apply it as the base coat. For the first time in my life I consistently have nice looking nails.

Used to have acrylic nails, but my nails were dying. This product was recommended - never thought it would work. I have never had to cut my nails before as they are soft and bend and break once there is any length. OPI strengthens my nails and they always look great. I have even had people comment on how nice they look. Great product!

I apply 2 coats of this wonderful product to clean nails after filing, shaping and buffing. After that, I apply a single coat every other day. It has saved my nails after I had really bitten them down; they are very strong and the tips are nice and white. I don't wear my nails very long, but, they grow very fast with this product. Highly recommended.

I followed the directions, applied 2 coats, then 1 additional coat daily. I can definitely see that the nails are longer. My ends were always splitting, This seals the ends and is allowing them to grow. It has taken 2 weeks already but at least I know it's working.

I do my own manicure and pedicure every week, but with this product I had to redo my manicure in within 5 days because it started peeling my polish.I bought this product thinking it will prevent my nails from peeling, but didn't work for me. I'm stickig to my tried and loved: Double Duty Strengthening Base and Top Coat by Sally Hansen, I do a lot of housework and with this producr my nails look fantastic

I've used this for 10 years. When I started, I had long, fast-growing natural nails, but couldn't keep them from breaking or peeling. This fixed it and actually gave me a French manicure look that everyone loved when worn alone and is the best base coat I've found for use under color. Now I keep my nails very short, but still use this to keep them looking manicured. It dries fast, so I can reapply day after day, if I want to freshen the look. Best stuff ever.
