In brief: Many reasons
Vertical ridges on nails are basically harmless & can be related to heredity, aging, & nail dryness or injury.
The appearance of ridges may be reduced by regular moisturizing of the nail & cuticle & avoidance of harsh soaps that are drying. Nail appearance can reflect overall health and nutrient status so supplementation may help. Consider fish oil, biotin, &/or a multivitamin with minerals.

Agreed for the most part though occasionally these can be signs of underlying conditions ie endocarditis, pulmonary issues etc...

In brief: Longitudinal Ridges
Longitudinal ridges (running from the cuticle to the free edge of the nail) may be due to aging and not a sign of any disease.

In brief: Dryness
Vertical ridges in fingernails are usually from dryness.
Try to avoid waterworking as much as possible or wear rubber gloves. Frequent hand washing can dry out nails. Biotin may help.
