Hair Texture Genetics

Is Hair Texture Determined By Genetics?

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.

The genetics of hair texture are interesting to study. Some of the most common questions people who care about their hair ask include:

Is hair type genetic?

Is hair texture genetics?

There have been plenty of studies over the years regarding hair texture genetics. The hair texture gene you have can explain why you can’t get the straight and full locks you’ve always desired or why your hair simply won’t stay curly no matter how hard you try.

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

DNA analysis might be the best way to find out about your hair texture genetics. A DNA testing kit is simple to use and your genetic DNA testing results can reveal a lot of answers to the questions you’ve had about your hair for so many years.
