White nail tips are a common and natural phenomenon, primarily due to the structure of the nail. Here’s why it happens:
- Keratin Composition: Nails are made of keratin, a protein that is naturally translucent. The nail tips appear white because they extend beyond the nail bed, where there is no underlying skin to provide color.
- Light Reflection: The free edge of the nail reflects light differently than the part attached to the nail bed, giving it a white appearance.
- Health and Thickness: Thicker or healthier nails often show more pronounced white tips, as keratin layers are more compact.
White nail tips are typically normal, though changes in color or texture could indicate underlying health concerns and may warrant a doctor’s consultation.
