Kid with "Uncombable Hair Syndrome" has Instagram account

Uncombable hair syndrome is a real thing. It also goes by the names Pili trianguli et canaliculi, Spun-glass hair, and Cheveux incoiffables. According to Wikipedia:

The hair is normal in quantity and is usually silvery-blond or straw-colored. It is disorderly, it stands out from the scalp, and cannot be combed flat. The underlying structural anomaly is longitudinal grooving of the hair shaft, which appears triangular in cross section. This is caused by mutations in one of three possible genes; PADI3, TGM or TCHH3.

Today profiled Shilah Yin (Instagram), "one of only about 100 people in the world known to have the genetic condition."

"Shilah loves her unique hair, but that has come from constant positive reinforcement at home from friends and family," her mom Celeste Calvert-Yin, who lives in Melbourne Australia, told TODAY via email.

People often say she has hair like Doc Brown from back to the future, lucky it's one of our fave movies #uncombablehairsyndrome
