Human fingernails usually have a small white half-moon shape at the bottom, where they meet the finger and cuticle. Some people are born without being able to see the half-moon shape on their nails. Not having this feature could suggest a lack of vitamins or a serious health problem.
The matrix is a layer under the skin where nails grow. Create more cells using the matrix. After that, the cells group together and move out of the skin. A white half-moon shape at the bottom of a fingernail, called a lunula, could signal different health issues. The white part of the nail looks like that because there is a layer called the fifth basal elastin layer under the blood cells.
The white half-moon shape on nails usually takes up a quarter of the nail and is most visible on the thumb. Experts also say that a whiter half-moon shape on your nails means you are healthy. Different things like what you eat, how active you are, and the environment around you can affect how the Lunula grows. The white half-moon shape on your nails may get smaller, be less visible, or disappear completely if you have any of the mentioned problems.
Also, this part of the nail is very sensitive, so any pain in this area could signal a more severe health issue. Let’s find out what it could mean if the white half-moon shape on your nails is smaller or not there at all.
