MotherNature.com states that weak nails can mean there are problems elsewhere in the body. Psoriasis, a condition of the skin that can lead to itching, can cause weak nails. Hyperthyrodism, which is an overactive thyroid gland, can also cause weakness. Anemia may also contribute to weak nails. In addition, it can signal a calcium deficiency.
The most common cause by far is frequent wetting and drying of nails which occurs through washing dishes and hands, cleaning, or swimming. It is also possible that your diet might be affecting your nails as certain vitamin and mineral deficiencies can cause weak flaky nails. B complex vitamins (especially biotin), calcium, and zinc have all been implicated. There are other medical conditions which can cause brittle nails such as anemia (low blood count), thyroid disorders, and skin disorders such as lichen planus and psoriasis. It is important to see your primary care doctor or dermatologist to determine the cause of your symptoms and discuss appropriate treatment.
