The Secret Weapon for Strong, Healthy Nails
If you're like me and have struggled with weak, brittle nails, then the Nail Invisible Flex Hardener is a game-changer you need in your beauty arsenal. This product promises to strengthen nails while remaining virtually undetectable, and let me tell you, it delivers on that promise. I've been using this hardener for a few weeks now, and the results speak for themselves. Not only have my nails become noticeably stronger and less prone to breakage, but they also look healthier and more polished overall. What sets this product apart is its invisible formula, which means you can wear it alone for a natural look or as a base coat under your favorite nail polish without any added bulk or texture. Application is a breeze thanks to the smooth, fast-drying formula. With just a few strokes, you can achieve a thin, even layer that provides instant reinforcement to your nails. Plus, the convenient brush applicator makes it easy to reach every corner and edge for thorough coverage.

Great for my split nails
I'm an older lady, age 64. All of my fingernails have vertical ridges on them. The dermatologist says this is a normal sign of aging but I hate it because my left middle nail splits on occasion. This product goes over the split clearly and helps to harden that area so it can grow out without snagging on everything.

Good product BUT!!!
The product came I n on scheduled date. I did clean and manicure my nails that night yo use. My nails felt strong but I noticed after a few days my nails were yellowing. I am a smoker and believe it had to do with that some how. Needless to say I haven't used the product again.

Looks like what I ordered. Performance cannot be evaluated at this time.
Did not receive it until about an hour ago so have not used it, therefore, no opinion at present.

Does not last
I used this one day, and the next day it completely peeled off my nails. Did not work for me.

Had my acrylic nails taken off after way too long keeping them on and my nails get so thin and peel away. I work with my hands so the risk of breaking them is extremely high every single day. After applying this varnish they really seem to be very resistant despite bashing them several times a day. No breaking and no peeling 👍🏻 Also arrived early which is nice Update: seems to peel when nail varnish is applied over the top.

x3 nails were breaking and put this on and it held them like superglue, but because the broken nails were too far broken I went to my usual nail shop (Nail & Spa) in East Acton... to get added assistance but made sure they added this as a bottom and top coat because i noticed added strength straight away. Thank u for this product; o)

This product is ok. It's shiney and initially feels nice on. But it chios off very easily and sometimes bobbles when applying. Could be better x
