Do you have thick hair? If you do, we definitely feel you, as you have far more to do than women with “regular” hair, so to speak. Thick hair just generally means more time spent on washing it, taking care of it and looking after it. The truth is, whether you have a long, luscious, dead-straight mane or blonde curly locks, it’s all determined in the gene. I don’t want to get too much into it, because it’s really complicated and scientific, but it’s all in a gene that’s named EDAR.
