Yes Uncombable hair syndrome is a real affliction, i did'nt make it up! But like you, when i saw it....i giggled, well up until i realised that is was REAL and that some people really do suffer with this....so you can stop giggling now!
So i present to you the horrors of UNCOMBABLE HAIR SYNDROME
So it is in fact a genetic syndrome. Apparently it affects (among other things) the cross-sectional shape of each hair, making it triangular or kidney-shaped instead of round. This causes hair that has the consistency of spun glass--and in fact, that's one of the common names of this syndrome, "spun glass hair". It's also called ectodermal dysplasmia, pili trianguli et canaliculi, loose anagen hair syndrome, Bork Syndrome, and a host of other things as well.
And apparently it's a soft indicator that there may be some other genetic issues that are more serious. Still, I'm just immature enough to be unable to stifle a snicker when I read the following, in a serious academic paper(pdf):
The hair is normal in quantity, and is usually silvery-blond or straw-colored. The hair stands out from the scalp, and its wild disorerly appearance totally resists any effort to control it with brush or comb.
Of course, there is some good news:
The eyebrows and eyelashes are normal.
And even better news:
In later childhood a considerable degree of spontaneous improvement may occur.
At least the young man in the picture has normal eyebrows ay! Thats gotta be better than a slap in the face with a wet kipper?
