Incorporating a good hand and nail care routine with moisturizing creams or oils can help maintain nail health. Products containing ingredients like lanolin or jojoba oil are particularly effective at sealing in moisture and preventing splits.

5. Nutrient Gaps: Iron, Biotin, And Other Deficiencies Linked To Splitting

Nutritional deficiencies can manifest in various ways, including through the condition of our nails. Iron deficiency, for instance, is a common cause of brittle and splitting nails. Similarly, a lack of biotin, a B-vitamin, can result in weak nails that are more susceptible to damage.
Ensuring a balanced diet rich in vitamins and minerals can help maintain healthy nails. Foods high in iron, such as red meat, spinach, and legumes, as well as those rich in biotin, like eggs and nuts, should be included in your diet. Supplements can also be considered, though it’s best to consult with a healthcare provider before starting any new regimen.
