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.

My nails were very weak after acrylics and its been two weeks and this has helped them grow while avoiding damage. It helps harden the nail a bit to prevent bending or chipping from their weakness! Love it!

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
