Rated 1 out of 5 by from Didn't work at ALL I have had very thin flimsy nails my whole life and try many new products. Like all the others this did nothing even after 2 months of very consistent use. Too late to return unfortunately.

Rated 5 out of 5 by from Love IT!!! I love this product and will continue to use it as I have softer nails and they are now hard and growing quickly. This is an excellent product and so easy to apply!

Rated 5 out of 5 by from Unbelievable Results I very seldom write reviews because so few items impress me but this product is amazing. I am 63 and my nails were peeling and cracking and nothing was helping. I found a bottle of this that I had purchased a few years early and decided to give it a try. I took my bottle to work and several times a day I would put on my nails. It doesn't have an offensive smell so nobody was bothered by it. After around 6 weeks I saw a huge improvement in my nails. They are stronger and not peeling or cracking. For those of you who have had bad luck with this product I would recommend using it at least twice a day, maybe more, and give it some time.

Rated 5 out of 5 by from The Only Nail Product That Works For Me! This is THE ONLY nail strengthening product that works on my problem nails! I have the worst nails ever! They do not grow...they only split and crack...sometimes it is painful! I love this and I don't want to be without it ever again!

Rated 5 out of 5 by from You Nailed It! I had a HORRIBLE experience with gel nails that left my natural nails weak and tissue thin. I never thought I'd have healthy nails again. I tried several different products claiming to restore nails damaged by using gel nails and tips...nothing worked...until I used ProStrong products. I never had super strong nails anyway but ProStrong Floride treatment along with the Calcium treatment have strengthened my nails considerably. I'm a true believer in ProStrong and highly recommend their products. If they could help MY nails in the condition they were in, they can help yours! Please note though that I used it faithfully at least twice a day at a minimum for several weeks before I saw a dramatic change. If you can't commit to doing it long term, it may not work for you. I won't use anything else now.

Rated 5 out of 5 by from Amazing Results This product has given me Amazing results in a short period of time! I have always had weak, peeling nails. I have spent tons of money on products and nothing worked. I decided to use this the first week with no polish or nail hardener on. By the end of the week some nails had grown to the point of having a free edge extending beyond my finger tip! Shocked. The second week I used it over my Polish twice a day and I can hear my nails on my keyboard as I type. I would add this to my "desert island" make up bag!! Love it. It saved my nails.

Rated 5 out of 5 by from Awesome Product I remember seeing this product on QVC years ago but at the time I didn't need it. When I was young my nails grew very easily. After I had my children my nails became weak and would bend very easily. I remembered this product and ordered it. After two weeks I began to see a difference. I have been using this for a year and would not be without it. I use it twice a day on bare nails and over polish. For those who say it doesn't work I would give a few tips. First of all use it regularly. At least twice a day. It drys quickly so it's not an inconvenience. Second, I keep it in my purse so that I can use it at any time. It doesn't have an odor so it will not bother other people. Most importantly recognize you will always need this product. Don't use for a period of time and then stop or skip days. If you do your nails will become weak again. My nails have returned to what they were like when I was in my twenties by using this product. I am so glad I don't have to use acrylics or gels which are so damaging to the nails. I hope QVC never stops selling this product.
