27 views

The absence of half moons on your nails, or lunulae, can vary due to several factors, including genetics, nail length, and health conditions. For most people, larger lunulae are visible on their thumbs, with the visibility decreasing on the remaining fingers. In some cases, lunulae are not visible due to the skin at the base of the nail hiding them. While often a normal variation, a significant change in lunulae appearance can sometimes reflect underlying health issues, so consult a healthcare professional if you notice drastic changes.
