1 doctor agrees

In brief: Silica

Is the first one i think of.
Calcium can be another. There is a supplement called horsetail or hair, skin, and nails that is very helpful for many. See if that helps over three months...If not see your doctor. There is a great micronutrient test called spectracell (www.Spectracell.Com) that may also be helpful to you.
