Hi. I m having a major problem with soft fingernails and hair loss. It s been over 2 yrs. since I stopped getting French tips and my nails continue to grow only a little before splitting at the edges and I have to cut them and being so soft and flexible that the top part of the nail begins to peel. I have had an increase in hair loss over the past yr. also and wonder if it s related. I ve had my thyroid checked several times over the last 2 yrs. and have diabetes 2 so I carefully watch what I eat to make sure I m getting enough nutrients,Esp. cacium, magnisium and potassium among other things. I also take a Centrum multivitamin/multimineral and Mega red krill oil daily. My Dr. has me on 5000 IU of Vit D daily along with my other meds. I ve tried adding extra calcium and biotin to my diet without any improvement. Could it be another vitamin deficiency???
