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

This works better than anything else! This is not a polish. You need to Apply to clean, dry nails so the nails absorb the keratin. It takes 1 minute to dry. I have been using 3x a week and my nails have never been so healthy. I used to wear opi powder and gel nails, so my nails were wrecked when I began using this product. I do a lot with my hands, clean, create, scrub, garden. My nails have become so strong. I have tried everything and this is the best, worth every penny. Follow directions only apply to end of nail, moisturize cuticle with cream or oil for best results!! This is not sponsored.

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 have actually known about this product for about 30 years. I was introduced to it by a friend that worked in a salvage yard and had damage his thumb nail an this product helped repair it in just months.. if you have thin nails or use a lot of false, acrylic, or gel nails and your bed is damaged, you only need to use this product a few times to have strong healthy nails.. my only word of caution is this is like pure keratin so if you use to much your nail will become like glass and break easily. use it maybe once every two weeks till your nails are strong then stop for a few months.

My nails are soft due to gel and powder use, but this helps. I can now grow them out about ⅛-½" and they look great. At first, I used the strengthener about every other day. They grew long and started breaking off - so I backed off to about once each week. That sure does it for me! Then I put on a couple of coats of Londontown "Illuminating Nail Concealer," and I'm good to go!

Indiscutiblemente si algo puedo recomendar es este fortalecedor, endurece las uñas desde el primer uso, si lo usa continuamente ves un cambio radical en tus uñas crecen sanas y fuertes de una manera rapida, nunca habia probado algo similar, esto es único vale cada centavo en lo absoluto.

I was looking into items to rebuild my nail strength and saw this one recommended. I ordered it and tried it for a few days and had constant cracking and breaking. It's only just started recovering since I stopped. It may have just not worked well for me but I wouldn't recommend this.

Didn’t do anything for my nails. Didn’t see a difference

My nails are typically thin and break easily due to thyroid disease. Ended up getting powder gel coating because it was the only way to keep nails. Bought this with a skeptic mindset because all over products gave me meh results, but the moment the acrylic was off my nails were awful. I’ve been using this for a month and I’m amazed and very pleased with the treatment. My nails are naked (no polish) and strong as when I have acrylic powder coating. My friends are amazed by my results as well as myself of course. It’s a nail miracle in a bottle!!!! Definitely worth every penny—buy it!

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

Se você tem unhas que escamam, quebram com facilidade ou frágeis, esse é o melhor tratamento. Ao colocá-lo nas unhas, depois de seco, não fica nenhum brilho, cheiro ou cor. As unhas absorvem o produto. É indicado usá-lo de 2 a 3 vezes por semana, bastando apenas tomar cuidado para não passar perto das cutículas, pois elas irão endurecer. É um excelente produto. O melhor que há nesse segmento.

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).

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 :)

Bester nagelhärter, kaufe ich immer wieder Aber Vorsicht es ist kein Lack ! Klare Flüssigkeit die in den Nagel einzieht
