Scientifique K Plus Nail Hardener, 5 ml

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.

I’m genuinely impressed with the results! Within just a couple of weeks, I noticed a significant improvement in the strength and resilience of my nails. They used to be quite brittle, but now they feel a lot more durable and healthy. Good after having my nails damage by gel. The application is super easy, and the product absorbs quickly without leaving any sticky residue. Overall, I’d highly recommend it to anyone looking to improve their nail health. Five stars!

Have used this for years. It’s good stuff, but of course has to be used forever basically. Delivered quickly especially so given the Christmas rush.

I don’t usually write reviews as I’m just too busy but wow I had to come and write this one!! Following 3 consecutive shellac manicures my nails were totally ruined - fragile, dry and splitting at the ends and breaking non stop. I was recommended to a very good manicurist who recommended this product - used it for a week (applied it 3 times that week) and my nails are the strongest they have been in a really very long time! Blown away!!!

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.

I haven’t seen any effect as I am using nearly 4 weeks. :(

I almost destroyed my nails using gel polish. Using this as well as the Mavala cuticle oil has made such a difference. My nails will not completely heal but using this will protect them while the damage grows out. Highly recommended.

This product actually works used it for years

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 :)
