ProStrong Advanced Fluoride Strengthener Duo is rated 4.3 out of 5 by 46.
Rated 5 out of 5 by from First Aid for Nails Since high school I have always used nail polish. I started this back in high school since this was one thing we were allowed to do in private school. My nails have always looked nice although in the past few years I have noticed that they are yellow and breaking easily. When I purchased the Pro Strong the notice said not to expect changes for a month. Well I noticed improvement after only a week. The yellow is gone and my nails are stronger. I would recommend this product to anyone having issues. I use it twice daily right over my nail polish.

Rated 5 out of 5 by from Best products out there I have used pro strong products for years. I cannot say enough good about their products. My nails were not good, some years ago saw this line, ordered them and within two weeks my nails were completely changed. I use this product as base, top coat, I use their polish in pale pink and ivory, do a French nail, it wears well,. QVC does not promote this product, however I can still order this from them and can also,order direct from company.. Overall the best product I have found for my nails.

Rated 1 out of 5 by from Didn't work for me After using this for over a month and applying it at least twice a day, my nails are no healthier than when I started. They continue to break in spite of using this consistently and regularly. I had hoped this would be the miracle cure for having nice nails, but it didn't happen for me, which is unfortunate because I'm the typical female who would like to have nice nails without having to go to the salon for artificial ones! I'm very disappointed in this product... It would be nice if QVC had a longer return policy on this product as we the consumers need sufficient time to find out if it is going to work or not... Thirty days is not enough time to use this product to determine the product's effectiveness.

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.
