The grass is always greener on the other side. All the straight-haired people spend time and money at the salon to create curls or waves, while the curly-haired similarly use chemicals and heat to discipline their wilder locks. This week, we're continuing with more hairy goodness from last week by looking at your hair texture.
It turns out that whether you have straight or curly hair is associated with the same EDAR gene, a gene that also influences eyebrow thickness. The 2018 genome-wide association study involving over 11,000 Japanese women found the genetic factors of various physical traits, including hair texture. The statistically significant locus in the EDAR gene, if mutated, has been associated with conditions like ectodermal dysplasia (which can cause abnormalities in your hair, teeth, skin, and glands, like missing teeth or not being able to sweat). Here's the link to the study, for your reference: https://www.ncbi.nlm.nih.gov/pubmed/29895819
