Vitamin B12: Nail changes in texture and color might be signs of insufficient B12.
When iron levels are low, it may lead to the appearance of spoon-shaped nails or vertical lines on the nails.
When fluids leave the body in excess, it's called dehydration.
Your nails, like the rest of your body, may feel the effects of dehydration. Your nails might weaken and develop lines if you don't consume enough water. To maintain healthy skin and nails, it's recommended to consume enough of water.
Damaging a fingernail.
Lines might appear on your nails as a result of injuries such as crushing them or repeatedly picking at them. The nail's growth may be impacted by these traumas, which can also injure the skin below the nail.
5. Skin Disorders
Deviations in the nail bed, such as ridges, may be caused by skin conditions such as psoriasis or eczema, particularly in the areas around the cuticles or the nail itself.
6. Diseases of the heart and blood vessels.
Reduced blood flow to the nails due to poor circulation might alter their appearance and growth rate. Nails may be an indicator of underlying health difficulties, such as peripheral arterial disease or heart troubles.
My last remarks
In most cases, vertical lines on your nails are just a natural part of becoming older. See a doctor if you notice any other changes in your nails, such changes in color or thickness, or if you have any symptoms in addition to the ridges. To maintain healthy and attractive nails, it's important to eat well, drink enough water, and avoid damaging them in any way. Remember that the condition of your nails is a reflection of your overall health.
