1. Soft nails that curl upward
Cause: Too little iron
Solution: if an iron test verifies that your iron levels are low, your doctor will usually suggest that you take 325 mg of iron sulfate three times a day.
2. White spots
Cause: An injury to the nail or insufficient zinc levels in the body.
Solution: According to Ms. Petty, you need 50 mg of zinc each day. Good sources of zinc include peas, pumpkin seeds, red meat, and sesame seeds.
3. Split or brittle nails
Cause: Too little biotin, a B vitamin, in the body, or lack of moisture
Solution: Approximately 1/3 of people with brittle nails benefit from taking Biotin Ultra 1mg, a nutritional supplement, two or three times a day. However, it does take a minimum of 6 months to really start working. Biotin should NOT be taken by women who are pregnant or breastfeeding, unless instructed to do so by their physician. Gelatin, colloid minerals, and calcium supplements may also help with this condition, though they aren’t as reliable as Biotin.
4. Yellow nails
Cause: Too little vitamin E or not allowing the nails enough time to breathe free of nail polish.
Solutions: 400 IU of vitamin E twice a day will usually clear up this condition. You can also add plenty of wheat germ oil, hazelnuts, peanuts, sweet potatoes, and almonds to your diet, as they are all good sources of vitamin E.
5. Horizontal dents or ridges
Causes: Dents are usually a sign that a medical condition, such as psoriasis, nutritional deficiencies, a high fever, or trauma from undergoing surgery, has impacted your nail’s ability to grow. (Nutritional deficits may also cause your fingernails to become brittle, discolored, or misshapen). Ridges are often the result of a trauma, such as frequently hitting the front edge of your nail on something hard or picking at your cuticles.
