You may think you need to eat more gelatin or take iron supplements, but neither of these is to blame -- cracking, splitting nails typically result from repeated exposure to water over long periods of time.

If they're dry and cracking, it's going to take time and patience to repair them. Fingernails grow slowly at a rate of about 0.08 to 0.12 inches (2 to 3 millimeters) per month. Because it takes your nails three to six months to grow from cuticle to tip, you'll have to maintain treatments and preventions for a while [sources: American Academy of Dermatology, Nemours Foundation].
