Works
I used as a base, kept on for a week. Took off the color and base & I felt my nails are stinger feeling. My nails always tear and snag- drives me nuts. I am now 3 days in on using this daily, no peeling, no problems, nails feel thicker.

Very Disappointed
Very disappointed in this product from OPI. It chips the second day after applying 2 coats. The directions say to apply 2 coats, then an additional coat daily. I only applied 3 coats total because if I applied a coat daily for a week I would have 9 coats on my nail. It is difficult to remove the 3 coats and my nails break off as the strengthened wears off. Why no other reviews?

Does not work and peels off nails
I wanted to love this, but after one day or three days, the polish peels off from the tips, from the beds. I have reapplied several times to clean nails with the same result. I am going to throw it out.

Best strengthened for my nails!
My go to as a base coat alone or under polish! I have very oily nail beds and this is the first product that I’ve found to help strengthen my nails. I just started to use color polish and have found that it keeps my nails looking great!

Even Better than Nail Envy
I bought the OPI Natural Nail Strengthener a few weeks ago and I love it. I have used Nail Envy before, and while it worked well to help strengthen my nails, I ended up not liking the tinted colors. After a few days, they would dull and would show growth, so I would have to remove it and reapply. The clear nail strengthener is so much better for my needs. It leaves a shine on the nails after applying and does not become dull or flat. New growth is also less obvious because it is clear. I just reapply another coat. It has definitely helped my nails to grow & strengthen. My next most favorite benefit is how pretty my fingernails look. Even though it is clear, my nails look better with it on. My nails are healthy and the nail strengthener gives them the finished look of having a French manicure without having had any manicure at all. I would definitely recommend.
