Most people don’t know the meaning of the half moon at the base of the nails

Why Some People Have Visible Lunulas and Others Don’t

One of the most common questions is:
“Why can I see it on some nails but not others?”

This is completely normal.

Factors That Affect Lunula Visibility

• Nail thickness
• Finger length
• Genetics
• Nail growth rate
• Skin tone
• Circulation
• Occupation and hand use

Most people see the lunula clearly on:

• Thumbs
• Sometimes index fingers

It may be faint or absent on other fingers—and that alone is not a problem.

What the Lunula Does NOT Mean (Common Myths)

There are many myths surrounding the lunula. Let’s clear them up.

❌ It does NOT directly measure intelligence
❌ It does NOT instantly diagnose organ failure
❌ It does NOT mean you are sick if it’s small
❌ It does NOT mean you are unhealthy if it’s missing

The lunula is not a crystal ball. It’s a subtle anatomical feature that must be understood in context.
