Chris Rock did a fantastic documentary over a decade ago called "Good Hair" about the chemical and mechanical damage that Black women do to their hair to make it "more white", among other things. He was inspired to make it after his daughter asked why she didn't have "good hair". It is almost universally praised, and won a special award at Sundance in 2009.
Perhaps he'd have more awareness and sensitivity to Jada's alopecia as a result. Then again, Chris Rock has been known much of his life for not being able to discern sarcasm from seriousness, and it's defined him as a person, to the point he was told a few years ago he might be autistic. Despite the stigma of mental health, he sought diagnosis, and discovered that while he isn't autistic, he has NVLD:

I haven't seen any of this talked about in the brouhaha over last night's "moment". But it was the first thing that came to mind when it crossed my various screens.
