Fashion has a very important role in the series, but the wigs are a spectacle of their own. As the young queen evolves into an empowered monarch, they get bigger and more intricate. Hair and makeup artist Nic Collins created a parade of beautiful head pieces that honored the ethnicity of the characters. The wigs mixed braiding and different types of hair textures, from the tightest, curliest coil to the straightest, smoothest of hair, bringing together all the textures possible, but with a modern approach. The artificial hair, mounted on a wire cage structure, was infused with flowers, laces and heavy jewelry. So much so that sometimes the actresses had to use a special brace on the back of their necks to hold them up. The wigs aren't solely an aesthetic choice, but "part of the storytelling", actress Golda Rosheuvel, who plays the older queen, told Netflix.
