Having a bad hair day?

Everyone has had a bad hair bad at least once in their lifetime, and if they haven’t their lucky. Most people would say it’s because they need to take better care of it, or learn how to do it. But recently, scientists have found that your bad hair day, may be due to a rare genetic mutation,

They refer to this condition as, “uncombable hair syndrome”. There are three genes that are involved in this mutation: PADI3, TGM3, and TCHH. They described the hairs with this condition as dry, frizzy and pale, and absolutely impossible to comb flat. One could be diagnosed with this condition after the hairs are split in half and placed under an election microscope; if the hair has the uncombable mutation it will appear triangular or heart-shaped at the cross-section and grooved from the root to end. Luckily this mutation and condition has no impact on their life, except for a few bad hair days.
