I’d trust a hairdresser when it comes to hair questions… EDIT: Turns out in real life, they did trust the hairdresser, the fact about sewing is true but the overall story is dramatized.

Bad at styling my long hair but I have definitely tried and from what I did in the few hair tutorials I followed, and from knitting, I absolutely believe that making these complicated, pretty, structured knots/loops was done by sewing.
