Here are 5 Foods for perfect nails
If you have dry nails: Eat fat
Essential fatty acids found in fatty fish, chia, and flax seeds may moisturize nail beds.

If you want harder nails: Eat protein
Consume at least 6 ounces of high quality protein daily like eggs, chicken, and fish.

If you have dull nails: Eat iron-packed foods
Fill your plate with dark green leafy vegetables, beans, and eggs for a boost of iron.

If you have vertical ridges: Eat Magnesium
Grab a handful of almonds daily for a good source of magnesium to help prevent ridges in nails.

If you have weak nails: Eat Biotin
Eggs contain a good source of biotin which plays a role in the development of keratin, a nail strengthener.
