About ProStrong® Nail Care

ProStrong Technology
ProStrong is a patented fluoride technology. They discovered that fluoride can help strengthen the nail, and ProStrong's nail strengthening formula with twice the fluoride helps strengthen nails. One month after the fluoride nail treatment, it takes twice the force to bend the nail as it did before. ProStrong can help soft, weak, splitting, peeling, and acrylic-damaged nails appear more beautiful.

Why ProStrong Products Work
ProStrong's patented nail strengthening and moisturizing formulas contain fluoride, or liposomes that help strengthen and moisturize nails—leaving you with strong, beautiful nails that hold up to the rigors of everyday life. ProStrong products do NOT contain formaldehyde, toluene, or dibutyl phthalate that can be damaging to nails over time.

Rated 4.2 out of 5 by 20 reviewers.
Rated 5 out of 5 by GREAT! I love these. Other nail files split my nails but these do not. I'm a guy and i just want to smooth my nails - no frills. These do the job and gave a nice buffing. I recommend these. 12-27-14
Rated 4 out of 5 by What happened to the old one? You used to carry a little four sided file by ProStrong. It was on a small rectangular block with four different textures. Loved that one and it did so much to keep my nails a smooth. I wish we could still get that one. However, this set of 4 is nice, just not as good as the old one. 08-06-14
Rated 5 out of 5 by Saved my nails The best nail file ever! These files saved my nails. I noticed that when I treated myself to a manicure my nails would start splitting and breaking within a few days...and it was from the rough files they use. So I ordered these files from ProStrong and the I noticed a difference right away. Now whenever I get a manicure I bring my nail file with me. I won't be without these files. 05-09-14
Rated 5 out of 5 by Best files ever I've been using these nail files for years. I would not use over the counter nail files even if they gave them for free. These are the only files I use on my nails!!! Best ever on the market, please never stop making these!!! 03-18-14
Rated 5 out of 5 by Hurrah, QVC still has these!!!! I have used these nail files for several years. They are great and last a long time! Thank you QVC for still carrying this product. 11-18-12
Rated 5 out of 5 by The Best! These are positively, hands down, the best nail files. I have been using them, and giving as gifts, since the Q has carried them. 06-25-12
Rated 1 out of 5 by What Happened??? I, too, have purchased these files for years. My last shipment (2 sets) were just as the last reviewer said: the pink side was no longer very, very fine and smooth. This was key to the special nature of the product (and touted in presentations): the superfine side finished off the filing leaving no snags, etc. I don't know if the change was intentional (or a manufacturing defect), but I will not purchase again until I know the original quality is back. 10-09-11
Rated 1 out of 5 by They've changed for the worse! I wrote a stellar review on these before I got my most recent shipment...big mistake! These USED to be the best files ever....Not any more. The pink "smooth" side is no longer smooth. It is very rough and no longer gentle enough for my delicate nails. I want to cry. Apparently Prostrong either got a better deal from another manufacturer or decided just to cheapen their files...either way bad idea. I won't continue to pay for these expensive files. Prostrong, if you ever read your product reviews I hope you read this and take heed. Please, PLEASE bring back the original files. 07-29-11
