Are vertical ridges dangerous?

Usually not. They are often a normal part of aging.

Can ridges disappear?

If they are caused by dryness or minor injury, they may improve as the nail grows. Age-related ridges often remain but are harmless.

Can supplements fix ridged nails?

Only if the ridges are caused by a confirmed nutritional deficiency. Taking supplements without medical advice is unlikely to help and may even be harmful in excess.

Important Note

The image suggests that striped nails always mean your body has a serious problem. This is misleading. Most vertical nail ridges are benign and related to normal aging or dryness. However, any sudden, severe, or unusual nail changes—especially dark streaks, significant thickening, or changes affecting only one nail—should be evaluated by a healthcare professional to rule out underlying conditions.
