No, but I have this thing that is Sally Hansen Miracle Growth or something and it moisturizes your nails and makes them grow longer faster.
i would recommend u don't because when u take it off it will hurt your split nail and perhaps rip it off so please don't for your safety
Can make the nail brittle and chalky looking. I don't personally recommend doing it unless you are gonna use a clear coat afterwards. Even then your nails will look funny.
The nail will be full of rust (reddish orange color) in 30 days (one month)
nail polish contains chemicals which sublimate and pollute the atmospere
