Revealed :: Hair and Fiber Identification Techniques

Hair and fiber can be identified through different lengths, colors, and patters found under a microscope. For example, a black male's hair will be black and slightly curved while a dog hair will look bumpy and bubbly with a varying color.

All types of hair have different patterns, lengths and colors, and can be easily identified toward race. But when it comes to age, recent history, cause of death, etc, the process gets more complex. A piece of hair works somewhat like a tree. The rings inside the tree can identify the age of the tree and when it got certain diseases. Hair can also be used this way, as it too has rings that can be used to identify age and health.
