    • It's a miracle.
I started using this in desperation. For as long as I can remember, I have had a deep groove on my left thumb nail that caused the nail to constantly split. As I got older my nails became thin and more prone to breaking. In my research, I ran across this product on Amazon and did some reading on other sites and decided to give it a try. Unbelievable results ... everything I read said my nails would grow fast ... no lie, I was trimming them two or three time a week. It stopped the splitting on my thumb and now the deep groove is completely gone. My wife was amazed and started using it. She once crushed a finger tip in a cash register and ever since has had two nails growing on one finger ... ugly. Now ... one solid nail !!! We now treat our nails at the first sign of any problem. Well worth it, no matter the cost. ... show more

    • So Surprised!
I have been so surprised at how awesome this product has been. I am on my second order of it. My fingernails were so sad before I started using it. They were chipping, peeling, and splitting constantly. Using this product, along with wearing cotton lined rubber gloves when cleaning or washing dishes, has saved them. ... show more

    • Leaks. Ran dry in under 2 weeks.
Couldn't test if the claims that this product improved nails in as little as a month, as it ran dry in less than half that time. It was only turned tip down when in use. It was certainly never stored in that position. At first, it was stored laying on it's side on my bedside tray between uses. It did not leak while the cap was closed, but I quickly became concerned that product was being wasted when so much poured out the moment I removed the cap. I switched to storing it tip facing up in a small pencil box. After the change, no product poured out just by removing the cap. The instructions tell you to pump once for EACH nail. I never had to pump more once for ALL of them, and often there was still more than my nails could even absorb. For the first week. After that, there was considerably less. It has now been less than 2 weeks it and it is completely dry. It might be a good product in poor packaging?? Couldn't use it long enough to find out. It is of course possible I just got a dud. But I'm not willing to shell out another $29 to find out. Very disappointing. ... show more

    • Saved My Ridged, Brittle, Aged Nails
This product is stunningly effective. I'm a woman in my late 60's; never wore finger nail polish, always had strong, long healthy nails. My nails have become quite ridged & brittle in recent years. They broke at the ridges, and I could no longer achieve long nails. Worst, my thumb nails would split along a ridge, 2/3 down the length of each thumb. I have used SI-NAILS for about 6 months now. I apply it once a day, before bedtime (and moisturize my nails like made, with Cera-Ve, during the day). The improvement is marked & I am quite pleased. I have NOT regained the nails I used to have. I can grow them modestly; they break at the ridges still, all the time. And my thumb nails remain problematic and a bit ravaged. But overall, my nails are astoundingly better. ... show more

This stuff was literally an answer to prayer! HIGHLY RECOMMEND! I had been struggling with thin, peeling nails for over a year. I had back-to-back surgeries and my dermatologist told me my damaged nails were probably a result of the anesthesia. (I've never done regular manicures and very rarely polish or gel, so I couldn't blame that.) My nails were so thin they hurt and they would continually split and peel no matter how much I used nail strengthening treatments or polishes. I was at my wits end and tried ordering ISDIN as a last resort. I thought it was a little expensive at the time, but now I believe it was worth every penny! I keep an extra tube on hand now so I never run out. The product and brush are so easy to use. In the beginning I applied it twice a day but tried to keep using it at least once a day for two months. Now that my nails have improved I use it about every 1-2 days. The product is easy to apply and dries and disappears very quickly. I was worried it would be messy and sticky but it is not at all. Sometimes it takes one click per nail to get it going, but sometimes one click will treat a few fingers. A little goes a long way and you will get the feel of it. The product does take time to work. It was 2 months before I had a complete nail grow out without peeling. They are strong now but I am still careful to not use my nails as "tools" so that I don't break them. I still have a split on my thumbnail but I believe it will grow out as long as I am careful and keep applying the product every few days. I will say my nails are a little "ridged" and I don't know if that's just my nails or a result of the product, but it is a small price to pay for strong nails and I can just buff them down smooth. The photos you see are: 1. at the beginning of use, 2. after 6 weeks of using the product, and 3. at 2 1/2 months (they do grow longer but I like to keep them short) Don't hesitate! Buy this product! ... show more
