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

For over 2 years, my nails would peel at the ends. They'd get to the stage where they'd look like if I could just grow them for another 2-3 weeks, the peeling would end and I'd have healthy nails. Then they'd peel again. I tried the Sally Hansen stuff with nylon fibers in it, I tried nail decals, I tried all kinds of coatings to just protect them long enough to not peel. I tried Mavala as a bit of a last-ditch effort because I'd read about it somewhere. I'm on week 3 of using it every other day and all but two of my nails are completely peel free and healthy. The other two look like they should be good by next week. And, it dries in seconds. I'm beyond thrilled with this. You just need a little on the very end of the nail. Magic.

I wish I had discovered this years ago. I saw this recommended by one of my favorite YouTubers (The Salon Life). I have had extremely thin and flexible nails my entire life. I love having my nails done, but regular polish chips off within hours due to how flexible my nails are. Gel polish does great, but it tears my nails to shreds upon removal (even if done very gently - my nails are just that thin and prone to lifting). I can tell a massive difference after just one application. I know most people seem to get by with using it once every few days, but I typically apply daily, if not two coats daily. I'm also still keeping my nails short while they grow out, but I can't overstate how much of a difference this stuff makes. Soon I will be able to actually polish my nails and have it last for longer than a day. And in the interim, it's so nice to have nails that don't catch on everything due to them being covered in little stress fractures from constantly bending past the breaking point.

The trick is to trim your nails prior to using. Especially if your nails are already thin and weak. I was getting my nails done with acrylic powder for almost a year and decided to take a break from it. At first, I had similar experience from other reviewers where my nails still kept breaking even while using, and I realized it was because I was applying on the tips of my weak nails. Now since I’ve trimmed and continued to apply at least twice a week, my nails have hardened and do not break. I’ve been using this for a few months now. I believe the time it takes for your nails to recover varies from person to person. This product has definitely saved my weak nails.

I was a loyal customer of Nail Envy for years until they changed their formula and removed the formaldehyde. It’s what my nails need to stay strong. I’ve tried so many others but finally I have found a replacement! One coat is all I need. It dries matt so I use a polish over the top. Perfect

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

I’ve been using this nail strengthening for 10 days, since it was received. My nails are paper thin and spilt daily. I have seen no improvement and have followed the directions exactly as directed. I’m just very disappointed. I thought I found something that would work FINALLY. Maybe you can suggest another stronger product for me to use on my brittle nails.

Seems to help a little but my nails still split....

The strongest nail hardner I know of. A little bit goes a long way. Toxic to cuticles, so brush on with care.

I made a comment after 2 months of use and came here to correct it. Well, my nails always took a long time to grow (because I always bit them), I did stretching in Brazil, and it ruined my nail (it became as thin as paper). I bought this product and used it for 1 month and a half and my nails were weaker than before, I actually thought it wasn't working, but I kept using it. Today, 3 and a half months later I am shocked!!!!! My nails grow in 1 week, I always have to file them (otherwise they get huge and make it difficult to wash my hair, lol). They are hard (they no longer bend, they no longer break). I'm taking 1 Biotin tablet just to help with growth. I saw some Brazilian reviews, where the girls say that the Mavala bottle lasted 1 year, and despite using it every week, and having been using it for almost 4 months, now I'm buying the second bottle (I still have a little in the bottle, but I don't want to interrupt the use, until a new bottle arrives). I think it's worth it. How I use it: I remove the cuticle, wash the nail with a brush (nail) and neutral soap (top and bottom of the nail), dry well, and then apply Mavala Top Coat. I wait for it to dry and apply the polish normally. I only use it when I get my nails done (1x/week). I posted a before photo (with cell phone in hand) and an after photo (with nailsssss).

Fonctionne très bien, il est totalement invisible.

