MAVALA Scientifique K+ Keratin Hardener Strengthener | Protect Nails | Avoid Breaking and Splitting | Supports Natural Keratinization | Multi-color, 0.16 Fl Oz

A great product, worth its price. Does the job.

the only one that works for me. my nails have never looked better, this really works

I’m using this product 1x week for the last 3 weeks and my nails has grown a lot, despite the fact that still a bit “weak “ in the photo my nail has got much much harder, just need the consistency of removing and using 1x or 2x week. I’m using a combo of Mavala + strong start (Essie brand) and it’s being the best so far after using extensions for many years! Buy it you won’t regret itCamila Chicago IL USA

My nails are very pliable. Easy to use, just brush it on for stronger nails. I wish the bottle was larger.

I've always had soft, bendable, peeling nails, a combination of genetics and thyroid problems. I've tried just about every "nail hardener" out there, creams and gels and polishes etc. Not a single one has worked. The only thing that came close for a while was simple Bag Balm, but my nails were still noticeably weak. Nail polish at the free edge always chipped within a day of applying because my nails weren't strong enough to withstand bumping into things, and I kept my nails very short.I used the product every other day for three months as I was growing out some damage that was causing peeling. Even after the first application I could feel a difference, and it kept my nails from deteriorating further while I grew out the damage. I didn't use anything else on my nails except Bag Balm, which is what I use as a moisturizer on my hands.The pic I included is my nails at the length I prefer, and they are SO STRONG while remaining flexible. Polish lasts for at least a week even on the free edge. I only use it once or twice a week now, between polish applications.

I was hoping this would work as I was looking for a non-formalin based nail hardener, but it did nothing at all.I even applied 3 to 4 coats per nail at a time, several times a week, My nails were clean & wiped with acetone in hopes of better absorbance, but it just didnt work.Ive tried other supposed good nail hardeners without the formalin and they also didnt work for me.I had very good results with the Formalin-based nail hardeners in the past but I read formaldehyde based hardeners can be a bit toxic if you're not careful, so i tried this one in hopes I wouldnt have to get the formalin one, but nothing.I ended up getting the Original Mavala, which does have formalin, and as expected it works.

I thought this product would be more efficient, I have been using it for several weeks and I don't see that there has been an important change in my nails.

This.This is THE product. 5 years of acrylics without a break and my nails were so thin they could no longer support the acrylics.I have been using this for a single week (daily, instead of the recommended 2-3 times a week, because I ain't gonna let CAPITALISM tell me what to do). Hard as Hoof nail lotion and some nail oil on top to keep them hydrated, as some reviews said it can be drying.I don't think my natural nail has ever been stronger. I don't think I will even need acrylics with this stuff after they grow out a bit. My pinky nails are still on the fragile side but holy crap I don't think I have ever seen a beauty product deliver that fast. It's a teeny little bottle but a little bit goes a long way, I think this is gonna last a really long time. One week of use and it still looks like a completely full bottle. THIS is the product you're looking for, it is my new favorite and well worth the money.*And I don't find it drying with the cream and oil over the top, so just make sure you don't skip that and you should be fine. I think it probably would be a bit drying just by itself.
