Rated 4.3 out of 5 by 7 reviewers.
Rated 5 out of 5 by 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. 08-05-15
Rated 1 out of 5 by 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. 07-22-15
Rated 4 out of 5 by 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. 07-22-15
Rated 5 out of 5 by 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!! 05-17-15
Rated 5 out of 5 by 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. 01-27-14
Rated 5 out of 5 by Only Product that Works For Me After trying most everything on the market and having artificial nails for several years, I nearly gave up but tried this more that 12 years ago and it worked. QVC used to carry the 3 in 1 nail pens which were my favorite but stopped. They are still available from ProStrong but the shipping is too high and the price isn't as good as QVC had. So, I began using this liquid version and it works just as well but isn't as convenient. If I make sure and apply this daily before I go to bed and use OPI Avoplex nail and cuticle oil over top, my nails are strong and grow to a nice length. I keep them reasonable short because it is more comfortable for me to type, etc., but with this product, I could grow them very long if I wanted to. This is the ONLY product that has EVER worked for me so I highly recommend it. You must use it every day, though, to keep your nails strong. 10-27-13
Rated 5 out of 5 by cant live without I love this product and this with the green bottle is all i use now and i have it sitting by me when i watch tv i put it on a couple times a day and it is the ONLY thing that makes my nails grow and hard and nice, other wise i bite them and they are super soft and peely. This makes my nails so hard i dont even want to bite them. fantastic that it comes int he larger size. 08-15-13
