Mavala Scientifique K Plus Nail Hardener, 5 ml

Fabulous for nails that keep breaking. After using this my nails are really strong and no longer break.

I absolutely love this nail treatment! It strengthens my nails, makes them look healthier, and helps prevent breakage. After using it regularly, my nails feel stronger and grow faster. Truly a must-have for beautiful nails!

Definitely the best nail hardner on the market. It’s a blue tinged liquid you apply to nail tips only, not the consistency of nail polish but it does the job perfectly.

I cannot use nail polish or any nail hardener that is a polish. This soaks in the nail and helps strengthen it. It works

This nail product, showing great results in two weeks!!

Have been using every couple of days for the last month. Not a dramatic improvement but OK

Does what it says. My nails are much stronger and now not splitting

Healed the vertical split in my nail!!! I use this as my first coat under my base coat. The bottle is tiny, but it will last forever because it’s very liquid and easy to apply. I cannot believe the split, that I have had for YEARS and tried everything on, is literally fused back together. This product seems expensive, but it is a miracle in a bottle!! Get it and be amazed! Thank you Mavala!!!
