Hair and Fibre Evidence

I worked with Xinyi for this pratical:D

Eyebrow hair 

The root is hairy looking, the tip is white and gradually turns brown in colour towards the end.

We could see the tiny hair follicles in the strand of hair.  The surface was very rough.  We also had fun playing with this hair app that could see the individual strands of other peoples' hair:D
