The chemistry, structure and growth of all hair is essentially the same, so the lessons learned from sheep's wool applied ... manoeuvring the snippets onto microscope slides took a steady nerve.

They went to painstaking lengths to put wool from New Zealand's finest sheep under the microscope to test long-held beliefs about the structure of hair. As it turns out it's not the number ...

His study looked only at individual cross sections of sheep hair fibers under a microscope. That snapshot of hair could result from curvature, but it could also have some twisting forces ...

After cleaning and separating hundreds of tiny cuttings of merino sheep wool, the researchers measured the curvature of each fiber, and then observed the wool under a microscope. They found that ...

However, human hair is too coarse to analyse its cell structure, so the team turned instead to fine curly merino sheep wool ... manoeuvring the snippets onto microscope slides took a steady ...
