Analysis of Hair/Fiber Lab

The shaft of a hair is made up of three parts. the cuticle, which is the outside, the cortex, which is the next layer in the hair, and then the medulla, which is the very center of the hair.
We discovered that every type of hair is different. Asian male hair has a spiny cuticle, a black medulla and a dark brown cortex. Black male hair is more curvy and has a brown cortex. White male has a yellowish cortex, a black and smooth cuticle, and a light colored medulla. Dog hair has a crizzled cuticle and lines in the medulla. Then the cat has a crizzled cuticle, a rough and edgy cortex and it was hard to actually see the medulla.

We also had an unknown hair sample that we had to identify using the information we gathered on different types of hair. My guess was the black male hair. The reason is because it had a darkish brown cortex, visible medulla, and a smooth cuticle. So this cancels out the Asian and cat hair, which are both brown.
