My daughter went through this when she was six. After her eyebrow fell out, her fingernails started to become deformed. We went to the dermatologist and he put her on prednisone and nothing happened. We moved to Tennessee about this time and they require a complete physical before children from out of state can attend school. Her bloodwork showed that she was Anemic. Started her on iron pills and her nails and eyebrows came back within a matter of just a few weeks. The doctors poo:-pood the idea but it has worked over and over for my daughter, grandson and friends that have tried it. You can have her tested or try tnis for a couple weeks and see what happens.
