This is a good modern improvement. Kinda jarring to see her without her signature Max 'do!
I'm totally torn about Max's hair the same way I am about MC's 'saggy' boobs -- I actually sort of appreciate that they're just like, "This is what actual women sometimes look like! Get used to it!" Tons of people were born with thin, stringy hair, and Max is obviously one of them, and I've always loved how she just went about her businesses instead of treating it like some sort of first world crisis and signing up for pricey girl group hair so she would be a Perfect Pretty Princess and make everyone think she was born that way.
On the other hand, most days it looks like a bird flew into it and left just before photographers arrived.
