Here’s more info about what causes lines on nails and when it might be a good idea to go see a doctor.

The essential nutrients for keeping nails healthy are:Protein: Nails are mainly made up of a protein called keratin.

Injuries like getting crushed or constantly picking at your nails can cause lines on them. These injuries can harm the skin under the nail and affect how the nail grows. - Skin Conditions
Some skin problems, like psoriasis or eczema, can cause changes in the nails, like ridges, especially around the cuticles or the skin near the nail. - Heart and Blood Vessel Illnesses.

If you see any other changes in your nails, such as color differences, or thickness changes, or if there are other symptoms along with the ridges, it’s a good idea to see a doctor. Eating well, drinking enough water, and being careful not to hurt your nails can help keep them healthy and looking good. Remember, your nails can show how healthy you are, so it’s important to take care of them.
