MAVALAScientifique K Plus Nail Hardener, 5 ml

I wish I took a before picture of my nails to show the difference in just use of two weeks (re-apply every 3 days) - my nails layer and peel, be transparent in areas and very prone to breaking. Since using the strengthener they have become solid, healthy looking and strong! I did break one of my thumb nails and let me tell you - the nail itself was so strong that I had to end up cutting the break off because it wouldn't go by itself. Even since the break (1 week) the nail is already growing back at fast pace. I absolutely recommend this product but use it as and when rather than daily, for my nails I found every 3 days keeps them at the right strength and good growing pace.

Prompt service ! Delivery was as Stated.

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 got this product when I was 17 yrs old due to nail biting and flimsy rubbish nails and it was so amazing for nail hardening and nail growth. I recently found the empty bottle in an old bag I had stashed away all those yrs ago, I am now in my 60’s.I looked on Amazon and was amazed it’s still available and have ordered a couple bottles for me and for my family to try.It’s an amazing product from memory and probably why it’s still available all these years later.Update; I’ve been using it for about a year now and apply it to the tips of my nails every now and again. They grow strong and long. I’ve always been a nail biter but this has worked brilliantly giving me lovely strong nails I’m proud of.Only downside is it’s doubled in price recently.

hardner for nails

The nail repair product is not miraculous, but it definitely helps after removing nail extensions. It’s effective in restoring nails, though it feels quite sticky and thick."

Excellent productUsed it for years

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!!!
