Fingernail moons are called lunula, which is Latin for little moon
Fingernail moons are the rounded shadows at the base of your nails. They are also called lunula, which is Latin for little moon. The place where each nail begins growing is known as the matrix. This is where the new cells are made that will make up the nail. The lunula is part of the matrix.
Not being able to see your fingernail moons doesn’t always mean that something is wrong with your health. Sometimes, you may only be able to see lunula on your thumbs, or possibly not on any fingers at all. In these cases, the lunula is most likely hidden under your skin. Skin colour and other factors may make the lunulae more or less visible. However, not being able to see a half-moon, or lunula, on the nails may be a sign of a vitamin deficiency, vitiligo, kidney failure, or another health condition.
Pyramidal lunula occurs when the moons of your fingernail form in a triangle shape. Most often, this is caused by an improper manicure or another kind of trauma to the fingernail. The moons may stay this way until the nail grows out and the tissue fully heals. Red lunula can indicate a number of different conditions which may significantly affect your health.

Fingernail moons, also known as lunulae, are the rounded shadows at the base of your nails. The word 'lunula' comes from the Latin for 'little moon'. Not being able to see a half-moon or lunula may be a sign of a vitamin deficiency, vitiligo, kidney failure, or another health condition. However, it's important to note that sometimes the lunulae are simply not visible. Nails grow from a pocket under the skin called the matrix, which helps to make new cells. The lunula is the visible portion of the matrix, but skin colour and other factors may make it more or less visible. In many cases, seeing this shape at the base of your fingernail isn't a cause for concern. However, if you notice any changes, it's important to tell your doctor.
