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

Nail strengthener
Not sure if I have given this enough time to work as my nails haven’t improved yet. However they were in really bad condition so I’ll keep using it until they have grown up the length of the nail bed to see what the new nail is like.

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!!

Don’t waste your money
Did nothing to improve my nails. Flakes off easily or chips taking the tip of your nail with it. Went straight into the bin.
