1 Protect your hands when it's cold outside to keep your nails from getting brittle and give them the chance to grow long.  Get plenty of sun, even in the winter, since the sun helps your body create the vitamin D your nails need to grow faster.
Vitamin B-12 of the B vitamin complex strengthens nail growth; therefore, a deficiency in B vitamins may cause fingernail ridges. Iron deficiency causes ridges in the fingernails usually accompanied with white spots; Koilonychia is a condition associated with iron deficiency.
