Very good to strengthen nails
Great product.I have used this before and it makes your nails much stronger.I used to bite my nails for years and now I don't anymore.But this product makes my ugly nails look better and cooler. Any Sally Hansen nail product is a sure winner! Your nails also look shiny after you apply this so they look classier too.

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.
