Nails cracking and splitting refer to the condition where the nails become brittle, break easily, and develop splits along the edges. This can occur due to various reasons, including nutritional deficiencies, frequent exposure to water and harsh chemicals, trauma to the nail bed, underlying health conditions such as thyroid disorders or psoriasis, and aging.

Whether or not your nails are prone to cracking and splitting depends on several factors including genetics, lifestyle, and overall nail health. Some people may naturally have stronger nails, while others may be more susceptible to these issues.

Common reasons for nails to crack and split include inadequate nutrition, particularly deficiencies in vitamins like biotin, vitamin C, and iron. Environmental factors like frequent exposure to water or harsh chemicals can also weaken the nails. Trauma to the nail bed, such as excessive manicuring or using nails as tools, can lead to nail damage and splitting. Additionally, underlying health conditions like thyroid disorders or psoriasis can affect nail health, making them more prone to cracking and splitting. Aging can also contribute to nail brittleness and weakness.

Maintaining proper nail care, including keeping nails well-trimmed, moisturizing cuticles, and protecting nails from harsh chemicals, can help prevent cracking and splitting. Eating a balanced diet rich in vitamins and minerals, particularly those essential for nail health, can also promote strong nails. If nails continue to crack and split despite these measures, it may be worth consulting a healthcare professional to rule out any underlying health issues.
