What is the best product that makes your natural nail harder?
I already got my iron and vitamins checked so I'm good there.
Unfortunately my nails are still very thin. After biting them for years I finally got them to grow out but I can literally fold them down to a 90 degree angle.
I'm looking for something that will actually make my natural nail harder.
Has anyone tried multiple of these and which one works best?
I hate having to remove nail polish so I was hoping for something I don't have to remove to reapply.
