I'm now taking large daily doses of biotin and calcium supplements to try to counteract some of the damage wrought on my nails from estrogen. If that doesn't work after a few weeks I'm going acrylic. Janet's right- if done carefully they won't damage your nails which is what my sister told me as well and she's had them for a long time off and on. Besides, it can't be any worse than constantly breaking, splitting, or delaminating them the instant they get any length beyond your fingertips.
