Have you noticed fine vertical lines on your nails? I wonder if this is normal or something to worry about? This often-considered minor detail could actually reveal a lot about what's happening inside your body. What if these little lines were a subtle reflection of your overall balance?

When Nails Become Messengers

Our nails, much more than just surfaces for polish, are linked to several essential functions: blood circulation, the nervous system, metabolism… Sometimes they can reflect imbalances we don't notice elsewhere. Dehydration, temporary fatigue, but also signs of deficiencies or prolonged stress: if you look more closely, these famous vertical ridges deserve more attention.
