It's a sign of HCL deficiency. Iron-deficiency anemia may cause the nails to appear pale and become thin, brittle, ridged. Use a good cuticle oil to keep the nails hydrated. Vitamin E, prenatal vitamins, and a good multi-vitamin will help you grow long, strong, healthy nails. Nails problem!...!eh.? ?
