Cats can have patterned fur, but can you get a tabby human? Plus we ask can we make a miniature Mars at home?
Gorillas, Orangutans, and Chimpanzees all tend to have monochromatic hair, although other primates may have more colorful coats. But, humans likely evolved from monochromatic primates.
We also had this comment from Jenny Wing on Facebook:
A few look like a tabby cat ...
Melding two zygotes can sometimes lead to chimerism - two sets of DNA in the same baby. If the different cells have different pigmentation genes, this pattern can be visible on the skin: http://www.ncbi.nlm.nih.gov/pubmed/18347288
I'm not convinced that the answer given here is the whole answer.
It is quite possible for a human to have multi-colored hair. I had a friend in school many years ago who was blond except for a spot of hair about 3 cm in diameter which was naturally black. He happened to have a birth mark on his head, and the pigmentation was incorporated into the hair. To me this suggests people with other conditions that cause large differences in skin coloration on the head might similarly have natural multi-colored head hair, but I myself only know of that one example. Of course, many people at some time in their lives naturally have multi-colored hair as their hair turns gray is certain regions before others. ps790, Thu, 7th Feb 2013
I have striped eyebrow hairs. As in, each individual hair alternates (every quarter- to half-inch) between pale blonde and med brown, just like the fur of a striped cat. The rest of my hair is all reasonably uniform. If there is really no gene for this in humans, I must have an extra or a mutation. Catwoman, apparently., Fri, 17th Jan 2014
Ok so im reading this articall and i call bull cause all my life ive been labeled as a calico because of my multi-colored patches of hair and growing up no one ever believed that my hair was natural and lead me to color my hair growing up because I always would be madefun of . So I would very much like to get in touch with someone that can explain this anomaly. Shanna Carrico, Thu, 8th Oct 2015

My daughter has natural tortoise shell hair. Several individual strands are multi-colored naturally. One strand has light blonde, red, orange, and dark blonde. She thinks she has tiger-striped hair and loves it. I can't find any instance of this inline anywhere... Casey , Tue, 5th Apr 2016
Myself and many of my family members have the same seemingly dominant trait of multicolored and multi textured hair. I have a mix, all over my head. Some hairs are black and thick, some are medium thick and brown, some are red, and some are very fine white blond. I have never know of anyone else besides my family having this trait. I constantly see researchers saying it is impossible. (Lol) Heidi C., Tue, 28th Jun 2016
Growong up we had a boy in the neighborhood who hadpatchy hair. It was brown, but he had also light patches and an almost white patch at the back of his head. Since he had short hair it was very visible. It wasn't dyed. Why would you, it wad too strange to be deliberate and it was always the same. But it looked good! I'd be interested to know how it occurred. Vanessa, Sun, 3rd Jul 2016
