Great product.
Great product helped my nails recover fully after having 4 months of acrylic nails which ruined them. This repaired and helped my nails grow delighted!

It really helped strengthen
Ok... So I messed my nails up with gels, biab and not getting them properly taken off. My nails were so thin and weak... Disaster! So scrolled through amazon and found this. I bought it. I used it as instructed pretty intensely at first, then less so after about 2 months. I'm probably 5 or so months down the line and a lot of the damage has grown out now and my nails are growing and are stronger. I think this really helped me. I could certainly feel after I applied a couple of coats that my nails felt stronger, when they were dare I could literally bend them but with this on it was stronger and gave more protection. I would recommend this to anyone suffering with nail weakness

Good
I think it’s working but it’s taking a while for the results to show

Peels often
Find it peels after couple of days so seem to be constantly applying. Seems to make no difference in my nail strength or length as of yet.

Such amazing results!!!
I’ve been bouncing between nail biting (actually ashamed of that 1st pic) and acrylics for as long as I can remember. I’ve always been super self-conscious about my hands, and no matter what I tried (every nail strengthener under the sun) my nails would just keep bending, breaking, and starting over. But honestly, the difference I’ve seen with this product is crazy. I followed the instructions and applied it consistently twice a week. Now, my nails are solid. (See 2nd pic!) They’re holding up through workouts, weightlifting, and even my physical job. I never write reviews, but I really wanted to rave about this because it actually worked. Finally!!

No results from day 1
I liked the packaging and the bottle. It applied like a gel depending on how much polish you put on the brush. It promises results from day one and stronger nails. Unfortunately in my case this was not true and it just made my already thin weak nails worse. I could not see how to contact the seller, so I am sending back to Amazon for a refund. It may work for u, but fir thatbprice and whatnot claims on the bottle I am extremely disappointed

So impressed!
Wow! I'm so impressed, even after the first application! I've tried so many nail products in the past to try & strengthen my nails but none have worked as well as this product. I'm so hopeful that in time my nails will be very hard, without any bend. Got it on subscribe now, it's so good! One very happy customer 🙂
