What is the Difference Between Human and Animal Hair?
🆚 Go to Comparative Table 🆚The main differences between human and animal hair lie in their morphological characteristics, color, pigment distribution, and medullary index. Some of these differences include:
- Color and Pigmentation: Human hair is generally consistent in color and pigmentation throughout the length of the hair shaft, while animal hair may exhibit radical color changes over a short distance, a phenomenon known as banding.
- Pigment Concentration: Human hair has an even distribution of pigment throughout the cortex, while animal hair has more concentrated pigmentation toward the center or medulla area.
- Medullary Index: The medullary index, which is the ratio of the medulla's width to the diameter of the hair, is smaller in human hair than in animal hair.
- Cuticle Patterns: Human hair has an imbricate scale pattern (flattened), while animal hair can have a range of patterns, including coronal (crown-like) and spinous.
- Cross-section: The cross-section of human hair is generally circular, while the cross-section of animal hair can be oval or other shapes.
- Surface Structure: The surface structure of human hair is smooth, while animal hair can have rough and spiculated surfaces.
These differences can be observed under a microscope and can be used to differentiate human hair from animal hair in various contexts, such as forensic analysis.

Comparative Table: Human vs Animal Hair
Here is a table comparing the differences between human and animal hair:
Feature | Human Hair | Animal Hair |
---|---|---|
Cross Section | Circular | Oval |
Cuticle | Present | Absent |
Surface Texture | Smooth | Rough, spiculated |
Color | Continuous | Banded. In some cases, spots or patches |
Growth | Continuous, longer | Stops growing when it reaches a certain length, shorter |
Medulla | Thinner | Thicker |
Medulla Index | Smaller | Larger |
Cuticle Pattern | Imbricate | Can vary, including spinous and coronale |