No more my nails were so bad it was the only issue on my body and I wanted nails so bad and saw that this product had some sort of positive reviews and so I thought why not try it. It has a refund with them a certain amount of time so I bought it and I put it on right away and I was using like a hairdryer on the cold setting to help dry the nails because you have to dry them with your tips facing downwards so I would paint both of my hands and then turn on the hairdryer and dry it out After a couple of days, I don’t know if I really noticed anything but the good thing is is that this isn’t like a nail polish. It doesn’t apply in a way where it leaves a residue really you really can’t see or tell anything about your nails. everything is normal about them. You don’t notice any different. It’s not nail polish or any sort of thickener or something. It has to be like taken off nothing like that so that After I used it probably every day and you can only put it on half your nail most likely because your nail might need to breathe either maybe for like so that it looks natural I don’t know, but it doesn’t really build up to the point where it’s super thick I was using it every day and you can’t even tell to this day and I’ve been using it for I think almost a month now anyways The point is is that this actually works not only arm my nails looking better. They are strong and they’re not like like thick strong in an uncomfortable way because when you have the nails, you can really sort of feel like your nail on the top of your nail and the skin but as it gets thicker, you don’t and so it almost feels like an acrylic set because they’re in such good condition now

Je suis vraiment pas déçue ! ✨ Contexte: j'ai les ongles abîmés par une dépose mal réalisée et j'utilise mes mains et ongles tous les jours au travail de façon intensive. ✨ Ça fait 1 semaine que je l'applique tous les jours (2 couches), et parfois 2 fois par jours. Au bout d'une semaine je vois et sens déjà une grande différence. Le bout de l'ongle est plus dur et résistant. Les endroits où j'avais des dédoublement s'effacent, et Le bout de l'ongle est plus blanc. Avantages du produit : est absorbé très rapidement par l'ongle, le temps que je fasse la 2ème main, la 1ere est sèche donc je peux enchaîner direct avec la 2eme couche. L'odeur est neutre. Il fonctionne sur moi. Inconvénients : rien a voir avec le produit, c'est le carton dans lequel on le reçoit qui est nul est pas adapté, l'emballage du produit était tout abîmé, c'est hyper risqué. On envoi pas ce type de colis dans un carton plat ! Je recommande, j'ai hâte de voir l'évolution sur plusieurs semaines / mois ! EDIT 05/05 : Après quelques semaines d'utilisation, je vois que mes ongles sont en bien meilleur état et plus épais et plus durs. J'ai toujours de la casse sur les ongles que je malmène le plus au travail, mais j'ai pas trop le choix , j'ai pris pour habitude d'utiliser mes ongles comme des outils ahah. Faite attention a ne pas en mettre sur votre peau car effectivement, ca va beaucoup la durcir !! Bref je continue le traitement et reviendrai donner des nouvelles petit à petit EDIT 06.07 : j'utilise toujours le produit, 2 couches tous les 4 jours environ. Mes ongles ont vraiment changé, ils sont plus beaux et résistants, le bout de l'ongle est bien plus dur et j'ai nettement moins de casse. La prochaine étape serait de reprendre les poses de VSP et de continuer ce traitement. Je continue donc de vous recommander le produit que je trouve très efficace ! 😊 EDIT 18/08 : J'utilise toujours le produit ( il semble encore plein, j'ai l'impression qu'une vie ne suffira pas a en venir a bout ahah). Environ 2 applications par semaines, je ne saurai plus m'en passer. Mes ongles sont bien plus beaux et forts qu'avant, malgré le boulot j'arrive à les maintenir en bonne santé! Donc je le recommande toujours, si vous avez les ongles abimés par des poses et déposes de vernis semi- permanent etc, vous allez les ressusciter ! EDIT 17/11/24 : Et ben sans surprise, quand j'oublie d'en mettre pendant au moins 1 semaine, mes ongles redeviennent mous et cassants .. donc le produit est toujours aussi efficace sur moi et je vois une réelle différence ! EDIT 15/06/2025: me revoilà :) plus d'un an d'essai plus tard! mon avis reste le même, ce produit fonctionne très bien sur moi, la différence est flagrante quand je fais une pause du produit, mes ongles cassent vite et poussent lentement et quand je recommence à l'utiliser, mes ongles poussent vraiment tellement plus vite et plus forts ! je n'ai toujours pas fini le flacon acheté il y a un an, achat hyper rentable, je vous le recommande toujours :)
