1 Liver disease can damage nails. 2  Thyroid diseases such as hyperthyroidism or hypothyroidism may cause brittle nails or splitting of the nail bed from the nail plate (onycholysis). 3  Severe illness or surgery may cause horizontal depressions in the nails (Beau's lines).
The condition in which your nails split is known as onychoschizia, and this common problem can arise due to a variety of factors. One cause is malnutrition or a deficiency in vitamins or minerals, like iron. Your toenails can also split or become brittle due to trauma or repeated wetting and drying.
