… does Jesus have blond or white hair? That doesn’t make a whole lot of sense if he was Jewish. Although there are no descriptions of what Jesus looked like in the New Testament, I think this would have stood out so much it would have been mentioned.
Maybe. I don’t know. We can only speculate. What are the odds? This is from the 1906 Jewish Encyclopedia under the subject of Hair (there may be something more current):
The true explanation of the existence of Jewish blonds has been the subject of lively discussions among anthropologists. Some believe that it is due to climate and environment (Pruner, Bey, Pritchard, Jacobs), while others attribute it to racial intermixture, particularly to the admission of Aryan blood into modern Jewry (Broca, Virchow, Schimmer, Ripley, and others). Elkind shows that the color of the hair is independent of the cranial index. Virchow’s investigations show that in the eastern or darkest provinces of Germany the proportion of blond types among Jews does not decrease; whereas in the Prussian provinces, which are predominantly blond, the Jews show the highestproportion of brunettes, and in Silesia, where the non-Jewish population is of very dark complexion, the Jews have a high percentage of blonds. The same has been shown by Schimmer to be the case in Austria. Andree ("Zur Volkskunde der Juden," pp. 34-40) points out that the fact that red and blond Jews are found in North Africa, Syria, Arabia, Persia, etc., is proof that intermarriage has had little to do with the production of the blond type in eastern Europe. He is of the opinion that there were blonds among the ancient Hebrews, and that the modern red and blond Jews are their descendants. Luschan agrees in this view. Jacobs attributes the erythrism of the Jews to defective nutrition, and shows that it is present not only among the European Jews, but also among those in Algiers, Tunis, Bosnia, Constantinople, Smyrna, and Bokhara, where the presence of Aryan blood could not be admitted.
Another thought: Ray Rogers and Anna Arnoldi in, Scientific Method Applied to the Shroud of Turin: A Review, wrote:
However, it has long been recognized that the images of the hair, moustache, and beard are anomalous. Figure 26 (sic, should be 27, shown here) shows a slightly contrast-enhanced view of the area of the face and hair. The density of the image is greatest in those areas. That can easily be explained by the inhibition of vapor diffusion through a mat of hair. Ammonia is first evolved from the lungs; therefore, amine concentrations would have been highest in the vicinity of the nose and mouth (moustache and beard).
Of course, this is assuming a diffusion model or something similar – a natural phenomenon.
