ProStrong ProAdvanced Fluoride Nail Strengthener, 1 fl oz is rated 4.1 out of 5 by 10.
Rated 1 out of 5 by from Created more of a problem I have been using this for six weeks and I purchased it as I had one nail that had begun to peel. Now they are ALL peeling. I wish I had the success that most all of you seem to have had. Too late to return, just glad it was not really expensive!

Rated 5 out of 5 by from Best stuff ever Love this strengthener, I don't like to run out of it.I keep my nails natural and short, have to wash hands a lot for work, keeps nails from being brittle. Love that I can use with polish if I want to.

Rated 5 out of 5 by from Works! I had acrylic on three nails to keep them from breaking but when I took it off, my nails were destroyed. It's taking time but I do see a difference. Hopefully, in a few months, my nails will be back to normal. I don't think I would have these results without using this product.

Rated 5 out of 5 by from Magical I started using this product a few weeks ago and I am amazed at the results. I do a lot of gardening and I am very rough on my hands but this is saving my nails. My main problem was peeling and even the nails that did peel and have indentations in them are strong and not breaking. I just ordered another bottle because I never want to be without it.

Rated 1 out of 5 by from Made my nails peel I have always had fairly strong nails, but I thought I'd give this a try to see if it would help stop them from tearing on the sides when they get longer. Not only did it not help with that problem, but it created a totally new one. My nails began splitting into layers and peeling so badly that I had to cut them almost to the quick to eliminate the problem. I like the other ProStrong products, but I'll avoid this one from now on.

Rated 4 out of 5 by from Excellent I bought this product along with the ProStrong calcium at the advice of one reviewer. I had put on the LCN gel tips after having them off for a long time. Ladies, I will NEVER put this junk on my nails again. The damage was so bad I was embarrassed for anyone to see my nails. I started using this as one reviewer recommended, I would apply the fluoride then the calcium then the fluoride again. It sounds like a bit much but honestly it takes less than a minute to do so. Then I applied a cuticle oil and rubbed it in. The products can leave a bit of a residue and the oil is just good for then nail. I used OPI Now the results, for anyone who has done this to their nails you will understand what I am going to say. There is an indentation where the nails are filed every 2 weeks or so. This is what I call "rotten" nail. It takes time for this to grow out. I have been using these products since about the second week in June. My nails look much healthier and the rotten nail is making its way to the tip so soon it will all be healthy. I have used these LCN gel tips many times over the years and it has taken much longer for them to grow out. I have no doubt using these products have helped speed things along.

Rated 5 out of 5 by from Really works... Had used this Pro Strong product a few years ago...then ran out. Recently found a bottle I had misplaced and started using it...made a big change in my nails. They were always breaking and I didn't have the nails I really wanted. Saw QVC had this Flouride Nail Strengthener and immediately purchased the 1 oz bottle. Now I'm back on track...my nails are strong and long and I am a happy lady. Even bought several bottles of polish to make my pretty nails, prettier!!

Rated 5 out of 5 by from this really works I have used this Fluoride Nail Strengthener for a long time. The first time I used it I was amazed at the improvement it made in my nails in such a short time. I now use it about every two weeks when I redo my polish. It is a very easy to use and keeps my nails in tip-top condition.
