Really works to strengthen and help nails from peeling. I am impressed.
This product has stopped my nails from peeling, it has made them strong and I am now seeing length occur. I apply this nightly before bed. Did that for 3 weeks, and then just now started using an all in one nail strengthener color polish. And I still apply this bond repair to the undersides of my nails. I am excited to see how long I can get my nails next. I think this product works wonders and I highly recommend it.

Excellent product
I'm on my third bottle of this - it really works! My nails had become brittle, were splitting, chipping, and breaking. Apply the product, let it soak in or massage it in. I wait ten or 15 minutes before then applying a clear polish. My nails have gotten so much stronger - highly recommend this product.

This is the real deal!
Easy to use every day, and it really truly works. My nails have been completely transformed. You won't be wasting money with this product because the results are noticeable even after using for 1 week straight.

My nails are so weak from gel polish. This does help strengthen the nails.

Nail Repair
I’m going to start with 3 stars and may update over time. It’s a costly product. If it works, then it will be worth it. The bottle was plastic wrapped, meaning no way for any contents to spill in transit. However as others have said, there is not much product in the bottle. Since the bottle is white it’s not like you can see that. I had to angle in with a light to see that there is very little in this bottle. The reason I questioned what was inside is because it’s nearly dry on the brush when it comes out. I had to apply multiple coats tipping the bottle each time. Also it says for use with nail polish on the description here on this listing. But on the bottle says to use under. Yet to also use once a day to a bare nail. I got this so that I could apply first, do my base coat, do my polish and use on top until time to repaint my nails. Using daily on bare nails will only work for people that don’t polish. I hide my damaged nails under polish. So time will tell. Not sure I’ll buy again since the bottle isn’t full and very dry when it does come out.

This stuff really worked for me
I wish I had taken a “before” picture to post. My nails were splitting and breaking and all I could do was keep them super short and filed down. I tried this treatment with low expectations, but I am truly amazed by how well this product has worked for me. Even after three applications there was a big difference. Now, after epseveral weels, my nails are growing in without splitting and breaking and look so much better. I don’t know how or why this works, but I am very impressed.

I Finally Have Nails!!
This nail treatment has really worked!! I have had trouble getting my nails to grow even close to the end of my fingertips for all 73-years of my life! I have tried alllll kinds of treatments, polishes, pills, etc over the years but none of them did for my nails what this nail treatment has done!!! The only draw back is, if I understand the directions correctly, I can't use any colored polish - at least not for very long. The bottle says to "apply daily to bare nail" so once you polish the nails, they are no longer 'bare' for the treatment to work on them. But, for a special occasion, I would polish them, remove the polish after a day or so and then go back to the treatment on bare nails. BUT, at least I finally have nails!!! One reviewer said they couldn't see the product in the opaque bottle & thought it must not have much in it but I have been using the treatment daily since purchasing in early September and it is now almost December 1 but I haven't run out yet. After accidentally tapping a hard surface with a nail, I have had a couple break over these months. In those instances, I put the product on the bottom side of the broken nail to help strengthen it as it grew out and it matched the other nail lengths again in no time.
