This actually works
This nail polish strengthener is amazing. I used it in November for the first time when I had my pedicure. And went back for my pedicure on 12/15 The color stayed on the entire month My toe nails have become so strong. My nail tech that does my pedicures even commented on how strong my toe nails were and she does a lot of pedicures The color is perfect as I don't do color in the winter. I highly recommend this nail strengthener. Doesn't smell Dries in a decent amount of time

Great nail polish
Best stuff on the market!! I got dermatitis and my fingers looked awful. My nails wouldn’t grow my skin was super sensitive on my finger tips. Instantly saw results first week I’m only on week 2 and total improvement. Don’t question it buy it it’s good!

Great product, would recommend, and would buy again
This product is great, once I put it on it was really shiny, clear, and clean looking. When I pressed down on my nails before applying it, it felt weak as if it were going to break fast, but after I put it and pressed down on my nails I could definitely feel a difference because it felt much more strong and I couldn’t press down on it that much because of how strong it was. After a few days of having it my nail broke that’s why I gave 4 stars but besides that it would be 5 stars.

Best on the market, I promise!
Best clear nail polish ever! Strengthens yoyr nails. Easy application, goes on like regular nail polish. Doesn't smell weird either. Very good quality. You can make a mistake and it would magically fix it. It does bring out any color. I always recommend this product when I'm shopping at wally world. I was just being lazy and didn't feel like going there since it's packed with people for the Holidays.

Miracle indeed!
It works. My nails have never been strong despite several years of biotin. They split , break and crack. I ordered Sally Hansen Nail Treatment Miracle Cure not really expecting a big improvement. I was wrong. After one thin coat my nails looked and felt strong. Miracle indeed! I’m a believer!

Not what it use to be
I've used this before and it protected my nails and helped them grow, that was over 10 yrs ago. This didn't do anything and my nails still broke despite religious use

(Dont mind my uneven nails trust the process)
LOVE!💕 Not only is the bottle cute the product is amazing. Honest. I saw this on pinterest and my nails can grow long but they're prone to breaking easily so i got this and its my holy grail now it hardened my nails so quick i mean in under a minute and the shine effect has afterwards is cute! Its a good price and a little goes a long way! Its not thick but also not too watery easy application and its not greasy when its on! For a moment it has a regular nail polish smell but then it immediately goes away when its dries 10/10 i dont see how this isn't more popular but im glad its not lmao

Ich habe schon immer wahnsinnig weiche Nägel gehabt. Da änderte auch keine Ernährung etwas. Dieser Nagelhärter war nach nur 2 Anwendungen (ist jeweils eine Woche auf den Nägeln geblieben) ein wahres Wundermittel für mich gewesen. Er hält super toll, man kann ihn auch sehr einfach über lackieren. Die Nägel sind auf jeden Fall härter geworden, ohne auszutrocknen und dabei abzubrechen. Grandioses Produkt, riecht auch nicht allzu chemisch wie andere Härter und es ist auch sehr leicht aufzutragen.

Casi nunca escribo reseñas, pero esta vez tenía que hacerlo. Me quite yo sola las uñas de acrílico y me lleve varias capas de mis uñas, con cualquier cosa que me pegaba me dolían y se rompían, parecían papel. Me estoy poniendo en el día y noche este producto junto con el lápiz de isdn y mis uñas en cuestión de días fueron otras, no sé si es la combinación de los dos o que, pero de verdad me salvó esto. Lo aplico y masajeo en las uñas hasta que lo absorba.

Buenísimo, sí te ayuda a reparar tus uñas, yo lo he estado usando después de quitarme gelish y te ayuda a fortalecerlas, lo uso solo o como base de esmalte, el color por si solo es muy sutil y lindo.
