The half-moon shape at the bottom of a nail is called a lunula. It is a part of the nail matrix, which is the tissue beneath the nail. The lunula produces the cells that will become your nails once hardened. A healthy lunula is whitish or pale in colour and is usually most visible on the thumb. The presence of a half moon is a symbol of healthy nails and body. However, an absent lunula can occur with certain health conditions.

What You'll Learn
The half-moon shape on nails is called a lunula
Not everyone has a visible lunula. It may be hidden under the skin. An absent lunula can be a sign of certain health conditions, but it does not always mean that something is wrong with your health. Sometimes, the appearance of the lunula or overall nail can be a sign of an underlying condition. For example, tetracycline medications (antibiotics used to treat acne and skin infections) can cause abnormal lunulae.

The lunula is a part of the nail matrix
The half-moon shape that appears on the nails is called the lunula. The lunula is a part of the nail matrix, which is the tissue beneath the nails. The matrix contains nerves, blood vessels and lymph. The lunula produces the cells that will become your nails once hardened. The presence of a half moon is the symbol of healthy nails and body.
The lunula is usually whitish or paler than the rest of your nails. It is most visible on the thumb, but may also appear on the index or middle finger. It is rarely visible on the little finger. When the half moon is not present at the base of the nail, it can indicate health issues. However, not being able to see your fingernail moons doesn't always mean that something is wrong with your health. It may be hidden under your skin.
The lunula is also referred to as the nail root. It is the place where each nail begins to grow. The new cells are made in the matrix and will make up the nail.

A healthy lunula is whitish or pale in colour
The half-moon shape at the bottom of your nails is called the lunula. It is a part of the nail matrix, which is the tissue beneath the nails. The lunula produces the cells that will become your nails once hardened. A healthy lunula is whitish or pale in colour and takes up a small portion of the bottom of your nail. It is usually most visible on your thumb, but you may notice that it appears smaller on your index or middle finger, gradually shrinking in size until you reach your pinkie, where it may be barely visible.
The presence of a half moon is a symbol of healthy nails and body. However, an absent lunula can also occur with certain health conditions and cause other symptoms. When the half moon is not present at the base of the nail, it may indicate health issues.
The lunula is usually whitish or pale in colour, but it can also appear slightly yellow, which is normal. The colour of the lunula can vary depending on the person's skin tone and nail condition. For example, people with darker skin tones may have a darker lunula, while those with lighter skin tones may have a lighter lunula.
The lunula is an important part of the nail matrix, and it helps to produce the cells that will become the nails. It is also a good indicator of nail and body health. If you notice any changes in the size, shape, or colour of your lunula, it is important to consult a doctor or healthcare professional. They can help determine if the changes are normal or if they indicate an underlying health condition.
