| #vertical lines on fingernails |
Nails are made up of various elements such as keratin, carbon, nitrogen, hydrogen, calcium, magnesium, copper, manganese, zinc, and iron. The nail body is made up of dead keratin cells, the lower part is soft and the upper part is stronger, and there are no nerves or blood vessels. Nails grow 3mm per month, so they regenerate themselves every 4 to 6 months, grow faster than toenails, and grow faster in summer than in winter.

| Structure of the Nail |
Healthy nails have a smooth surface, contain 7-12% moisture, and originally have faint vertical lines that are light pink in color. However, these vertical lines can be in the form of long grooves like wrinkles, which are called furrow nails.
The causes are very diverse and can be caused by hormonal and chronic circulatory disorders, inflammatory diseases, alcoholism, frostbite, etc. Sometimes they appear horizontally, and horizontal lines on the nails are caused by high fever, pregnancy, measles, zinc deficiency, mental fatigue, mental illness, etc.
In this way, fingernails are one of the indicators of health, and if there is a problem with any part of the body, the fingernails may also show abnormalities. However, if vertical lines appear on the fingernails without any specific disease, the most common cause is malnutrition such as protein, iron, or folic acid deficiency.

Vertical lines on the nails can appear in normal adults, and as we age, the grooves can become deeper due to a lack of moisture. This is because the regenerative ability of the human body decreases with age, and the speed of nail growth decreases with age for the same reason. Therefore, vertical lines on the nails due to aging are normal, so you can rest assured. Supplying moisture to the nails and maintaining a balanced diet will help improve vertical lines on the nails.

In addition to this, various types of vertical lines on the nails can occur. If brown or black vertical lines on the nails are present, they are generally caused by blood from trauma, bacterial, fungal, or viral infections, antibiotic treatment, endocrine disorders, exogenous pigmentation, excessive melanin production, etc., but in rare cases, they can be a sign of a malignant disease such as melanoma (skin cancer). The cause of melanoma is unknown, but in the case of Koreans, it mainly occurs in the extremities such as the hands and feet, so it is thought to be unrelated to exposure to ultraviolet rays. If nail melanoma is not taken seriously and left untreated, it can metastasize and in severe cases, lead to loss of an arm, so if brown or black vertical lines on the nails appear, visit a hospital to get an accurate diagnosis.
