Weak and blooming nails are usually the result of insufficient care, frequent washing of dishes with strong detergents, but also too frequent varnishing and use of acetone. The delamination of the nail in several thin and cracked layers, which is professionally called onychoschisis, can also be a consequence of a lack of vitamins and minerals in the diet, as well as a hormonal imbalance.
However, if the problem lasts longer (several months), it may be an indicator of some disease. Furrows on the surface of the nail indicate a lack of iron and weaker absorption of vitamins. It can be an indicator of a bad general condition of the body or problems with the kidneys.
Distorted nails warn of arthritis or the development of that disease.
Horizontal furrows they are a sign of physical and psychological stress, but also a lack of minerals and vitamins.
Pale nails they are usually associated with aging, but they can also be a signal that some serious disease has developed (anemia, diabetes, liver and cardiovascular system disease, malnutrition...)
White nails with darker ends may indicate liver problems.
Yellow nails they are characteristic of a fungal infection of the nail plate, but they can be symptoms of psoriasis or thyroid gland disorders.
Blue nails they usually occur in people with breathing disorders, when the body does not get enough oxygen. In this case, lung disease can be suspected.
Cracked nails they are often related to diseases of the thyroid gland.
Dark lines sometimes they indicate melanoma, the most dangerous type of skin cancer.
White dots or lines through the nails, they warn of high fever, liver disease or, more likely, a lack of iron or zinc in the diet.
Red-brown dots warn of a lack of folic acid and vitamin C or protein.
