Splitting nails

I'm so upset. My nails are weak and splitting. I know it is related to the alopecia. I hate it. It is the painful part of this disease. The hair fallout is just annoying, but when your nails split, the protection that was once there is now gone. Right now only the index finger of my right hand doesn't have any cracks on it. I'm grateful because I use that one the most. The other ones I put hardener on so that there is some protection.
