Vertical ridges on fingernails are common with aging and are usually harmless. They can also be linked to dry nails, nutrient deficiencies, or certain health conditions.
See a doctor if you notice:
- Dark streaks or color changes
- Nail splitting or thickening
- Pain or swelling
Keep nails healthy by:
- Moisturizing regularly
- Staying hydrated
- Eating nutrient-rich foods
- Avoiding harsh nail treatments
