This image shows two strands of human hair in water. On the upper part of the strand that is more vertical, one can see small bumps on the bottom of the strand. The more horizontal strand has small air bubbles on the bottom of it, suggesting that there may be small protrusions coming from it.
The hair sample was obtained from the head of Colin Chun using scissors at 1:28 pm on 5/28/19 in Page house at the California Institute of Technology.
