It's been pretty well-documented that the costume and makeup team on Game of Thrones uses hair in symbolic ways throughout the series.
So I am honestly shocked that we hadn't noticed a glaring, seasons-long trend in Daenerys' hair until now.
As you probably know, the Dothraki adorn their braids after victories and cut them off after a defeat.
That's why Khal Drogo had such a looooooong braid.
And that turns out to be one of a few Dothraki traditions that Dany took to heart, because her braids have multiplied over the seasons as she's won more battles.
Cersei's hair transformation could be subject to similar symbolism: It was when she hit rock bottom and seemed defeated at the hands of the High Sparrow that her head was shaved.
