Nails with vertical lines and cracks may be caused by malnutrition, nail plate trauma, and onychomycosis.
1. Malnutrition: Nail growth is related to nutrients such as vitamin A, vitamin B, vitamin D, and calcium. If you suffer from long-term malnutrition and lack of these types of elements, it may lead to poor nail growth, vertical lines and cracking.
2. Nail plate trauma: If the nails are soaked in water or organic solvents for a long time, or if they are often manicured, this can lead to chronic damage to the nail plate, and even vertical lines and cracking.
3. Nail fungus: commonly known as “gray nails”, mainly formed by fungal invasion of the nail plate, in addition to the symptoms of vertical lines and cracking, but also turbidity, discoloration, shrinkage, unevenness and shedding and other symptoms.
If you find unexplained vertical lines and cracks in your nails, it is recommended that you go to the hospital in time to find out the specific cause of the disease and then under the guidance of the doctor for treatment.
