Nutra Nail 5 to 7 Day Growth Treatment - Fast Keratin Nail Hardener & Nail Strengthener for Thin Nails, Brittle & Damaged (0.47 Fl Oz)

Amazing! My fingernails were brittle & cracking really bad. My middle fingernail was ripped down to the skin after accidentally tearing it off.See my pictures, this is 1 week apart. I apologize for the first picture, it’s a little blurry but you get the point. My nails are now really strong and aren’t cracking at the base on my nail like they normally do.

girl you best believe this is a favorite of mine. bought a bottle for my mom, my best friend, and 2 or 3 times for myself. it lasts long, it keeps my nails strong, it has the prettiest shine out of any clear nailpolish i've ever tried. i feel like it actually helps the health of my nails too because they are harder/peel less when i use this consistently.

I've been using this for years and it does indeed make your nails grow and I noticed within a weekly nails grew longer but I just wish they would help them be harder and stronger! My bails are thin and break easily from the damage of wearing acrylics for years! I've tried all kinds of nail products to make the nails bed hard but with no luck!

I just purchased this recently so I will give the 7 -14 days to see changes but so far my nails feel harder. I remember this product years ago but back then it was a clear polish and worked very fast to grow and strengthen nails. This one is more water based so I will see if it gives the same results like the formula years ago.

This is the best nail product I have ever used. I noticed a difference after the first application. After using it twice a day for five days, my nails are already remarkably stronger. I will be a repeat customer.

Not what I was really looking for,, not as expected??

I received my replacement bottle of Nutra 5-7 Nail Growth. I love this product. It really works. Amazon took care of the replacement bottle right away. Thank you! Amazon is awesome!

Great product, my wife loves it. A bit pricey.
