There are various conditions that can cause horizontal lines on nails, which may be caused by malnutrition, fungal diseases, psoriasis and so on.
1. Malnutrition: obvious horizontal lines on nails may be caused by the lack of iron and other trace elements. Usually 10 nails start to have horizontal lines at the same time. Symptoms show that the nails are anti-nail, the gloss of nails decreases, and the surface of nails has a lot of obvious horizontal lines.
2. Nail fungal disease: Nail horizontal lines are very obvious may be the patient’s nails infected with fungi, resulting in nail deformation and thickening, and grow very obvious horizontal lines.
3. Psoriasis: obvious horizontal nail lines may also be caused by skin diseases. Some skin diseases such as psoriasis can also lead to the appearance of obvious horizontal lines on the fingernails, and the shine of the nails is reduced.
