Scientifique K Plus Nail Hardener, 5 ml

I have used this product before and I am always happy with it it sinks into nail really well it’s ideal for people with weak nails when they do a job that you can’t wear anything on nails

After using the Mavala Nail Hardener for a few weeks I had definitely noticed a difference. My nails feel healthier, stronger and I’ve experienced much less breakage compared to before. It’s very easy to use and absorbs well into the nail without leaving any sticky residue. A little goes a long way, so the bottle lasts a long time, making it great value for money. Overall, a really effective product that does what it claims; I’d highly recommend it if you’re trying to strengthen weak or brittle 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.

After removing my gel nails, my natural nails were extremely thin, weak, and prone to chipping and breaking. At first, nothing seemed to help because my nails were so damaged from the gel removal. However, once my natural nail started to grow out a little, Mavala Scientifique K+ Nail Hardener made a huge difference. This product really helped strengthen and protect my nails. I noticed that they stopped chipping and breaking as easily, and they finally had a chance to grow properly. It’s important to know that it won’t work miracles immediately after removing gel nails when the nails are paper-thin, but once your natural nail begins to recover, this product is fantastic. I only apply it once a week, which is exactly how it’s meant to be used, and I also make sure to use nail oils regularly to keep my nails hydrated. That combination worked really well for me. Now my natural nails look so healthy and strong again. I still use it once a week or every two weeks just to maintain the strength and keep my nails in good condition. I’m really happy with the results and would definitely recommend it to anyone trying to grow and strengthen their natural nails after gel removal.

This product works, it’s expensive but works when used consistently

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

I work outdoors building high ropes courses and my thumb nails constantly have cracks which don't mend. Tried all sorts of remedies with no success. This nail hardener has worked almost instantly.

I have used this product for about two years on and off, it has made a huge difference to my nails, the were soft and bendy but now are stronger
