Uncombable Hair Syndrome
Though we’ve all had a bad hair day or two, those who suffer from this syndrome have to deal with their hair on a daily basis. Uncombable hair syndrome, also known as spun-glass hair, causes frizzy hair that won’t comb flat.
The condition usually manifests in early childhood, but by adolescence, it has mostly faded away. Uncombable hair is typically light in color and grows in a variety of directions from the scalp. A gene mutation, which affects the hair shaft, is thought to be the cause of the condition.
Cold Urticaria (Cold Hives)
Cold weather is unpleasant for most people, but for those who suffer from cold urticaria, it can cause severe reactions. Hives appear on skin that has been exposed to cold temperatures in people who have this condition.
Doctors frequently use an ice cube against a patient’s skin to diagnose this rare disorder. While the majority of sufferers develop itchy, swollen hives, the condition can also cause anaphylactic shock. After only a few minutes outside, this person’s arm was covered in hives.
