Review: Cumple lo q promete. Muy buen endurecedor - Es lo mejor que he probado para endurecer las uñas. Las tenía estropeadas por abusar de la manicura permanente… al principio compré otro producto en formato esmalte, tb endurecedor, pero al usarlo tal cual indicaba se me ha acabado el bote y he decidido probar con otro… Era un poco escéptica con los productos q eran líquidos al pensar q en cuanto me lavase las manos se iba a ir el producto. En este no me ocurre eso, lo uso a diario y se nota de verdad!! Estoy encantada!! No deja la uña como un esmalte en plan brillante pero lo bueno es q tal vez por eso deja respirar a la uña y es más eficaz.Ademas hay q echar muy poca cantidad y a pesar de ser un bote pequeño cunde mucho. Mavala nunca decepciona!!
Review: Melhor tratamento - 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.

## Questions & Answers

**Q: What are the ingredients?**
A: This product stinks.  Buy the diamond by Revlon

**Q: If this product costs $137.50 per fluid ounce then 1/16 ounce should only cost about $8.60. Why the great discrepancy?**
A: The algorithm is a calculation created by Amazon internally.  We do not have anything to do with why Amazon would make such a claim.  Our price per bottle has remained the same since the asin was created over 2 years ago.   Our sincere apology for any discrepancy the Amazon algorithm has placed on this page.  Thank you for your interest in the Mavala Scientifique K+ product...

**Q: Is this product cruelty  free?**
A: The instructions don't say if it is cruelty free.

**Q: Can you use this product over a gel overlay manicure?**
A: The instructions say to ensure nails are free of nail poish and any other oily film.

### ⭐⭐⭐⭐⭐ Long and strong nails in 4 months of use
*by R***E on 15 September 2024*

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).
