I have this too on my big toe from dropping a skid on my foot about 7wks ago.It has started growing out half way so at least it's getting to the end; I'm a little scared about what's going to happen when it gets there tho

Like will half the nail fall/peel off? I know the dead blood underneath it has to go somewhere.Should i put nail polish on it to keep it strengthened or will that weaken it?
