Do you remember the microscope pictures of (my) African hair? Well, one of you asked for a comparison picture of Caucasian hair. My husband was happy to oblige. He has very dark brown straight hair. The shaft is fairly round and as my husband keeps his hair short the ends are pretty much scissor cut perfection.
Mostly round hair shaft
We both agreed that his hair is not particularly interesting (no kinks, no curls, no knots, no super ellipticity), pretty typical for someone with naturally straight hair. However, since you asked, here it is!
