Medically speaking, a fingernail consists of dead, cross-linked tissue - the keratin - which is made up of up to 150 layered horn plates. If the nail plates in some places are not sufficiently fused with each other, there are widespread white spots on the nails. These are often caused by external injuries, such as shocks, and are contrary to popular opinion only in rare cases signs of deficiency symptoms. "Although iron deficiency can lead to an increased brittleness of the nails, but is usually still by additional signs - constant tiredness, headache or weakness - noticeable, " explains Schwormstedt. "Those who eat a balanced diet are usually not lacking in the necessary vitamins and minerals. Whose nails, however, change, discolor or deform despite good nutrition and proper care, should definitely consult a dermatologist ".
