Those faint vertical lines appearing on your nails might seem like just another cosmetic change, but they’re actually telling an interesting story about your body’s inner workings. After age 40, many people develop these ridges due to slowing cell regeneration in the nail bed.
Beyond normal aging, these lines can become more pronounced from dehydration, nutritional deficiencies (especially biotin, iron or zinc), or frequent exposure to water and harsh chemicals. In rare cases, dramatic changes in nail texture or color could signal more serious conditions like thyroid disorders or circulation problems – making it worth mentioning to your doctor during checkups.
